Cat throwing up food but acting normal! All you need to know!


Does your cat throwing up food but acting normal? Sometimes vomiting is normal in cats, but sometimes it is a serious problem. Vomiting is always a protective reaction of the body. The situation when the animal is sick is unpleasant for both the cat and the owner. Vomiting in a cat occurs for various reasons: from inappropriate food to malfunctioning of internal organs. An attack does not always require a veterinarian’s help – in some cases, the owner successfully copes with the problem at home.

But for every situation when the cat is sick, you need to pay attention. Objects that enter the stomach and cause vomiting may cause internal injury. Nausea can be a symptom of various animal diseases.

Of course, this is an unpleasant condition not only for the cat but also for you. During this period, you should take care of the cat, monitor its condition, and clean it up. To do this, let’s look at the most common causes of vomiting in cats so that you can prevent vomiting in some cases, if possible.

 The reasons your cat vomits.

Your cat’s food is of poor quality or not suitable for the cat.

It sometimes happens that the proteins in your cat’s food are not suitable for her. It can also be due to an unbalanced diet. Try to vary your cat’s diet. So that she gets all the proteins and other nutrients she needs.

Most commercial cat foods contain Taurine. It is an amino acid that is essential for the normal growth and development of cats. Sometimes it is missing, or the wrong amount was added. It can also cause discomfort and vomiting in your cat. Just give your cat a different diet.

You have changed your cat’s food/diet.

Change the eating habits of your cats gradually. Sometimes it can take up to 7-10 days to change the diet. If you do this faster, it can backfire and end in vomiting.

If you decide to switch your cat from wet food to dry food or from home food to commercial food, you should do it gradually. Each feed manufacturer usually has their recommendations on this matter. Sometimes, just changing the brand of food can cause the cat to vomit but behave normally.

In addition to vomiting, diarrhea is also possible in a cat. Veterinarians do not recommend feeding a cat with human food if the main food is a commercial food.

Your cat is eating too fast / overeating.

The esophagus in cats is horizontal. A large portion of swallowing food prevents the stomach from completely digesting it, and as a result, food comes back through the mouth. Eating too quickly can cause regurgitation of food in just minutes.

Cats may eat quickly due to competition with other felines and overeat. And it can provoke vomiting within minutes after eating. To avoid this, use feeders that dispense feed in portions. Will help you avoid overeating and eat more slowly.

Some cats may also vomit due to a lack of digestive enzymes or pancreatitis. It happens when the pancreas does not secrete the enzymes needed to break down food.

Poisoning/toxins. Food allergies.

Stomach cleansing, including diarrhea, is the body’s standard defense mechanism when exposed to a toxin. In such cases, cats are often nauseous after each meal, their appetite decreases, aversion to food appears, and general deterioration is observed.

Sometimes it can be due to food, such as chocolate, milk, raw dough. This food is difficult for cats to digest and can cause gastrointestinal upset, and the cat is vomiting. In any case, if you suspect poisoning with products that are toxic to your cat, immediately take it to the clinic or call your vet.

Cats, like humans, can suffer from allergies. If you notice a food allergy in your pet, change the food or not feed the product that is causing the allergy symptoms. You may find itching, redness, or bald patches in your cat as some of the allergy symptoms. Cat is vomiting; in this case, it can also occur.

It could be a serious illness or infection. Infection with parasites.

Bacterial and viral infections in felines, such as distemper and hepatitis, directly or indirectly affect the stomach. Vomiting in such cases will be one of the symptoms of the disease. Also, a cat is vomiting is a possible companion of oncology, liver, kidney, gallbladder diseases, gastritis, pancreatitis, and other disorders. But in such cases, the general health of your cat will be poor.

Parasites are also a common cause of cat is vomiting. In this case, the cat vomits yellow mucus. However, having noticed this, do not rush to immediately give the cat antiparasitic drugs – if you are not a vet, you can easily make a mistake in the diagnosis, and anthelmintic pills will only aggravate the disease. It is better to consult your doctor first.

