Best Cat Food for IBD

Is your cat struggling with vomiting or chronic diarrhea? Have you noticed lethargy or sudden changes in your cat’s appetite? Your cat may be suffering from Inflammatory bowel disease (IBD).

Depending on the type, proper medication and nutritional therapy can help cats live comfortably and happily despite having the condition. In this article, we have reviewed the best cat food for IBD in the market today.

What is Inflammatory Bowel Disease (IBD)?

Inflammatory bowel disease is a chronic condition that affects the gastrointestinal tract caused by an over-reactive immune system in response to food or bacterial components. It can affect the cat’s stomach, small intestine, and/ or colon. Irritable bowel syndrome (IBS) on the other hand, is the severe and sudden inflammation of the gastrointestinal tract.

Cats of any age can be affected by IBD, but the condition is more common in cats aged between 5-12 years of age.

The type of IBD depends on the type of inflammatory cells present in the gastrointestinal tract or the location that is affected.

What to Look For in Cat Food for IBD

The specific adjustments to be made on your cat’s food will depend on the type of IBD, as well as the region of the gastrointestinal tract affected. Your vet may prescribe commercially available food, prescription food, or even a recipe that has the right balance of nutrients that your cat needs. 

Novel Protein

Changing your cat’s diet to one that has a protein source she has never had is one of the most important parts of managing IBD linked to food sensitivities. Select a food that is single-source protein. 

A novel protein diet and limited-ingredient diets are advisable for cats with IBD. Recipes or meals with more food ingredients increase the risk of exposing the cat to food allergens.

Food with hydrolyzed protein can also help. Hydrolyzed proteins are commonly used in vet prescription cat foods. The proteins in such foods are broken down so small that they are absorbed easily by the cat’s body without triggering allergic reactions.

High In Fiber

A higher dietary intake can be beneficial to cats with IBD. Look for cat foods with psyllium, pumpkin, or other healthy fiber sources that are not cheap fillers such as corn, wheat, or soy. Don’t hesitate to ask your vet what he or she recommends as carb or fiber sources for your kitty. This will help you narrow down your search for the right food.

Low In Fat

Depending on the type of IBD, your vet may prescribe a low-fat diet for your cat. Ask your vet about the fat percentage range that would be ideal for your cat.


Access to fresh, clean drinking water must be provided to all cats. Having a water fountain can help entice your cat to drink more. 

Increase your cat’s water consumption by feeding wet cat foods or giving freshly cooked food. In addition to canned cat foods, you can also give your cat broths to lap up, or you can pour it over their meals.

Types of Inflammatory Bowel Disease

Lymphocytic Plasmacytic Enteritis

The most common type of feline inflammatory bowel disease, lymphocytic plasmacytic enteritis means that lymphocytes and plasma cells are the primary types of inflammatory cells present in the small intestine mucosa. 

While the cause is not known, this type of IBD is associated with an abnormal immune response to environmental stimuli that when continued, creates chronic inflammation resulting in the disease.


This type of IBD involves eosinophils, which is another type of inflammatory white blood cell. According to Cornell University’s Feline Health Center, they may be the predominant cell type on occasion, but they are more commonly part of a mixed population of inflammatory cells.


This type of IBD involves neutrophils. Neutrophils are a type of white blood cell that kills and digest fungi and bacteria to help heal wounds and protect the cat’s body from infection. Neutrophilic IBD is not very common in cats.


According to the Veterinary Information Network, this rare type of IBD in cats is characterized by the presence of not periodic acid-Schiff (PAS) positive macrophages and other inflammatory cells within the lamina propria. 

It usually presents as a segmental, thickened, partially obstructed segment of the bowel. The ileum and colon appear to be the most commonly affected areas.

Forms of Inflammatory Bowel Disease Based on GI Region


  • The inflammation occurs in the small intestine
  • Common symptoms: chronic vomiting, diarrhea


  • The inflammation occurs in the stomach
  • Common symptoms: chronic vomiting


  • The inflammation occurs in the colon or the large intestine
  • Common symptoms: chronic diarrhea, blood in the stool


  • Inflammation of both the large and small intestines
  • Common symptoms: chronic diarrhea, blood in the stool


  • Inflammation of the stomach and the intestinal tract
  • Common symptoms: vomiting and diarrhea, lethargy

What Causes IBD in Cats?

