You wake up to that rhythmic, wet thumping sound. Every cat owner knows it. It’s the sound of a digestive disaster about to unfold on your favorite rug. Dealing with a cat who has the runs is exhausting, messy, and—honestly—pretty gross. But before you panic and rush to the emergency vet for a thousand-dollar bill, you should know that diarrhea in cats treatment naturally is often the first line of defense for mild cases.
I’ve seen people try everything from expensive boutique probiotics to literally feeding their cat cheese (please don’t do that). The reality is that feline digestion is a finicky beast. Their guts are shorter than ours, designed for high-protein, moisture-rich prey, and when things go sideways, they go sideways fast.
The 24-Hour Reset
First things first. Stop the food.
Seriously. If your cat is an adult and otherwise acting normal—meaning they aren't lethargic or hiding under the bed—withholding food for 12 to 24 hours can give the intestines a chance to rest. It’s like hitting the reset button on a glitchy computer. Think about it. If the gut is inflamed, shoving more "work" (food) into it just causes more irritation.
However, water is non-negotiable.
Dehydration kills cats faster than the diarrhea itself. If your cat won't drink, try offering some plain, unseasoned chicken broth. Make sure it has no onions or garlic, as those are toxic to felines. Some vets, like the well-known Dr. Karen Becker, often suggest that a short fast is the most natural way to let the body heal itself. But keep a close eye. If they stop drinking or start vomiting, the "natural" window has closed and you need a professional.
The Pumpkin Power Move
If you’ve spent any time in pet forums, you’ve heard about pumpkin. It sounds like an old wives' tale, doesn't it? Why would a desert-evolved carnivore need a giant orange squash to fix their stomach?
It’s all about the fiber.

Plain, canned pumpkin puree (NOT the pie mix with spices) contains soluble fiber. This stuff is magic. It absorbs excess water in the GI tract, which helps bulk up the stool. On the flip side, it can also help with constipation. It’s a bit of a biological paradox.
Start small. A teaspoon mixed into their usual food (once the fasting period is over) is usually enough. Some cats love the taste; others will look at you like you’re trying to poison them. If they refuse the pumpkin, you might have to get creative with some plain, boiled turkey.
Why fiber isn't always the answer
Don't overdo it. Too much fiber can actually cause gas and bloating, making your cat even more miserable. If the pumpkin doesn't show results within two sittings, move on. Your cat's gut microbiome might be too far out of whack for simple squash to fix.
Probiotics and the Microbiome
Cats have billions of bacteria living in their guts. When your cat eats a rogue housefly or sneaks a lick of your cereal milk, that bacterial balance gets flipped upside down. This is where probiotics come in.
You’ve probably seen FortiFlora at the vet’s office. It’s the industry standard, but it’s basically just one strain of bacteria (Enterococcus faecium) and some liver flavoring. If you want a more robust diarrhea in cats treatment naturally, look for multi-strain probiotics designed specifically for felines. S. boulardii is a specific type of yeast that has been shown in various studies to be incredibly effective at stopping acute diarrhea.
- Saccharomyces boulardii: This is a "probiotic yeast" that survives stomach acid.
- Bifidobacterium: Helps with overall gut immunity.
- Lactobacillus: Common, but sometimes less effective in cats than in humans.
I once knew a cat named Barnaby who had chronic "soft serve" issues for months. His owner started him on a high-quality feline probiotic and within a week, he was back to normal. It wasn't magic; it was just science.
Slippery Elm Bark: The Nature's Pepto
If the gut is "angry" and inflamed, slippery elm bark is a literal lifesaver. This herb contains mucilage. When it gets wet, it turns into a slippery gel that coats the lining of the stomach and intestines.

It acts like a bandage for the inside of the cat.
You can buy it in powder form at most health food stores. Mix a tiny pinch with some water to make a slurry, then mix that into their food. It’s soothing, it reduces inflammation, and it’s generally very safe. Just be aware that because it coats the gut, it can interfere with the absorption of other medications. If your cat is on heart meds or thyroid pills, give the slippery elm at least two hours before or after the meds.
Bone Broth vs. Plain Water
We talked about dehydration earlier. It’s the silent killer in feline digestive issues. Most cats are already chronically dehydrated because they have a low thirst drive. When they have diarrhea, they are losing fluids at an alarming rate.
Enter bone broth.
Making your own is best because store-bought versions are loaded with sodium. Just simmer some chicken bones (no skin, no fat) in water for 24 hours with a splash of apple cider vinegar to pull out the minerals. It’s packed with glycine, which helps repair the gut lining, and it tastes like a five-star meal to a cat.
When "Natural" Isn't Enough
I have to be honest with you. Sometimes, a natural approach is like bringing a knife to a gunfight. If your cat has a heavy load of Giardia or Coccidia (tiny parasites), no amount of pumpkin is going to fix that.

- Blood in the stool (bright red or black/tarry).
- Vomiting along with the diarrhea.
- Your cat is a kitten or a very senior cat.
- The diarrhea lasts longer than 48 hours despite your efforts.
Cats are masters at hiding pain. By the time they look sick, they are usually really sick. Trust your gut. If your cat is hiding in a closet or hasn't moved in hours, put them in the carrier and go.
Diet Transitions and Food Sensitivities
Sometimes the "natural" fix is just changing what they eat daily. Many commercial cat foods are packed with fillers like corn, soy, and wheat. Cats aren't meant to eat those. They are "obligate carnivores."
If your cat has intermittent diarrhea, they might have a food sensitivity. Try a novel protein diet. If they usually eat chicken, try rabbit or venison. It sounds fancy, but it can stop the inflammatory response in its tracks. Also, keep an eye on carrageenan—a thickening agent found in many canned foods. Some studies suggest it can cause significant intestinal inflammation in sensitive pets.
Actionable Steps for Today
If you’re staring at a litter box disaster right now, here is exactly what to do.
First, remove all food for the next 12 hours to let the system calm down. Ensure there is plenty of fresh, filtered water available. If you have some plain chicken breast in the freezer, boil it until it’s bland and shredded—this will be their first meal back.
Second, head to the store and grab plain canned pumpkin (not pie filling!) and perhaps some Slippery Elm powder if you can find it. Start with a 1/4 teaspoon of the pumpkin mixed into that shredded chicken once the fasting period is over.
Third, monitor the litter box. Keep a log. It sounds weird, but knowing the frequency and consistency helps a vet immensely if you do end up needing an appointment. If things don't improve by tomorrow morning, or if your cat seems to lose their spark, it’s time to call the professional. Natural remedies are fantastic for minor upsets, but they aren't a substitute for a vet when a serious infection or blockage is involved.
Check the labels on your current cat food too. If the first three ingredients aren't clearly named meats, that might be your long-term culprit. Switching to a high-protein, grain-free wet food often solves "mystery" diarrhea within just a few days.
Stick to the basics: rest, hydration, and gentle fiber. Most of the time, nature knows what it's doing.
