What is IBD in cats?

Feline inflammatory bowel disease (IBD) affects the gastrointestinal (GI) tract. When a cat has IBD, their GI tract (part of or all the intestines) becomes chronically inflamed and irritated. 

IBD happens when inflammatory cells penetrate the GI tract’s walls. The walls begin to thicken, disrupting the GI tract’s ability to digest and absorb food properly.

This disease can affect cats of any age, but it’s most common in middle-aged and senior cats. Inflammatory Bowel Disease can also create different problems. This depends on which part of the GI tract it affects and the type of cells involved.

When the inflammatory cells affect the stomach, it’s called gastritis. When inflammation affects the large intestine, we refer to it as colitis. When there is inflammation of the mouth in cats, it’s called stomatitis, which causes terrible oral pain and poor appetite.

The most common type of IBD is lymphocytic plasmacytic enteritis. This involves inflammatory plasma cells and lymphocytes invading the small intestine.

Sometimes, IBD leads to inflammation in other abdominal organs. Most commonly, the liver and pancreas.

What are the causes of IBD in cats?

The exact cause of IBD is still unknown. Experts suggest it’s an effect of several factors.

Current evidence suggests that inflammation may be a reaction to an underlying cause related to:

  • The immune system
  • Bacterial populations
  • Diet
  • Environmental factors

There’s also a possible link between IBD and genetic deformities of the immune system. This was first discovered in dogs and people, but it’s possible in cats too.

Other causes of IBD may include:

  • A bacterial infection or imbalance, for example, E. coli or salmonella
  • Allergies or food intolerance
  • Parasitic infection with single-celled parasites or worms

Many cats can be helped through alternative care with minimal long-term pharmaceuticals.

Symptoms of IBD in cats

Cats with IBD may show different symptoms, which are often a clue to the underlying problem. IBD symptoms may also vary in frequency and severity. Here are a few common signs:

  • General physical condition may be ‘off’
  • Weight loss
  • Vomiting
  • Diarrhea
  • Constipation
  • Bloody stools
  • Decreased appetite
  • Lethargy

Is IBD in cats painful?

Cats with IBD produce excessive amounts of gas. This leads to abdominal discomfort.

Inflammatory bowel disease can also cause cramping and muscle spasms. You might notice your cat sitting hunched over, unusually quiet, or licking their belly to ‘relieve’ the pain.

The most common signs are vomiting and diarrhea. Both are a sign of nausea.

How is inflammatory bowel disease treated in cats?

The first step to treating cats with IBD is to determine the underlying cause. Most of the time, the exact cause is unknown. In such cases, the vet labels IBD as “idiopathic.” This means that the disease is there, but without an identifiable trigger.

Here are a few ways veterinarians may treat cats with IBD:

Dietary therapy

For some cats with IBD, changing their diet can help. Some cats may need a prescription diet or a veterinary diet. Consult your vet about the best approach, but there are generally three ways of accomplishing this if a prescription diet isn’t necessary.

  1. Bland diet: Switching to a bland, easily digestible diet may be an option. The diet will need to be nutritionally balanced for long-term feeding.
  2. Limited-ingredient diets (novel diets): This is also known as a novel protein diet. The thought is that a cat is unlikely to have an inflammatory reaction to ingredients they’ve never had before.
  3. Hydrolyzed diets: With your vet’s help, try switching to a commercial cat food containing a novel protein source. Your vet may recommend a novel protein like rabbit, venison, or duck. Essentially, something your cat wouldn’t usually eat. If successful, the IBD symptoms will disappear.

While on a food trial diet, avoid giving your cat treats or other foods. Food trials take time, lasting anywhere between 6 to 12 weeks.


If your cat has a parasite, a dewormer might help. Vets generally recommend broad-spectrum deworming, as it’s not always precisely known what parasite moved into the GI tract.

B12 supplementation

Supplementing with vitamin B12 is a conventional treatment for IBD in cats. Many cats with IBD can’t absorb B12, so your vet may give your cat an injection of this vital nutrient.


Treating IBD with medications is usually a last resort. Vets might recommend it when the dietary therapy you tried was unsuccessful. Or, if they couldn’t detect an underlying cause.

Medications to treat cats with IBD are mostly used to suppress the reaction. For this, vets usually prescribe steroids like prednisone first. They may try other medicines, like antibiotics, if that fails. Your cat could be on a short-term or longer-term antibiotic therapy.

