Understanding the Relationship Between Inflammatory Bowel Disease and Diet
Anne Jablonski, a feline nutrition advocate who claims to have cured her own cat’s IBD with a raw diet, describes cats with IBD as “the feline nutritional equivalent of the proverbial ‘canary in a coal mine’ among the first to exhibit dietary sensitivity to ingredients that are inappropriate for their species.”
Jablonski’s observations on feline IBD and diet are echoed by others, who argue that IBD is the result of species-inappropriate feeding. The gut microbiome plays a huge part in IBD, and this inner ecosystem is inextricably entangled with what your cat eats.
In idiopathic cases of IBD, vets often point to a rift in the relationship between the natural microbiota and the GI immune system—the gut starts to fight against itself, leading to the breakdown of friendly gut bacteria populations and a deformed intestinal lining.
As a result of lumenal damage, cats with IBD may develop leaky gut, a condition that permits toxins and bacteria to leach into the bloodstream. It’s an obvious recipe for a cat who constantly feels unwell.
Given what we know about the causes of IBD, our goal is to minimize inflammation, support a healthy gut microbiome, and help the GI tract to heal.

Prescription Cat Food for IBD
Prescription foods for IBD or general digestive health follow one of several blueprints. In general, prescription diets are hypoallergenic or novel protein-based.
By eliminating or hydrolyzing the components most often implicated in feline food allergies and sensitivities, these foods omit common inflammation triggers and give the digestive tract a chance to heal.
Some cats thrive on prescription foods, but it’s important to remember that every case of IBD is unique. Also recall that cats with IBD are still carnivores and, like every other cat on the planet, should receive a species-appropriate, meat-based diet.
This means that regardless of veterinarian endorsement, prescription dry foods are still dry foods and seldom offer anything near species-appropriate nutrition.
For example, here are the first 5 ingredients in two of the most popular IBD-focused prescription foods on the market:
- Hill’s Prescription Diet I/D: Chicken, Cracked Pearled Barley, Corn Gluten Meal, Brewers Rice, Pork Fat
- Royal Canin Feline Digestive Care: Brewers Rice, Wheat Gluten, Chicken Meal, Chicken Fat, Corn Gluten Meal
Obviously, neither of these dry foods offer species-appropriate nutrition for an obligate carnivore.
Minimally nourishing plant ingredients dwarf the animal inclusions on the list. To add to the oddness of it all, chicken is one of the top cat allergens.
When choosing a prescription diet for your cat with IBD, follow the same nutritional compass that should influence all cat food buying decisions.
Look for a food that’s rich in animal protein with moderate levels of fat and as few carbohydrates as possible.
Raw Cat Food for Cats with IBD
Of all the diets prescribed to cats with IBD, raw food shows the most promise.
It makes sense—we are all programmed to work best when eating a species-appropriate and highly-digestible diet.
For cats, that diet consists of raw meat, organs, and bones. A cat can meet all of their dietary requirements by eating raw, fresh prey alone.
Anything else—a plant-based diet full of fillers and excess—requires alteration and supplementation before it can come close to satisfying your cat’s needs. A raw diet is the simplest, most straightforward match for your cat’s body.
Raw feeding can have many benefits for cats with IBD, but you should be aware of the risks.
While most cats never get sick from the bacteria found in raw meat, it may be a risk for severely immunocompromised cats. If this worries you, you might opt for home cooked food as a less pathogenic middle ground.
Most commercially-available raw foods contain a considerable amount of bone. If your cat has constipation, excessive bone content could make the situation worse.
One alternative is to make your own raw food instead, controlling everything that goes into the recipe. This requires careful planning, research, and adherence to well-formulated recipes.
What to Look for in Cat Food for IBD
Choose foods that are highly-digestible.
Because highly-digestible animal protein is expensive, cat food manufacturers like to opt for corn gluten meal, pea protein, and other protein-rich plant ingredients instead. These foods advertise beautiful crude protein percentages, but crude protein doesn’t equal biologically available protein. To nourish your cat with minimal waste and digestive strain, choose a highly-digestible food with healthy doses of animal protein.
Avoid plant-based foods.
Cats are obligate carnivores and thrive on animal-based diets. From corn gluten meal to organic butternut squash, fruits and vegetables are neither necessary nor beneficial for any cat. For those with IBD, a species-appropriate diet is even more important.
Look for limited ingredient lists and novel proteins.
Cats can develop sensitivities to the proteins they eat most often. Since food allergies and intolerances play a part in IBD, it’s a good idea to avoid allergenic ingredients. A few of the most common cat food allergens are chicken, pork, beef, fish, dairy, and eggs.
Because meat or animal by-products may contain any variety of allergenic meats, avoid foods that include them. Instead, opt for named proteins. If you don’t know which proteins your cat is sensitive to, select novel proteins that are new to your cat’s diet.