It could be due to hairballs.

Probably one of the most common reasons cats vomit is hairballs. Each cat burps its hair periodically. The problem can also be observed in bald breeds adjacent to hairy cats. When licked, the fur accumulates in the cat’s gastrointestinal tract and needs to be released. Do not be alarmed if the cat periodically (1-2 times a week) belches dense hair sausages or balls.

Problems are indicated by more frequent vomiting, constipation, lack of appetite, depression, and bloating. Symptoms indicate an overflow of hair in the stomach and intestines. Look into a cat food that is formulated for hairballs.

Feline curiosity.

Kittens and adult cats are interested in non-food items such as broomsticks, houseplants, decorative items (such as ikebana), foil, or Christmas decorations. Some enter the body by accident while playing. Others are eaten deliberately.

Cat vomiting of undigested food is a potential sign that the chosen food or diet product is not suitable for the pet.

Reaction to drugs.

An involuntary contraction of the stomach is a side effect of certain medications. It is usually warned by prescribing veterinarians or instructions. Nausea and vomiting in cats are also observed after general anesthesia. If the animal vomits soon after surgery, then it has not yet recovered from the anesthesia.

Pregnancy of a cat.

Cat throwing up food but acting normalVomiting in cats can also occur due to pregnancy, and then you do not need to be afraid at all. Firstly, developing and increasing in size, kittens begin to squeeze internal organs, including the stomach, and it can no longer hold as much food as before.

Secondly, the reason may be the same as in humans – toxicosis. However, all this does not mean that a pregnant cat cannot be poisoned, or her gastritis will not worsen, so monitor her health and, if necessary, contact a vet.


It also happens that vomiting in cats starts with stress. Furry hunters are very emotional creatures, and if there is a shock in their life, they are anxious about it, which can be expressed, among other things, in loss of appetite, nausea, and throwing up food.

You should also pay attention to the color of the vomit.

Foam vomiting. It is one of the most common types of cat vomiting. In this case, a white foamy mass, practically odorless, is expelled from the stomach. If this throwing up food occurs once, do not worry. A white foamy secretion is produced in the stomach of cats to protect its walls from acid, and sometimes the excess is released in the form of a cat is vomiting. If this is repeated regularly, this signals the onset of gastritis, and the cat should be transferred to a sparing diet.

Vomiting of bile. Sometimes the vomit can be yellow. Indicates a strong splash of bile into the stomach, which is a sure sign of abnormalities in the liver and bile ducts. Happens when poisoning or eating too fatty foods, but the vet makes the final diagnosis. The owner, who noticed similar manifestations in his cat, should transfer the cat to a diet, excluding fatty meat and fish from food.

Yellow vomit. If the vomit is colored yellow, it is worth talking about the liver and bile ducts’ violations with a greater degree of probability. Also, yellow-colored foam comes out when throwing up food if parasites are in the animal’s digestive system. In this case, it is necessary to give the cat an anthelmintic drug.

Although, perhaps, the yellow color of the vomit has been acquired due to the color of the food eaten the day before, so remember what you fed your cat.

Vomiting blood. This symptom rightly frightens all owners because, as a rule, the presence of blood in the vomit signals a serious malfunction in the cat’s body. If the blood is dark and clotted, we talk about pathology in the stomach, while a scarlet color means problems in the esophagus or mouth.

And the most harmless reason here may be a wound in the mouth. For example, blood could appear from a damaged tooth. However, if we are talking, for example, about a fishbone stuck into the gum or throat, then the animal is unlikely to cope without assistance. But more often, the cause of bloody vomiting is acute gastritis, a stomach ulcer, or even a tumor.

Therefore, if your cat vomits blood, you do not need to make assumptions about the reasons. Still, you must immediately take him to the vet, since in any case, such a symptom indicates serious disorders in the body.

Green vomit. Like yellow, a similar color of vomit indicates a malfunction in the liver. Bile, especially stagnant, can turn green. And this symptom most often indicates problems with the gallbladder, such as stones or poor patency of the bile ducts.

