Safe and dangerous weight loss symptoms

The cat has stopped coming to the bowls, is not interested in food for several days, when there is no need to worry, and when it is time to sound the alarm?

The weight index will help the owner in this, which is subdivided into three positions:

  • Norm. On the ribs of the pet there is a thin layer of fat, the abdomen is tightened, the figure is lean. No cause for concern.

The cat eats poorly and loses weight: when you need the help of a veterinarian

If the pet ignores food for 3-4 days, does not want to drink water, you should urgently take the cat to a veterinary clinic, otherwise dehydration of the body will occur, which will lead to serious consequences, up to death.

If excessive thinness is accompanied by fever, diarrhea, vomiting, pain in the abdomen, a sharp change in behavior, then the cat should be taken to the veterinarian.

7 physiological reasons for losing weight

The owner should not immediately panic if the cat refuses to eat for a couple of days.

If your pet looks healthy, remains vigorous and playful, then the problem is most likely as follows:

  • Unusual food. Each animal has individual taste preferences, one loves fish, another. meat, the third from childhood is accustomed to dry food. A sharp change in diet, the introduction of unfamiliar foods into the diet can lead to refusal of food. Owners wishing to change their diet should do so gradually. A small amount of new feed should be added to the usual food, gradually increasing the proportion towards the new product. A violation of the diet often occurs in cases where the animal, accustomed to dry food, the owner tries to transfer to natural food. A pet, used to seeing crispy balls in a bowl, will be wary of cottage cheese or meat mixed with cereals. If the pet refuses to eat unfamiliar food, but the general condition does not cause concern, it remains to be persistent when changing the diet.
  • Heat. On hot days, even pets with an excellent appetite can refuse food. In such a situation, you should not look for cause for concern, as soon as the heat subsides, the cat itself will remember about food.
  • Stress. A cat is a sensitive animal, he is sad, worried, afraid, worried. Lack of appetite becomes the body’s response to a stressful situation. The owner must understand why the cat stopped eating, maybe she is sad because of the departure of one of the owners, worried about the fact that another pet has appeared in the house. In this case, it is worth consulting with a veterinarian who will prescribe sedatives for your pet.
  • Dirty bowls. Cats are very clean, a dirty bowl with an unpleasant odor and pieces of dried food becomes a good reason for your pet to stop eating. Cat dishes should be washed daily.
  • Hormones. Sexual reorganization of the body (estrus, pregnancy) leads to a sharp hormonal surge. During this period, the animal often stops eating. The owner does not need to worry, the cat will have an appetite, the weight loss process will be completed as soon as the hormonal background returns to normal.
  • Hairballs. The problem is relevant for furry pets. The beast licks wool to constipation.
  • Age. An elderly animal loses interest in food due to age-related changes in the body.

Treatment and assistance at home

You can help a cat at home if the true reason for losing weight is established.

If the reason is physiology, you can try to change the diet, depending on the taste and age of the pet, create comfortable living conditions, purchase preparations for forcing wool, sedatives (during hormonal surges).

If the cause of a significant decrease in body weight is an illness, you cannot self-medicate. Treatment is prescribed by a veterinarian.

5 pathological reasons for losing weight

The main causes of unhealthy thinness in cats are the development of various diseases.

  • Parasites. Unhealthy thinness occurs when the animal is affected by worms. Signs of infection: perverse taste, constipation, diarrhea, gagging, bloating, bad breath, bloody clots in the stool. In order for the animal to be healthy, it should be watered 3 times a year with means that relieve worms.
  • Viruses, infection. Viruses that have entered the body of an animal can cause the development of distemper, rabies, chlamydia, feline flu, calcivirosis, and coronavirus enteritis. Any viral disease, in addition to lack of appetite, is accompanied by various symptoms (high fever, discharge, upset stools, changes in behavior). In this case, you should immediately take the cat to the veterinary clinic.
  • Diseases of the gastrointestinal tract and internal organs. Diabetes mellitus, gastritis, inflammatory processes in the intestines, liver and kidney diseases can hurt not only people, but also animals. A sharp decrease in weight is one of the symptoms of the disease.
  • Poisoning. Cats are extremely curious, they can taste household chemicals or a poisonous plant. Fever, continuous vomiting, and a sharp decrease in body weight may be signs of food poisoning.
  • Foreign object in the mouth, dental diseases. A sharp fish bone stuck into the sky can cause refusal to eat. The pet willingly runs up to the bowls of food, but because of a foreign object in its mouth, it cannot swallow a bite. Inflammatory processes in the mouth, pain when chewing food can lead to unwillingness to eat.

