Why Cats Throw Up After Eating

Don't Miss

One Of The Primary Causes Of Throwing Up In Cats Is An Illness That Affects The Digestive Tract

Why Do Cats Throw Up?

There are many different possible causes of gastrointestinal upset in cats, including parasites, bacterial infections, food intolerance, indigestion, gastritis , pancreatitis , or constipation.

Some cats may vomit because they have ingested a foreign object, such as string or an insect. Other cats may vomit due to a more serious underlying intestinal disease, such as cancer or an autoimmune inflammatory condition.

Cats can also vomit due to systemic diseases, or conditions that occur outside of the gastrointestinal tract. A number of systemic illnesses can include vomiting as a clinical sign, such as diabetes, hyperthyroidism, chronic kidney disease, liver disease, and others. Toxin ingestion may also trigger vomiting, as well as some neurologic conditions.

When considering the potential causes of vomiting in cats, it can be helpful to distinguish between acute and chronic vomiting. Acute vomiting is vomiting that has developed recently and suddenly.

For example, a cat with no previous history of vomiting that vomits several times in one day is experiencing acute vomiting. Chronic vomiting, in contrast, is vomiting that occurs over a prolonged period of time.

Reasons Why Your Cat Is Throwing Up After Eating


Cat owners sometimes blame a new cat food when their cat immediately throws it back up after eating. The connection seems logical, but other factors could point to a different cause rooted in behavior.


Regurgitation, or expelling swallowed food through the mouth, can occur if your cat really loves a new food or competes with other pets in your home at mealtime.Heres what happens: a cat eats so fast that she swallows food without chewing and ingests a lot of air, too. Large pieces of food and air in the stomach will likely come back up. If your cat throws up a whole kibble shortly after eating, regurgitation is likely to blame.

What to do

If you suspect your cat is eating too fast and regurgitating, take these steps to reduce the risk.

  • Feed smaller meals more often until you notice a slow down in eating speed.
  • Rather than using a deep dish, place the cat food on a wide, flat surface, like a cookie sheet. This spreads out the kibbles and forces your cat to take more time eating. It also prevents big mouthfuls of food.
  • Transitioning

    Transitioning to a new cat food too quickly can also cause your cat to throw up. Mix increasing amounts of the new food with decreasing amounts of the old food over a seven-day period to avoid discomfort.

    If your cat is showing signs of discomfort after eating or vomits intensely or constantly, see your veterinarian immediately. Its always a good idea to consult your vet before changing cat foods.

    What Can I Do If My Cat Is Being Sick

    If your cat has been sick once or twice but otherwise appears well:

    • Remove food for two hours, but continue to provide water
    • After this time, try offering a teaspoon of their usual food or bland low-fat cooked food such as chicken or white fish
    • If they keep this down, offer small amounts every few hours for thenext 24 hours
    • Then go back to your usual routine

    If this does not resolve the sickness and you are concerned about your cat vomiting repeatedly, call your vet or, out of hours, your nearest Vet Now emergency clinic or 24/7 hospital immediately.

    You should also contact your vet if:

    • Your cat cannot keep water down
    • Has blood or unusual material in her vomit
    • Has pale or cold gums
    • Is displaying signs of listlessness, diarrhoea, fever, or another illness

    When Should I Be Concerned

    If your cat vomits several times a day, if there is blood in the vomit, if your cat is lethargic, losing weight or not eating then I recommend taking your cat to the vet as soon as possible.

    Usually, a cat that vomits once or twice a month is not a concern. If your cat vomits or regurgitates more often than you feel is normal, I recommend discussing it with your veterinarian.

    What Should I Do If My Cat Is Vomiting Undigested Food

    Why Cats Throw Up After Eating

    Some cat owners may describe their cat as ‘puke-y’, but it should be noted that frequent vomiting is never normal for a cat. Vomiting more than once a week is definitely a sign of problem. If your cat is vomiting up undigested food, begin to feed with puzzle toys and/or feed them smaller amounts more frequently. If you continue to notice your cat is vomiting undigested several times and/or in conjunction with other symptoms such as lack of appetite, weight loss, lethargy, or diarrhea, you should make an appointment with your vet right away.

    Your vet will want to start with a physical exam, checking your cat’s vital signs and palpating your cat’s abdomen. After a thorough examination, your vet may also want to run some tests, including blood work and X-rays. Blood work will check your cat’s organ function, making sure that there are no signs of liver disease or kidney disease, as well as your cat’s red blood cell and platelet levels. An X-ray study will check for any fluid in the abdomen that could potentially be blood and it may also show intestinal gas patterns that could be indicative of a blockage.

    Depending on what your doctor finds, your cat may require hospitalization for fluid therapy and supportive care, or they may just need outpatient treatments and oral medications to go home on. If your vet suspects your cat has an intestinal blockage your cat may require surgery to remove whatever the blockage is.

    There Have Been Dietary Or Food Changes

    Lastly, itâs possible that a dietary or food change could be to blame for throwing up undigested food. When you change your catâs feeding schedule, this impacts them. Therefore, if your pet ate later than typical or missed a meal, they could regurgitate their undigested food.

    Also, think about if you recently switched your cat over to different cat food. If you do this too quickly, this could shock your petâs body and make their stomach sick. Itâs best if this is a gradual process that takes place over a one to two-week period.

    Of course, if you have any nutritional concerns about what your cat is consuming, you can address those with your vet. They will be able to help sort out whatâs going on and give you ways that you can ensure your pet is getting the nutrients they need.

