My Cat Throwing Up Undigested Food

Being a pet owner means that you have to deal with any problems they may face. Your cat’s instinctive response to eating is likely to be the same. If your cat experiences this, it is possible to panic or worry that they are experiencing serious illness.

You should be aware that there are many reasons your cat might vomit, but not all of them are serious. Some of the causes your cat may be throwing up its undigested food can be simple and easy to fix.

Common reasons cats throw up

Fast eating

If kitties eat more than they can handle, they may develop a stretch reflex that causes them to re-gurgitate the food. A poor diet and inconsistent eating habits are often linked to gagging.

Allergies or adverse food reactions

Cats can be allergic to certain ingredients that could cause chronic vomiting. Most common allergens in cats are eggs, poultry, meat, soy, egg, turkey, and lamb. Itchy skin and diarrhea are common symptoms in cats with food allergies. Food allergies can lead to food poisoning, food intolerance, food allergies, food reactions, food additive reactions, food allergies, food sensitivities, or cats eating food that isn’t suitable for them.

Severe Abdominal Conditions

Cats will vomit visible and loudly to get rid of food. As they expell the contents of their stomach, their entire body will likely start to heave.

Cats are more fussy than dogs, and they tend to be less likely to eat things they shouldn’t. However, they can sometimes take a liking to dangerous foods. Sometimes it’s over-zealous play that gets out of control, when cats swallow cotton thread or tinsel.


It can be very distressing for your cat to throw up undigested dry food. However, it will become even more serious if your cat has hairballs. Cats are very clean and enjoy taking care of themselves.

The tiny hooks on the cat’s tongue could accidentally carry loose hair from their bodies to the inside. It is something to be concerned about if hairballs form in your cat’s stomach. Your cat could experience nausea and vomiting due to hair that isn’t digestible.

Because they lick their hair while grooming, long-haired cats might throw up their food. Although excess hair is not a common problem in long-haired cats it is more common than in their shorter-haired feline friends.

Brush your cat frequently to reduce the likelihood of hairball formation. Special foods are available for hairball-prone cats.

Changes In Diet Or Feeding Regime

Cats can be hypersensitive to food and can become stressed if they are subjected to sudden changes in their diet. Changes to their routine or feeding schedule can cause them to resent food or regurgitate. To ensure that your cat doesn’t feel threatened or upset by any new diet or feeding regimen, nutritionists recommend that you transition slowly.

Your cat may have problems if it is not given enough time to adjust to the new diet. You should gradually reduce the amount of the old food and replace it with the new one over several weeks.

Toxic Substances

Cats can also eat toxic substances, in addition to foreign objects that may get lodged in the digestive system. Even though your cat may appear normal, poisonous substances can be very dangerous and even life-threatening. Commonly ingested toxic substances include antifreeze, coffee and onion. Cats can also be poisoned by many houseplants.

You should immediately notify your veterinarian if your cat is found to have eaten or drunk any of these substances. Other symptoms that could indicate your cat has consumed toxic substances include seizures, lethargy and increased thirst.

Gut Inflammation

IBD (inflammatory bowel disease) can cause cat diarrhea and vomiting. Lymphoma, a type of intestinal cancer, has been linked to chronic untreated IBD. Symptoms such as vomiting and diarrhea can also be caused by bacterial overgrowth.

This can lead to vomiting if the foreign material becomes lodged in the stomach. It is important to immediately contact your veterinarian if your cat is experiencing vomiting or other symptoms.

Grass Eating

Perhaps your cat is eating grass and then vomiting. You might have noticed grass in piles of vomit all around your house. Although cats enjoy grass, the shape and lengths of the grass can cause irritation to the gag reflex.


Cats love to experiment with their curiosity and put things in their mouths. This doesn’t always work out well. You’ve likely seen your cat swallow many items, even if they aren’t food. They won’t cause problems if they are small and can move to the litter box.

This should be a warning sign to your cat that they are not being able to ingest any foreign objects. If the foreign object is not easily removed by vomiting, obstruction can be a serious problem that could lead to an emergency situation. You should contact your vet immediately if the cat is having trouble breathing, throwing up or throwing up. You can put a small toy or a piece of plastic from your home, or fabric in the cat’s mouth. You’ll be able to identify the cause of the obstruction if you find a strange object in the vomit. The vomiting will also be explained.

Does it make sense for a cat to urinate every day? Is it really that bad?

It is not unusual for cats to vomit every day due to overeating. However, there may be other reasons your cat might be vomiting. If your cat vomits often, it is worth seeking the assurance of a veterinarian.

What is the Difference Between Vomiting and Regurgitation?

Sometimes vomiting isn’t always caused by vomiting. Regurgitation can sometimes be confused with vomiting. Knowing the difference can help your veterinarian diagnose the problem. Regurgitation can be mistakenly confused with vomiting. However, unlike vomited food regurgitated food is not yet digested by the stomach acids.

Knowing if your cat is vomiting or regurgitating food can help you determine the cause and treatment options. Note if your cat is heaving, abdominal effort or just grabbing food easily.

They are Regurgitating their Food

Cats who only eat dry food will often ingest the food almost immediately after they have finished eating. The dry food expands when it mixes with their stomach contents and causes discomfort.

Regurgitation can be caused by something as simple as the dry food’s shape. To test whether kitty can tolerate pellets versus star-shaped and square pieces of cat kibble, try different types of dry food.

What can I give my cat to stop him vomiting?