What to do if your pet is weak?

When a cat refuses to eat for a long time, but regularly drinks water and has no accompanying symptoms of diseases, the owner should:

  • Stop giving the animal increased attention, provide the cat with a quiet place with a comfortable bedding, where he will not be disturbed by other household members. If the cat is trying to hide, do not disturb the animal.
  • Try changing your pet’s menu.

If alarming symptoms are added to the refusal of food, behavior has changed, it is necessary to undergo an examination at a veterinary clinic.

The veterinarian will examine the oral cavity, measure the body temperature, feel the abdomen, weigh the animal, and prescribe tests. Having identified the picture of the disease, he will recommend adequate treatment. You need to follow the recommendations, give your cat medications on time.

Why does the cat lose weight, but eats well? Physiological causes of weight loss

Weight loss in a cat is influenced by the conditions of the animal (zoohygienic, psychological), changes in the hormonal status of the animal depending on the season of the year, the nature of the animal (fastidiousness in food).

The joys of motherhood

Nature is calling

During the mating period, animals, especially those who go outside freely, can forget about food and lose weight. This condition does not require correction. After a period of “festivities” the form is restored.

When the body temperature in the room where the cat is kept drops, or if the animal walks freely outside in winter, the animal gains weight. Then in the spring, when it warms, the fats are absorbed. This is normal for tetrapods.

Signs of animal exhaustion

Before looking for a reason why a cat is thin, the owner must make sure that the animal’s weight is indeed below normal. You can determine the degree of fatness of a pet by focusing on the average weight for individuals of a particular breed.

The owner can obtain objective information about the pet’s condition by probing the cat’s body. If the ribs are well felt under the fingers, the presence of adipose tissue on them is not felt, then we can conclude that the cat has insufficient live weight. When feeling the base of the tail in an emaciated animal, bones are well felt.

If you notice a hint of exhaustion in your pet, the owner needs to look for other signs. If the cat is very thin, what to do in this situation? If exhaustion is a consequence of the disease, then other signs will certainly be observed. The following symptoms should alert the owner:

  • Decreased appetite, refusal to feed. With dental diseases and stomatitis, the cat approaches food, but does not eat or eats little.
  • Bad breath. Such a phenomenon is observed both in diseases of the oral cavity, and in pathologies of the gastrointestinal tract, kidneys, liver.
  • Apathetic state of the pet, lethargy, decreased motor activity, the animal spends a long time in a dream.
  • Diarrhea, constipation, vomiting, and other digestive problems. Blood, mucus, undigested feed particles are signs of a serious gastrointestinal illness.
  • Pale or icteric mucous membranes. May indicate liver, kidney problems.
  • Lachrymation, purulent discharge from the eyes are characteristic of many infectious diseases, helminthiasis.
  • High fever accompanies numerous infectious and inflammatory diseases.

Weight loss may be accompanied by vomiting or diarrhea, and the cat may not eat well and lose weight. Of the more “subtle” signs, the attention of the owner should also be attracted by the poor condition of the cat’s coat, hyperactivity or, conversely, unwillingness to move a lot, heaviness and lack of energy.

  • In order to exclude helminthic diseases, feces will be taken for examination in a veterinary laboratory for worms.
  • To exclude inflammation and anemia in a cat, a complete clinical blood test will be performed.
  • A complete biochemical blood test will be performed to determine the functioning of the liver, kidneys, protein content and blood sugar.
  • A urinalysis will allow the veterinarian to assess kidney function, find protein in the urine, and sometimes detect an infection.
  • In order to exclude cancer, the presence of foreign bodies in the gastrointestinal tract, fluids in the chest and abdominal cavity, an X-ray of the chest and abdominal cavity will be made.
  • With the help of an ultrasound of the abdominal cavity, a study of the liver, kidneys, pancreas, the functional state of the intestines will be carried out.
  • An elderly cat will have thyroid hormone levels measured.
  • Bile acid levels will be measured to assess liver function.