    Your Cat Eating Too Fast

    Some cats may eat too quickly and this can cause them to regurgitate undigested food. Feeding your cat out of a food puzzle toy can help to slow them down. Food puzzles are a great source of both play and enrichment for your cat. There are more and more manufactured food puzzles available on the market that stimulate both your cat’s predatory and foraging instincts. The added benefit of food puzzles for a cat that chronically vomits their food, though, is that it slows down the chow time so that a cat can’t eat too quickly and then get sick from it. If your cat routinely eats out of puzzle feeders and is still vomiting up their food, talk to your veterinarian.

    Dear Kitty Cleaner Upper,

    Vomiting is one of the most commonly reported clinical signs noted in feline veterinary exams. While many cat owners fancy their cats as just having sensitive stomachs or simply eating too fast, chronic vomiting is not by any means healthy or normal. In fact, chronic or intermittent vomiting could be from a wide range of reasons from benign to a precursory symptom of larger problems such as Irritable Bowel Disease and even some types of cancer. As always, if your cat is having distress, or experiences these issues often it is best to seek the advice and treatment of your pets veterinarian.

    What Are The Main Causes Of A Cat Being Sick


    While cats dont have the same reputation as dogs for scavenging, some do habitually eat things they shouldnt.

    Common causes of cats being sick include swallowing foreign objects such as pieces of string, rubber bands and ribbons, dangerous human foods such as onions and chocolate, and poisonous substances such as antifreeze, plants and human medications.

    Internal parasites and serious diseases such as cancer or diabetes are also reasons for cats throwing up. If your cat is being sick regularly, there may be an underlying problem that will need to be diagnosed by your veterinarian.

    Your Cat Ate Too Quickly

    Itâs possible that the reason that your cat is regurgitating food is that they simply ate their meal too rapidly. If you find this is occurring over and over, take note of how long it takes your pet to eat. This observation could be valuable when you bring the issue up to the vet.

    Instead, try to give your cat their food by using a food puzzle. This will allow them to slow down and take their time consuming their meal instead of guzzling it down. In addition to that, your cat will find the food puzzle to be enjoyable and amusing.

    Sometimes, you can even find a food puzzle that will stimulate the catâs foraging and predatory instincts, too shop around to find the one that is right for your pet. This will also help you sort out if the speed that your pet is eating their food is the culprit. If you have transitioned your cat to a food puzzle and they have slowed their eating speed and are still getting sick, itâs time to chat with a vet.

    Acute Or Chronic Vomiting: Illness Or Poisoning

    If your cat occasionally throws up due to a hairball or eating too quickly, there is no reason to worry. However, if the frequency of vomiting changes, there may be something else going on. Two possibilities are:

    When To Worry About Your Cat’s Vomiting

    If your cat is vomiting periodically or infrequently, avoid giving your cat any food for approximately 12 hours. Provide your cat with a couple of tablespoons of water every 30 minutes or provide them with ice cubes during this brief fasting time. After 12 hours begin providing your cat with small amounts of bland food and gradually return to normal feeding if vomiting has stopped.

    If your cat is having repeated bouts of vomiting contact your vet immediately. Continuous or severe vomiting could be a sign that your cat is seriously ill and requires immediate treatment. Contact your vet if your cat displays any of the symptoms below:

    Kidney Failure In Older Cats

    A senior cat throwing up can be a symptom of kidney failure. After working 24/7 for 12-plus years, the kidneys begin to wear out. For most cats who live 15 years or more, kidney failure writes the last chapter in the cats medical history.

    The kidneys job is not to make urine it is to get rid of waste products that are in the blood. When the waste products exceed the high end of the accepted normal range, we say the cat is in kidney failure.

    To measure kidney function, we often look at two waste products in the blood: creatinine and the blood urea nitrogen. When they become elevated, the cat has lost about 75 percent of kidney function. That is the bad news. The good news is that cats are not small dogs. When dogs lose 75 percent of kidney function, we use the term kidney failure. These poor creatures are in real trouble and usually do not live more than a few months. However, cats are tougher than dogs. They can live quite well when the kidney values are mildly elevated.

    The key is to find out about kidney insufficiency early on, so measures can be taken to prolong kidney function. Kidney insufficiency is a stage of life in which normal kidney function has passed, but in which kidney failure does not exist. The cats annual physical examination should include blood tests for kidney function .

    Eating Stuff Cats Shouldnt

    My cat throw up after eating

    Kitties are playful and curious, which can sometimes cause them to ingest items that arent meant for cats to swallow. This can include grass and plants, household items like paper clips and rubber bands, pieces of string or other toys, and just about anything else that is within reach and small enough.

    In most cases, vomiting solves the problem, but in terms of potentially poisonous plants or sharp objects, its smart to follow up with your veterinarian.

    When Does A Cat Vomiting Need Veterinary Attention

    Most cat owners have experienced the unpleasant sensation of cat sick between the toes on a nighttime bathroom trip, or as a nice addition to your favourite rug. Vomiting is the active expulsion of stomach contents, which in cats can be violent, and may have many causes. It needs to be differentiated from regurgitation: where food is brought up with minimal effort from the oesophagus before ever reaching the stomach.

    You may see warnings signs such as drooling, swallowing, licking their lips more, or hiding away. Short-term vomiting consisting of one or two episodes, or lasting less than 24 hours, in an otherwise healthy cat is usually nothing to worry about.
