A bland diet of boiled chicken and white rice is the go-to meal for a cat with diarrhea, and most mild cases resolve within a day or two of dietary adjustment. The key is keeping your cat fed and hydrated while giving their digestive system a break from their regular food. If diarrhea is frequent, watery, or bloody, or lasts more than two days, that signals something more serious than a dietary upset.
Start With a Simple Bland Diet
The standard bland diet for cats with diarrhea is 75% boiled white rice mixed with 25% boiled lean chicken breast (no skin, no bones). You can also use lean ground beef, with sirloin being the leanest option. Boil the meat thoroughly and avoid adding any oil, butter, salt, or seasoning. The goal is a soft, easy-to-digest meal that won’t further irritate the gut.
Feed small portions three to four times a day rather than one or two large meals. Smaller servings are gentler on an already upset digestive tract. You can premake the bland diet and store it in the refrigerator for up to 72 hours, warming each serving slightly before offering it. Some cats are notoriously reluctant to eat rice, so if yours turns up their nose, plain boiled chicken alone is a reasonable fallback. Puréed chicken or turkey baby food (with no onion or garlic in the ingredients) is another option that many cats will accept.
Stay on the bland diet for two to three days after the diarrhea stops. Then gradually transition back to your cat’s regular food by mixing increasing amounts of it into the bland diet over four to five days. Switching back too quickly can restart the problem.
Add Pumpkin for Extra Fiber
Plain canned pumpkin (not pumpkin pie filling, which contains sugar and spices) is a useful addition to a bland diet. The soluble fiber in pumpkin absorbs water in the intestines and adds bulk to loose stools, helping them firm up. Most cats do well with 1 to 4 teaspoons mixed into their food per day, depending on their size and how severe the diarrhea is. Start with a single teaspoon and increase if needed.
Not every cat likes pumpkin, and that’s fine. It’s a helpful supplement, not a requirement. If your cat won’t eat food with pumpkin stirred in, skip it rather than letting them go without eating.
Keep Hydration a Priority
Diarrhea pulls water out of the body quickly, and cats are already prone to mild dehydration under normal circumstances. Make sure fresh water is always available, and consider placing multiple bowls around the house. Some cats drink more readily from a running water fountain than a still bowl.
You can check for dehydration at home by gently pinching and lifting the skin between your cat’s shoulder blades or along the side of the chest. In a well-hydrated cat, the skin snaps back into place immediately. If it stays tented or returns slowly, your cat is likely more than 5% dehydrated and needs veterinary attention. Other dehydration signs include dry gums, sunken eyes, and lethargy. Keep in mind that older cats and cats with certain skin conditions may have reduced skin elasticity regardless of hydration, so no single test is definitive on its own.
Offering wet food or adding a splash of warm water to the bland diet can help increase fluid intake for cats who aren’t drinking enough on their own.
Probiotics Can Help Recovery
Feline-specific probiotics can support gut recovery during and after a bout of diarrhea. They work by replenishing beneficial bacteria in the intestines, which helps restore normal digestion. Research on shelter kittens, a population especially vulnerable to intestinal illness, found that preventive probiotic supplementation decreased the incidence of diarrhea.
Look for probiotic supplements formulated specifically for cats, available as powders, pastes, or chews at most pet stores. Human probiotics aren’t appropriate because they contain different bacterial strains at different concentrations. Sprinkle the recommended amount on top of the bland diet or mix it in.
What Not to Feed
Dairy products are a common mistake. Most adult cats are lactose intolerant, and milk or cheese will make diarrhea worse. Avoid any rich, fatty, or heavily seasoned foods. Raw meat and raw eggs carry bacteria that can compound an already stressed digestive system. High-fiber cat treats and dry kibble are also too harsh during an active episode.
Unlike dogs, cats should not be fasted for extended periods. Going without food for even 24 hours can trigger a dangerous liver condition in cats called hepatic lipidosis, where the body starts breaking down fat stores faster than the liver can process them. If your cat refuses to eat entirely, that’s a reason to call your vet rather than wait it out.
When Diarrhea Keeps Coming Back
If your cat’s diarrhea clears up on a bland diet but returns whenever you reintroduce their regular food, a food sensitivity or allergy may be the underlying cause. The most common culprits in cats are proteins they’ve eaten repeatedly over time, including chicken, beef, fish, and dairy. Even small amounts of protein in carbohydrate ingredients like wheat or corn can trigger a reaction in sensitive cats.
The standard approach for suspected food allergies is a novel protein diet: a single protein source and a single carbohydrate source that your cat has never eaten before. Common novel proteins include venison, rabbit, and duck. The diet needs to be strictly followed for eight to twelve weeks, with no treats or table scraps containing other ingredients, to determine whether food is the trigger.
Another option is a hydrolyzed protein diet, available through veterinarians. These contain proteins that have been broken down into fragments so small that the immune system doesn’t recognize them as allergens. Both novel protein and hydrolyzed diets are also used for cats with inflammatory bowel disease, a chronic condition that causes recurring diarrhea, vomiting, and weight loss.
Signs That Need Veterinary Care
Most single episodes of mild diarrhea resolve with bland feeding within a day or two. But certain symptoms indicate something more than a simple dietary upset. Seek veterinary care promptly if your cat has severe or bloody diarrhea, or if loose stools persist for more than two days despite dietary changes. Vomiting alongside diarrhea, fever, weakness, abdominal pain, loss of appetite, or visible dehydration all point to a potentially serious underlying cause that home feeding alone won’t fix.
Kittens, senior cats, and cats with existing health conditions have less margin for error. They dehydrate faster and are more vulnerable to complications, so err on the side of getting them seen sooner rather than later.