How to feed properly

If a cat loses body weight, it is possible that the fault lies with its owner, who incorrectly compiled his daily menu. There are rules, subject to which the weight of the cat will always be normal:

It is necessary to give preference to only one type of food, otherwise, in addition to weight loss, various diseases may develop. Is it natural food or branded industrial feed.

Disease of cats with worms

Worms or helminthiasis are most common in cats. Owners of their pets should clearly understand that helminthic diseases can occur even if your pets did not leave your apartment. They can become infected with existing parasitic worms through eggs of various helminthiases brought from the street on the soles of their shoes.

Cats during walks, in close contact with the environment, expose themselves to the danger of becoming infected with helminth eggs, which are in large numbers on a variety of objects. Particularly dangerous in this regard is the direct contact of your cat with other stray, stray animals.

Being inherently predators, cats never refuse the raw fish or meat offered to them, which in our time of market relations can be infected with worm infestation. Some types of worms cause characteristic pronounced symptoms of worm disease. With a strong infestation, the cat is very thin, even with a good appetite.

A sick cat vomits (vomiting in cats), sometimes with blood, there is an upset of the gastrointestinal tract-diarrhea (diarrhea in a cat). Kittens that become infected in utero can die from a blockage or rupture of the small intestine. Young cats have anemia and gastrointestinal upset. Other worms, for a long period of time, hiding in the muscles or liver of the cat do not show themselves in any way.

The defeat of the cat by ectoparasites. Very often, our cats suffer from diseases that are caused by various parasites that live both outside the animal’s body and inside it. Ectoparasites settle on the skin of cats. fleas, lice, ticks.

After hatching from eggs, the larvae, after going through a series of changes, turn into adults, which, when they meet with cats, settle in her wool and move on to a parasitic lifestyle. They bite him and drink the blood, as a result of severe flea damage, the cat loses weight. The presence of fleas in an animal may be indicated by the presence of small black crumbs on the cat’s body.

Oncological diseases. Like other types of domestic animals, cats have cancer. over, most of the neoplasms detected in cats are of a malignant nature, therefore this pathology needs complex treatment in a modern veterinary clinic with an experienced veterinary specialist.

A malignant tumor in a cat occurs as a result of a malfunction of the DNA molecules, which are the storage of information and are found in every cell of the cat.

The clinical picture of cancer in a cat depends on the organ affected by the cancer, the stage of the disease and the general condition of the cat. For many years, a neoplasm in a cat outwardly cannot appear in any way outwardly. Animal symptoms may be vague and unclear.

With liver cancer, veterinarians note in a cat general weakness, rapid fatigue, decreased appetite, a change in the consistency and color of fecal matter occurs, and a sharp decrease in weight occurs. The cat begins to develop jaundice (visible mucous membranes, the cornea of ​​the eyes and the skin becomes yellowish). Symptoms of the disease that are characteristic of liver disease in cats appear.

Bowel cancer. During clinical examination, a veterinarian in a sick cat finds the same clinical signs as in stomach cancer. In contrast to stomach cancer, fresh, scarlet blood appears in the feces, a fetid odor emanates from the feces, and bloating occurs. A fetid odor is felt from the oral cavity, and rumbling sounds upon auscultation of the intestines. Depending on the affected part of the intestine, diarrhea (diarrhea in a cat) or, conversely, constipation (constipation in a cat (coprostasis).

For more information about oncological diseases in cats, see our article. oncology in cats.

Infectious diseases in cats are caused by a variety of bacteria and viruses, in which in the body of the animal there is a decrease in body weight (emaciation) due to loss of appetite and disorders of the gastrointestinal tract. The most common infectious diseases of cats include. (infectious rhinotracheitis in cats, chlamydia in cats, mycoplasmosis in cats, bordetelliosis in cats, calcivirus infection in cats, feline panleukopenia, feline infectious peritonitis).

Almost all diseases accompanied by loss of appetite and even ingestion of a foreign object into the stomach can lead to weight loss.

Symptoms of the disease. If the kidney stones in the cat are small, and there is no blockage of the urinary tract, then the cat’s disease proceeds without pronounced clinical signs, but the results of laboratory tests of urine and blood indicate its occurrence. In such a latent period of the course of urolithiasis, the cat may show symptoms that indicate not only its development, but also allow the veterinarian to determine the localization of the urinary stone.