After a month or so, your vet may examine your cat and perhaps discontinue the medication. If symptoms recur, you need to resume the medicine. However, with many cats, long-term treatment with steroids is required.

IBD and hairballs

Cats vomit up hairballs for a variety of reasons. It’s usually a result of your cat’s grooming routine, or they can’t pass the hair through their intestines.

If your cat has IBD, the hair must pass through the digestive tract with no problems. If you suspect your cat’s hairballs aren’t a result of excessive grooming, you’ll want to contact your vet.

Sometimes, finding the best cat food for hairballs and vomiting may help.

Keep an eye on your cat and consult your vet if the hairballs are excessive.

Worst foods for cats with IBD

Worst foods for cats with sensitive stomachs

Giving certain foods to a kitty with a sensitive stomach could be a trigger. (If your cat has a particularly sensitive stomach check out our roundup for the best sensitive stomach cat foods). Research tells us that the worst foods to feed a cat with a sensitive stomach include:

  • Fat: Offering your cat fat can lead to intestinal distress, causing vomiting and diarrhea.
  • Raw eggs: The biggest issue with raw eggs is the risk of food poisoning. Bacteria, like salmonella and E. coli, are even possible causes of IBD. Another problem with raw eggs is a protein called avidin. Although rare, this can interfere with how your cat’s body absorbs vitamin B.
  • Raw meat, poultry, and fish: Like eggs, these can contain both salmonella and E. coli bacteria. Additionally, raw fish holds an enzyme that destroys thiamine—a vital vitamin. Thiamine deficiency can lead to severe neurological problems, even a coma.

Can cats with IBD eat dry food?

Cats with IBD can easily consume dry cat food. However, you may have to add a little chicken or meat-based broth. IBD can lead to dehydration, so adding a little moisture can help your cat quickly digest their dry food

Your vet will help you identify the proper dry food diet if you’re switching to a limited-ingredient diet or a novel protein diet.

Canned cat food might be easier on their digestive system. It’s rich in moisture and doesn’t expand as much in the stomach.

That said, if your cat isn’t a big fan of canned cat food, stick to dry cat food. We’ve reviewed several reputable dry cat food options.  If in doubt, always consult your vet for guidance.

Choosing the best food for cats with IBD

Here are some key factors and criteria we used when researching the best cat food for IBD. Please note that it’s best to consult your vet for initial guidance on how best to approach your cat’s condition after a diagnosis has been made.

Limited-ingredient diets

Because food allergies are often to blame for IBD, it’s essential to eliminate some ingredients.

Plenty of brands offer limited-ingredient diets. These foods are often free of the usual proteins, such as pork, chicken, beef, and fish. Instead, they may include novel protein, like rabbit, duck, turkey, or venison.

You can find this type of food in both dry and canned options.

Nutritional Value

Reading the label for the food’s nutritional value is essential. Cats require a complete and balanced diet to thrive.

Animal protein is vital in their diet and should be one of the first on the list. In addition to this, there should be some fat and minimal carbohydrates. Lastly, look for essential vitamins and minerals, even in limited-ingredient diets.

Looking at cat food labels can be confusing! Fortunately, the AAFCO now has guidelines on what brands must include and what claims they can’t make.

  • Always read the cat food label: There is a system for listing the ingredients on your cat’s food label, and understanding it will help you pick the best ingredients.
  • The FDA mandates that ingredients must be listed from most to least based on their weight.
  • The majority of your cat’s food is made from the first few ingredients listed, so you want to be sure they aren’t fillers. Instead, look for whole foods.

Avoid inflammation-triggering ingredients

For cats with IBD, it’s crucial to avoid ingredients that may trigger inflammation in their GI tract. Some elements that can cause allergies you should look for on food labels are:

  • Lactose
  • Dairy
  • Eggs
  • Grains
  • Artificial colors and preservatives

Moisture-rich foods are generally best since they help prevent dehydration. Canned cat foods are always the best choice.

Since we’re all well aware of how picky cats can be, it isn’t always possible to switch from dry to canned.

Add moisture to the dry kibble using a poultry broth or a little warm water. You can also microwave it for 30-seconds to make the food more palatable.

Another great option is adding a cat water fountain to your home. We’ve reviewed 5 of the best cat water fountains.