If your cat’s always eaten chicken-based foods, choose turkey, lamb, venison, or rabbit instead.

First 5 Ingredients: Rabbit With Ground Bone, Olive Oil, Pumpkin Seed, Potassium Chloride, Sodium Phosphate Monobasic
The internet is full of stories from people who say that after trying “everything” on the market, raw food was the only thing that relieved their cat’s IBD symptoms. As the closest approximation of your cat’s natural ancestral diet, a raw diet is a highly-digestible choice that honors their biological needs.
These freeze-dried morsels from Stella & Chewy’s are made primarily from rabbit, which is a novel protein for most cats and unlikely to worsen inflammation.
The recipe is free from grains, potatoes, and other high-carbohydrate, minimally-nutritious plant ingredients.
It’s supplemented with probiotics, which can help to fortify the good bacteria in your cat’s gut, improving digestion and potentially minimizing inflammation.
- Rabbit is usually a novel protein
- Raw food has a good reputation among cats with IBD
- Supplemented with probiotics
- Highly digestible
- This food takes a few minutes to rehydrate, so it may not be convenient for every schedule.
First 5 Ingredients: Turkey, Turkey Broth, Turkey Liver, Calcium Carbonate, Potassium Chloride
With just one protein source and no grains or other ingredients that could aggravate your cat, this food is a good choice for cats with IBD.
Hound & Gatos company founder Will Post says that “the IBD cats are our largest customers.”
Unlike other foods that are loaded with plants, meats, and additives, their canned recipes are just meat, organs, broth, binders, and the supplements necessary for nutritional completeness.
The recipe is based on turkey, which is a highly-digestible protein that doesn’t make it onto any lists of the top cat allergens.
- Made from turkey, which is a good alternative to chicken
- Free from commonly irritating ingredients
- Limited ingredient list
- Highly digestible
- One of the most expensive foods on the market
First 5 Ingredients: Venison, Venison Broth, Venison Liver, Venison Lung, Venison Heart
For most cats, venison is a novel protein source and unlikely to spark an allergic reaction. This venison-based food is all about meat, organs, and bones, and doesn’t leave much room for things that could be hard on your cat’s digestion. Animal ingredients constitute 93% of the total recipe.
Note, however, that this food does contain chickpeas, which aren’t a nourishing inclusion for cats and might be difficult for some to digest.
In addition to necessary vitamins and minerals, the food is supplemented with dried kelp and New Zealand green-lipped mussel.
It’s free from potentially irritating artificial colors, flavors, or added sweeteners.
- A limited ingredient diet
- Made with a single novel protein

The remaining 4% of the recipe is dedicated to low-carbohydrate additives without a history of aggravating inflammation.
Because it contains a single source of protein, it’s a good choice for cats with suspected allergies or protein sensitivities. And turkey is one of the top meats for cats with IBD. It’s a match for poultry lovers who are sensitive to chicken.
- Made with turkey – ideal for poultry lovers who can’t tolerate chicken
- Limited ingredient list
- Meat constitutes 96% of the total recipe
- Not a very well-known food
Supplementation for Cats with IBD
In addition to a superb diet, cats with IBD can benefit from certain supplements.
Probiotic Supplementation for Cats with IBD
Remember that the relationship between bacteria and its host is profound, affecting almost every area of your cat’s health. Relevantly, bacteria is a crucial immunoregulatory agent and can help to control inflammation. Because IBD is fundamentally an inflammatory disease and a condition of dysbiosis, supplementation with “good” bacteria touches at the root of the problem.
B12 Supplementation for Cats with IBD
Because cats with IBD are unable to properly absorb nutrients, most are deficient in vitamin B12. This vitamin can be supplemented via subcutaneous injection.
Broths for Cats with IBD
Meat and fish stocks provide the building blocks that can heal the gut lining. Bone broth is mineral-rich and a good source of collagen, which contains two important amino acids (proline and glycine). These help to heal the lining of the gut and reduce intestinal inflammation. Broths also contain glycosaminoglycans or GAGs, which are building blocks for tissue repair. Provide an unseasoned, salt-free broth made from joints, bones, and meat.
Because inflammatory bowel disease affects so many cats and their humans, the web is full of resources for anyone struggling to treat their cat’s chronic GI inflammation.