In a cat, the owners notice a decrease in appetite, drowsiness and depression appear. When a stone forms in the renal pelvis, the cat develops symptoms characteristic of pyelitis. Owners occasionally find blood in their cat’s urine (hematuria), especially after active movements of the cat. The presence of stones in the bladder in a cat is manifested by frequent urge to urinate and anxiety.

In the case when a kidney stone begins to move along the ureter and causes its blockage, then we observe the obstruction of the ureter. With partial obstruction of the ureters, the owners note that the cat has difficulty urinating. Urination becomes strained, during the toilet, the cat sometimes cries.

For treatment and prevention of this widespread disease in cats, see our article. Kidney stones in cats or urolithiasis.

Liver disease. Hepatitis is a common name for inflammatory diseases of the liver tissue. Hepatitis often occurs simultaneously with diseases of the stomach, intestines, pancreas and other organs. With hepatitis, the gallbladder and bile ducts are almost always involved. Hepatitis is accompanied by profound disturbances of protein, carbohydrate-fat and pigment metabolism, the disintegration of liver cells occurs.

Cirrhosis of the liver. in a cat it is accompanied by a change in its structure by the liver, due to the proliferation of connective tissue in the liver.

The main symptoms of liver disease in cats.

Vomiting in a cat. Diarrhea in a cat. Jaundice, in which there is an icteric staining of the mucous membranes and subcutaneous tissue in yellow. Itching. Discoloration of urine, from yellow to brown. Fecal discoloration from brown to brown to gray or brown. Abdominal dropsy, ascites. an increase in the volume of the abdomen due to the accumulation of fluid in the abdominal cavity.

Diseases of the digestive system lead to a cat’s weight loss, even if the amount of food eaten remains constant.

Seasonal changes

When the temperature in the room where the cat or cat is kept, or if the animals are free to walk outside in winter, cats and cats gain their live weight. In spring, with warming and increasing physical activity, especially during the period of “walks”, the animal’s fats are absorbed. This is normal for cats and dogs.

Cat stress

Cats are by nature very conservative. Any change in their environment and daily routine can stress them out. Renovation in the house, arrival of guests, change of diet, the appearance of a new pet (puppy, for example) in the apartment or the birth of a child can lead to nervousness, as a result of which the cat will eat less and lose weight

Lactating cats have a good appetite, but often lose weight while feeding kittens. If a cat has a lot of kittens, she is not able to eat as much food as is required to cover the cat’s milk production costs. As a result, the cat spends its body reserves on the formation of milk and outwardly looks emaciated. The cat will round up when the feeding process comes to an end.

Young active cats and cats who move a lot cannot keep their curvy body shapes. Aging. Older cats require less energy, move less and sleep a lot. Often they just eat little. Depletion in an older cat may be associated with health problems, so a losing old cat should be seen as soon as possible by a veterinarian.

Oral problems.

The most common occurrence in cats is stomatitis. inflammation of the oral mucosa. With stomatitis in a cat, the gums, palate, lips and tongue are affected.

Causes of stomatitis in cats.

Primary stomatitis in cats can result from:

  • Irritation and damage to the oral mucosa by coarse, sharp and caustic foods, foreign bodies, teething.
  • Thermal irritants (feeding very hot or cold food). Chemicals (irritating drugs, poisons, household chemicals, etc.).

Increased salivation. Increased by thirst. Gently chewing during meals. On examination of the oral cavity, the mucous membrane is strongly reddened, dryish and swollen. Swelling of the mucous membrane causes difficulty in the outflow of blood from the venous sinuses of the hard palate and leads to venous congestion.

Diseases of the teeth (tartar in cats, dental caries, periodontitis, various anomalies in the development of teeth). The cat may be hungry, but due to great pain when chewing, it may not eat (the cat comes to the plate sniffing food, tries to eat, then leaves), as a result of which it loses weight. Often, owners note in a cat with dental diseases an unpleasant odor from the oral cavity, increased salivation (the cat is drooling).