What if your cat is throwing up food but acting normal?

Watching your cat vomit can be frustrating, and you should take whatever decisions you can to help it recover quickly. If your cat is throwing up food but acting normal and it otherwise looks healthy, has a good appetite for normal food and drink, has not lost weight, has normal behavior and activity levels, and vomiting is rare, then you have nothing to worry about.

The usual treatment to stop vomiting is not to give food and water until it stops, and then slowly introduce water and a soft diet.

Cat throwing up food but acting normalAs we have said, vomiting is not a disease, but a symptom, so it is necessary to keep in mind the causes of nausea and vomiting.

First, make sure that the cat always gets fresh and quality food without excess fat—secondly, timely prevention of helminthiasis.

Thirdly, periodically give a paste to remove hairballs from the stomach. And, of course, remember that cats are vulnerable creatures, easily exposed to stress, so you should take care of the psyche of your cat, not offend or injure him. In order to help them get better as soon as possible.

Popular questions and answers

Of course, noticing that our pet has vomited, the first thing we do is find out why we call or write to the vet. Consider the questions most often asked by cat owners.

Why did the animal vomit white foam when switching to a news feed?

 If this is not repeated regularly, you should not panic. Foam is formed in the stomach to protect its walls, and when switching to a new food, excess of this secretion can be produced, which is removed from the stomach through vomiting.

The kitten began to vomit from the most harmless food. What to do? 

Vomiting of undigested food or white foam in small kittens is a natural process. When a baby switches from mother’s milk to independent nutrition, his stomach is just learning to cope with rough food, and this does not always work out the first time. Over time, this vomiting goes away. It is necessary to sound the alarm if the vomit contains blood, bile, or parasites.

Why did the cat start to vomit after sterilization?

 Do not be afraid. Sometimes this is how the reaction to anesthesia is expressed. Like a person after an operation, at first, the kitty can be cloudy, which causes vomiting. It passes quickly

If the cat vomits food? 

There may be two reasons. The first and most common is that your cat overeat. Many animals, especially those whose childhood was spent on the street, have no sense of proportion and all the time they want to gorge themselves for the future. Therefore, if there is more food in a bowl than the stomach can hold, they often overeat, so that the body has to get rid of the excess food.

In this case, there is no need to worry. You need to reduce the portion and not succumb to the sweet glances with which these natural-born manipulators are good at twisting ropes out of us.

Another reason is that the food did not fit. Then you need to pick up another one, and here it is worth consulting with your vet about what kind of food your cat needs.

If a cat vomits hair? 

Is perhaps the most harmless manifestation. Vomiting of hair is observed in absolutely all cats, especially furry cats and especially during seasonal molting. The fact is that, when washing, the animal licks off a lot of fallen hairs with its rough tongue and swallows them. They accumulate in the stomach because they are very poorly digested and, in the end, a rather large hairball from there, which the cat can get rid of only with the help of vomiting.

To avoid or minimize this, it is necessary from time to time to give your pets a special paste for removing hairballs, which is sold in all cat stores and veterinary pharmacies, and introduce food with ingredients to remove wool into the diet. If cats have the opportunity to walk outside, they can eat grass for the same purpose. At home, animals often try to chew plastic bags to induce a gag reflex, and if you notice this, then urgently buy pasta.


Suppose your cat vomits all day. There are other symptoms. Your pet is weak, lazy, and does not want to drink. He has diarrhea or any other symptom not seen in healthy cats. It is necessary to go to the clinic or call a doctor home urgently in all these cases.

Usually, the vet asks for very detailed clinical information and performs a thorough physical examination. The information she receives will help her narrow down possible causes from an extensive list of possible ones.

Depending on the response, your vet may need to evaluate your cat’s vomiting further. These additional tests may include stool analysis, blood tests, and urinalysis (depending on medical history, response to trial therapy, and clinical assessment). Treatment depends on the underlying cause.