While a definitive cause has not been well established, there are several possible causes of IBD in felines:

  • Bacterial infection such as Clostridium perfringens, Salmonella, or E. coli
  • Parasites such as Giardia or Tritrichomonas foetus
  • Food hypersensitivity, allergy, or intolerance to a specific protein found in the diet

IBD Symptoms 

There are several signs of IBD you can look out for. Depending on the area affected, the IBD symptoms may vary. If your cat suffers from any of these, take her to the vet:

  • Vomiting
  • Diarrhea
  • Blood in the stool
  • Lethargy
  • Not wanting to be touched or handled around the abdomen
  • Changes in appetite: poor appetite or significant increase in appetite
  • Vomiting hairballs more than once or twice a month
  • Weight loss

How is IBD Diagnosed?

If you suspect that your cat has IBD, take her to the vet. They can perform a number of tests to properly diagnose your cat’s condition and determine the type and course of action to take. This also helps rule out other causes of gastrointestinal disease.

Your vet may perform diagnostic tests such as fecal examination, urinalysis, blood work, serum biochemistries, serum thyroxine level, dietary trials, Xrays, and/or ultrasound. Tests for the feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) may also be requested.

Microscopic examination of small pieces of the intestinal lining (mucosal biopsy) is the most definitive way to diagnose the specific type of IBD. Depending on the location of the IBD, tissue samples can be obtained during abdominal surgery or endoscopic examination. Such procedures require general anesthesia.

How Is IBD Treated?


Your vet will likely prescribe broad-spectrum deworming to get rid of intestinal parasites. 

Medical Therapy

Depending on the type of IBD your cat has, your vet may prescribe corticosteroids for their anti-inflammatory and immunosuppressive properties, which have relatively few side effects in cats. These are usually taken orally. However, in cases of severe vomiting, your vet may give an injectable corticosteroid. 

Antibiotics such as metronidazole or tylosin are also given to some cats with IBD. Metronidazole contains antibiotic, anti-inflammatory, and antiprotozoal properties. Side effects to this antibiotic are quite uncommon at low dosages, but loss of appetite and vomiting may occur. 

Excessive salivation is one of the common reactions of cats after receiving the drug. This is probably a response to the unpleasant taste of the medication. 

Sulfasalazine is another medication used in treating IBD. It is commonly used if large bowel inflammation (colitis) is the predominate problem.

In more severe cases or in cases when other medical treatments have not worked, more potent immunosuppressive drugs, such as chlorambucil or azathioprine may be prescribed by the vet. The vet will need to closely monitor the patient as these types of drugs can suppress the production of white blood cells, red blood cells, and, less commonly, platelets, in the bone marrow.

Dietary Management

Dietary changes are an important part of improving the health of cats living with IBD. A change in diet can provide symptomatic relief, as food allergies play a part in the cause of gastrointestinal inflammation in some cats.

Your vet may recommend a hypoallergenic diet. A food trial using hypoallergenic diets typically includes protein or carb sources that are completely new to your cat. Common protein source choices are rabbit, venison, kangaroo, alligator, duck, etc. 

With the guidance of your vet, homemade food can also be given to your cat. Ideally, a novel protein source or one your cat has not eaten before is used, and no other meats. Increased dietary fiber can be beneficial to cats with IBD. The fiber sources must be highly digestible and the cat food recipe must also be low in fat.

Improvement may take several weeks or longer to be observed after a diet change. During a food trial period, all other food sources such as table food, other cat foods, treats, and flavored medications must be eliminated from your cat’s diet.

Many cats improve after dietary changes, medication, or a combination of both. Relapses can occur if the treatment regimen prescribed by the vet is not followed completely. However, there are cases that even with proper management, IBD symptoms may still come and go.

It is critical that cats with IBD are closely monitored by the cat owners and the vet so that relapses can be properly assessed, and the treatment can be adjusted accordingly.


While it is true that there is no cure for IBD, there are many ways to manage the disease, and lots of cats are able to live with it quite comfortably. We highly recommend working closely with your vet to enable your cat to manage IBD in the best way possible. 

Every case is different in the form or type of IBD, as well as the severity of the disease. For this reason, we have carefully selected various food options that may be suitable for cats living with the disease. 

Whether your vet recommends a novel protein-based food, or a low-fat food with limited ingredients for your cat’s IBD, all of the cat food we have selected have received positive reviews from owners of cats with IBD and other allergy and digestion-related health issues. 

We hope that our review helps you find the best food for your cat and that she enjoys her meals for more years to come.