If, after normal or even overweight, the cat has lost a lot of weight, the reasons do not always lie in the disease. Possible natural factors:

  • Spring is the mating season. Instincts cause cats to actively mate in the spring. At this time, their hormonal background changes and their appetite decreases. Behavior becomes restless, activity increases.
  • Summer heat. Do you feel like eating a lot when it’s unbearably hot outside? It is also difficult for animals, because they also have fur. It is not abnormal if your pet’s appetite decreases in summer. The body of cats obeys natural cycles. weight gain and undercoat overgrowth by winter, fat loss and shedding in summer.
  • Stress. Separation from the owner, the appearance of a new person or animal in the house, repairs, moving, etc. When under stress, the cat is able to completely refuse to eat. After eliminating the stress factor, appetite usually returns to normal.
  • Change of feed. Not all food is to the liking of fuzzies. Diet changes, feed changes are the cause of weight loss.

Recently given birth cats that feed offspring lose a little weight. Breeds such as Abyssinian, Siamese, Bengal, Sphynx are generally not prone to gaining fat and always remain slender and wiry. The listed reasons are temporary and do not always require intervention.

As the factor is eliminated, the weight of the cat will normalize.

Symptomatic treatment

Treatment for malnutrition in a cat should be directed at the underlying cause of the condition.

Depending on the diagnosis, malnourished animals may be advised to:

  • Antibiotic therapy, treatment for worms, antibacterial drugs. for inflammatory or parasitic bowel diseases.
  • High-calorie quality diet.
  • Sometimes force feeding or tube feeding.
  • Parenteral (intravenous) nutrition. for cats unable to eat due to vomiting or regurgitation, illness.
  • Surgical treatment. removal of large tumors or foreign bodies from the intestines.

Treatment of renal, hepatic failure, supportive therapy.

Physiological causes usually do not require correction.

With pathological. you need to get rid of the reasons for losing weight.

All diseases require specific treatment and a special diet prescribed by a doctor.

The main treatment is prescribed by the veterinarian according to the results of the diagnostics and the tests passed, since it is specific for each disease. The chosen therapy is aimed at eliminating not only the symptoms, but also the cause that caused the malaise and, as a result, refusal to eat with subsequent weight loss.

Help at home should be provided after consulting a doctor, since the owner may not recognize the true reason for refusing to eat, therefore, the animal may become worse after self-treatment.

It is necessary to closely monitor the condition of the cat, as this will make sure the presence or absence of symptoms. You can slightly heat food (canned meat), so its smell will be stronger. It is important that it is not very hot.

Reasons why a cat does not eat well

In fact, it’s not always a good idea to panic when your cat hasn’t eaten anything for a couple of days. Especially in cases where the animal does not look exhausted, it does not have a fever, and there are no signs of indigestion or other malfunctioning of the body. The most common reasons why a cat does not eat anything:

    Abrupt translation into new or unusual food. Cats have their own taste preferences, just like humans, so even high quality food suddenly introduced into the diet can cause food rejection. The owner should always carefully study the composition of the feed, the manufacturer’s recommendations for feeding and remember that a new product is introduced gradually, only mixing in small quantities with the old and familiar to the animal.

This situation can also happen when a cat accustomed to industrial feed is transferred to natural food. It is unlikely that a cat that has eaten dry food will happily eat, for example, vegetables with meat or cottage cheese. But if it is only a matter of changing the usual diet, then you should not worry, the cat is simply not yet used to the innovations in its menu. The animal itself does not look sick, it does not have diarrhea, vomiting, profuse discharge from the eyes, nose.

Stressful situations.Cats are sensitive animals, they, like people, can be sad, worried, afraid of something. In a stressful situation, it may be quite normal to refuse food for a couple of days, depression, apathy. In this case, it would be good for the owner to first try to find out what is the cause of the animal’s suffering, eliminating it if possible. If the situation cannot be corrected (the death of someone who is dear to the animal, the appearance of a new pet in the house, etc.), then it will take time and participation in the cat’s life on the part of the owner. You may need to consult a veterinarian, as well as the purchase of sedatives for the purr.

Weather. When the temperature outside the window exceeds 30 (or even all 40) degrees, even the most voracious animal can look for a patch of shadow on the street or lie exhausted on the floor, forgetting about food. In such cases, you should not force-feed the cat and lament why she refuses to eat. On the hottest days, it is better not to overload the animal’s body, however, clean drinking water at such moments is more relevant than ever.

