It happens. You walk into the kitchen and there it is—a puddle where a puddle shouldn't be. Or maybe the litter box smells like a crime scene. Dealing with a cat that has the runs is stressful, messy, and honestly, kinda gross. You’re standing there with a roll of paper towels wondering what can i give a cat for diarrhea to make it stop right now.
Before you raid your own medicine cabinet, stop. Cats aren't small humans. Their livers are weird, their metabolisms are touchy, and things that help us can actually be toxic to them.

The First Rule: Put Down the Pepto
Most people's first instinct is to grab a bottle of Pepto-Bismol or Kaopectate. Please, don't. Modern formulations of these drugs often contain bismuth subsalicylate. Salicylates are chemically related to aspirin. Cats are notoriously bad at processing salicylates, and giving them these over-the-counter human meds can lead to salicylate poisoning. It’s a scary situation involving gastric ulcers and potential liver failure.
You want to help, not head to the emergency vet at 3:00 AM.
Instead of reaching for the pink stuff, we need to look at why the pipes are leaky. Is it a new brand of kibble? Did they eat a spider? Or is it something more sinister like Giardia? If your cat is acting totally normal otherwise—playing, purring, and not vomiting—you might be able to manage this at home for a day or two. But if they're lethargic or hiding, skip the home remedies and call the vet.
What Can I Give a Cat for Diarrhea Right Now?
If the situation is mild, the most effective thing you can do is actually nothing. Well, sort of.
Bland diets are the gold standard for a reason. When the intestines are inflamed, they need a break from processing complex proteins and fats found in standard cat food. Many vets, including those at the Cornell Feline Health Center, suggest a temporary switch to boiled chicken breast. No skin. No bones. Definitely no salt or seasoning. Just the meat, shredded up.
Some people swear by adding a little white rice. Honestly? Most cats hate rice. They’re obligate carnivores, and their bodies aren't great at digesting grains anyway. If they'll eat it, a tiny bit of plain, overcooked white rice mixed with chicken can help bind things, but the chicken is the star of the show here.
The Magic of Plain Pumpkin
You’ve probably seen this advice on every pet forum on the internet. It sounds like an old wives' tale, but it actually works. Plain canned pumpkin (NOT pumpkin pie filling—that stuff has sugar and spices that will make the diarrhea way worse) is packed with soluble fiber.
Soluble fiber acts like a sponge. It absorbs excess water in the gut, which helps firm up the stool. It also slows down "transit time," meaning the food stays in the digestive tract a bit longer so the body can actually process it.
Start small. A teaspoon mixed into their food twice a day is usually plenty. Most cats actually like the taste. If they're picky, you might have to smear it on a paw so they lick it off.

Probiotics and the Microbiome
Inside your cat’s gut is a tiny, complex ecosystem of bacteria. When diarrhea hits, that ecosystem is basically undergoing a natural disaster. The "bad" bacteria are winning. To tip the scales back, you can use a high-quality feline-specific probiotic.
Products like FortiFlora (by Purina) or Pro-Pectalin are staples in the veterinary world. They contain Enterococcus faecium, a bacteria that helps stabilize the gut. These aren't overnight miracles, but they definitely speed up recovery. Don't bother with human probiotics or yogurt; the bacterial strains we need are different from what a cat needs, and many cats are lactose intolerant, meaning yogurt could actually trigger more diarrhea.
When Home Remedies Aren't Enough
Sometimes, no amount of pumpkin is going to fix the issue. You need to know when the "wait and see" approach becomes dangerous.
Dehydration is the real killer.
Check your cat’s gums. They should be pink and slimy. If they feel tacky or dry to the touch, your cat is dehydrated. You can also try the "skin tent" test. Gently pinch the skin between their shoulder blades and let go. It should snap back instantly. If it stays in a tent shape or sinks back slowly, get to a vet. They likely need subcutaneous fluids.
The Parasite Problem
If you've been wondering what can i give a cat for diarrhea and nothing is working, the culprit might be microscopic. Kittens, especially, are prone to roundworms, hookworms, and protozoa like Coccidia.
You can't see these with the naked eye. You'll need a vet to run a fecal flotation or a PCR panel. If it’s parasites, all the boiled chicken in the world won't help; you'll need specific medications like Fenbendazole or Metronidazole.

Metronidazole is an interesting one. It’s an antibiotic that also has anti-inflammatory properties specifically for the bowel. Vets prescribe it constantly for "garbage gut," but it requires a prescription and careful dosing because it can cause neurological side effects if given in excess.
Common Myths About Feline Diarrhea
Myth: Fasting your cat for 24 hours is good. Actually, this is old-school advice that's mostly fallen out of favor. While it gives the gut a rest, cats have a unique metabolism. If a cat—especially an overweight one—stops eating entirely, they are at risk for hepatic lipidosis (fatty liver disease). This can be fatal. It's usually better to offer small, frequent meals of a bland diet rather than withholding food entirely.
Myth: Milk helps settle the stomach.
Absolute no. Most adult cats lack the enzyme lactase. Giving a cat with diarrhea milk is like throwing gasoline on a fire.Myth: If there's blood, they're dying.
Seeing bright red blood in the litter box is terrifying. However, in many cases, it just means the lower colon is very irritated. It's called hematochezia. While it definitely warrants a vet visit, it’s often just a sign of severe inflammation rather than an internal hemorrhage. Dark, tarry stool (melena) is actually much more concerning as it indicates bleeding higher up in the digestive tract.
A Quick Word on Food Allergies
If your cat has chronic, intermittent "soft serve" stool, you might not be looking for a quick fix, but a lifestyle change. Many cats develop sensitivities to common proteins like chicken or beef.
In these cases, a "novel protein" diet or a hydrolyzed protein diet (where the proteins are broken down so small the immune system doesn't recognize them) can be a lifesaver. Brands like Royal Canin and Hill's Science Diet make prescription versions of these, but again, you'll need a vet to guide you through an elimination trial.
Actionable Next Steps for You and Your Cat
- Inspect the Evidence: Look at the stool. Is it liquid? Bloody? Does it look like it has grains of rice in it (tapeworms)? Note the color and consistency. Take a photo—your vet will actually appreciate it.
- Check the Vitals: Feel the ears and paws. Are they hot? Is the cat lethargic? Check the gum moisture.
- The 24-Hour Bland Test: Offer small amounts of plain, boiled chicken breast. If the cat won't eat or starts vomiting, stop and call the vet.
- Hydration Station: Ensure plenty of fresh water is available. You can even add a little bit of the chicken broth (from boiling the meat) to their water bowl to encourage drinking. Just make sure the broth has no onions or garlic, which are toxic.
- Fiber Boost: Add one teaspoon of plain canned pumpkin to the chicken.
- Cleanliness: Keep the litter box spotless. Diarrhea can cause "litter box aversion" because the cat associates the box with pain or discomfort.
If the diarrhea persists for more than 48 hours, or if you see a total loss of appetite, persistent vomiting, or extreme lethargy, stop the home treatments. A quick vet visit for a fecal exam and some professional-grade anti-diarrheal meds is much cheaper than an emergency stay for severe dehydration and electrolyte imbalance.