The owner does not monitor the cleanliness of the animal’s bowls. Cats are one of the cleanest animals, so the owner should wash all the cat’s dishes after each feed, or at least once a day. Dirty dishes, bowls with dried food debris, ants crowding around, and amber from sour food can make a cat refuse to eat. In addition, neglect of cleanliness can lead to various diseases.

Hormonal surge. When the body of an animal is rebuilt during puberty, during estrus and pregnancy in cats, the owner may observe the refusal of food in the pet. During the period of feline spree, animals may not eat for up to a week, especially females. The owner does not need to worry, because the cat’s appetite will return to normal as soon as the animal calms down, and the problem of changing the hormonal background will be solved by itself. It may not be superfluous to purchase vitamins, depending on the doctor’s recommendations.

Helminthiasis or external parasites in a cat. The owner should remember that the presence of worms, as well as external bloodsuckers (most often fleas) can cause a lot of problems for the animal. All parasites multiply at a tremendous speed, and then with their offspring feed on the blood of the animal and poison its body with the products of their vital activity. The owner of the cat should take preventive measures so that the body of the four-legged friend is free of worms and fleas, and also keep the room clean. If the owner suspects that the cat has worms, then the following symptoms will become alarming: diarrhea, cough, vomiting. Fleas can cause such unpleasant conditions for the cat: poor sleep, thinning of hair, itching from bites.

Lots of hair has accumulated in the cat’s stomach. In cases where the animal actively licks itself, a large amount of wool accumulates in its stomach. This problem is especially acute in the case when the owner does not comb the pet’s fur. Veterinary pharmacies sell special agents that prevent the formation of hairballs, which can be purchased by the owner of the cat. For such a problem, in addition to refusal to eat, stool disorders, vomiting are also characteristic.

Infecting a cat with a viral or bacterial infection. Even a cat that lives permanently in an apartment without leaving the house has a risk of catching an infection. The owner should be alerted to the lethargy of the pet, vomiting and diarrhea (sometimes with mucus and blood streaks), fever. The animal has no appetite during infection. By passing the tests, you can achieve the identification of the pathogen and decide on the treatment.

Anorexia. Anorexia in cats is considered to be the refusal to eat due to the loss of olfactory or tactile functions of the body. The cat loses weight, is not interested in absolutely any food, becomes lethargic, sometimes saliva can flow profusely. In the most difficult cases, the veterinarian may decide to tube feed the animal. Anorexia can be caused by nasal congestion, chemotherapy or antibiotic treatment, poisoning, and much more. Self-treatment without medical intervention can lead to the death of the animal.

Internal diseases. You can endlessly enumerate all kinds of diseases in which a cat may have no appetite: diabetes, malignant tumors, liver and kidney diseases, problems of the gastrointestinal tract and genitourinary system, diseases of the locomotor system and many, many others. If the cat, in addition to fasting for 1-2 days, has various alarming symptoms, the owner should immediately rush to consult a specialist.

As a rule, in case of any terrible diseases, the very appearance of a cat or a cat “screams” about the disease and the following symptoms appear: intestinal malfunction (constipation, diarrhea), vomiting, a sharp weight loss, discharge from the eyes (sometimes purulent), nose, dehydration. sometimes pain on contact with the affected area, plaintive meowing or complete apathy towards what is happening around. All these signs always indicate a serious health condition of the cat and diseases that should be diagnosed by taking tests, taking scrapings, biopsy, and examination by a veterinarian. Painful sensations will always cause the cat to refuse food or eat very little.

Depending on the breed, the weight of the pet varies from 3 to 7 kg. Mature animals are usually fit and thin, especially if it is a male who loses weight and gains weight constantly. The lifestyle of a healthy cat is active and dynamic. After “games” the pet wants to drink a lot, the animal eats abundantly, which has a positive effect on the digestive processes.

Dangerous weight loss symptoms include:

  • Lethargy, apathy. Mood swings are evidence of anxiety. The cat is bad and she cannot find a place for herself, does not play and refuses food.
  • Blood, frequent diarrhea. If the cat has lost weight and at the same time there are foreign inclusions in the urine and diarrhea, you need to go to the clinic and do tests.
  • Bloating. Do not confuse heavy weight with a bloated stomach. The cat may get worse and worse due to internal swelling, infection, infection, due to which he does not eat.

Why is weight loss

If a cat eats a lot, but loses weight, there are a number of reasons:

  • Worms. Helminths or worms destroy the animal’s body from the inside. Even if the cat eats a lot, the pet loses weight. Worms get inside the animal from dirty shoes, unwashed hands, a dirty tray. Cleanliness and hygiene will protect your cat. To combat worms, special means are sold, taken on average for about six months.
  • The defeat of the internal organs. The answer to the question why the cat is losing weight will help the analysis in the veterinary clinic. Disturbances in the digestive system are also noticeable externally. This is an impurity in urine and stool consistency, an unusual color. During the period of illness, the pet’s appetite decreases, he eats little.
  • Stress. A new pet can be a problem. The cat’s health is under serious stress due to nervous experience. Therefore, the once fat cat may start losing weight in a couple of months. Any change for a pet is a long addiction.
  • Summer heat. If the cat loses weight in the summer with a good appetite, this is normal. In the summer season, the fluffy animal sheds its wool, and due to temperature loads it eats less than in frosty winters.
  • Age. The old cat eats less than the young one. This is due to low mobility. An older cat that is losing weight should still be checked with a veterinarian, but for animals that sleep most of the time, weight loss is common.
  • Tumors. Neoplasms on the body, and even more so in the body, are not easy to detect. With benign tumors, the cat should not lose weight.
  • Feed. The quality of food determines the weight of the animal, how quickly it loses weight, how much it eats, and affects the processes in the body. Do not drastically change the cat’s diet from dry to liquid or homemade food. Even a dog that is less picky about food will not begin to recover from this. Changing the menu for a pet is a consistent and long process, in which it loses weight anyway.

Why does a cat lose weight, but eats well?

When the pet is eating steadily, but not gaining weight, pet owners sound the alarm. Many people believe that if a cat eats, then weight gain is a natural process. This is not entirely true. Animals, like humans, are active and dynamic, which burns extra calories and contributes to the fact that the pet loses weight. When a cat is losing weight, but eating well, this is normal. With active life, weight loss is ensured by a normal metabolism. The situation is different with sedentary cats.

Do not expect an active fat gain from a kitten. For the first 9-11 months, kittens develop a skeleton, posture, the baby gets fat and thinner. Young cats and cats become soft and plump 1-2 years after birth.

How to feed your cat with natural food?

The menu consists of two types of dishes. These are meat and dairy products.

The fermented milk set consists of low-fat cottage cheese and 1% kefir. On average, cottage cheese is served “on the table” to the cat 1-2 times a week.

When not to panic?

The activity of an animal is the best evidence of the state of health. A cat that constantly plays, runs, sleeps little and constantly asks for food is not exposed to risks and periodically loses weight. The morning volume of food is burned in a matter of hours and therefore the pet will ask for more in the afternoon. But you shouldn’t overfeed your cat.

Light poisoning for cats is a common situation, especially if the pet eats the same food as the owner. Diarrhea for two to three days does not mean a serious illness. If the problem has dragged on for more than a week, it is wise to see a specialist.

Animals experience stressful situations more difficult than humans, but faster. The introduction of a kitten, puppy, baby, a scary cat plush toy or a new person in the house can completely destroy the appetite and lead to the animal losing weight. Do not panic: after a couple of days, the cat will return to its usual eating schedule.

How to feed your cat properly?

If the cat has lost a lot of weight, the owner may have made the wrong daily diet and menu for the pet. There are a number of rules thanks to which you can maintain a stable weight of the animal and protect the family pet from threats:

Natural food and industrial feed must not be mixed. The cat develops one type of digestion, aimed at “artificial” or natural food. Your cat needs more moisture to digest the biscuits. With a constant change in diet, the digestive system cannot adapt in a timely manner, which causes the stomach and intestines to suffer.

Why does a cat need weed?

An indispensable ingredient in the diet of a cat that is losing weight is green grass. It is a natural food that has a positive effect on the functioning of the digestive system. The herb contains zinc, manganese, pantothenic acid and vitamins of various groups, which are necessary to rid the body of parasites and strengthen immunity.

Feeding a cat if it is losing weight is deliberately dangerous. A fat and fluffy animal looks cute and even adorable, but for an animal it is an extra load, a decrease in activity and the risk of various diseases that proceed in a passive form and may be invisible at the initial stage.
