It is 3:00 AM. You’re jolted awake by that rhythmic, wet "hork-hork" sound emanating from the foot of the bed. Before you can even find your slippers, it’s done. Your cat has left a puddle of bile on the rug, and a quick check of the litter box reveals a situation that can only be described as "liquiform." Panic sets in. You start Googling cat vomiting and diarrhea home remedies because you really don't want to pay a $400 emergency vet fee if it’s just a hairball or a stolen piece of ham.
But here is the thing. Cats are biological enigmas. They hide pain like it’s a professional sport. While a dog might act like the world is ending over a broken toenail, a cat will purr through a kidney infection. When both ends are "leaking," you’re playing a high-stakes game of "Is this a Tuesday tummy ache or a life-threatening blockage?"
The First Rule of the GI Upset Club: Stop the Food
Honestly, the most effective of all cat vomiting and diarrhea home remedies isn't a magical herb or a fancy broth. It is literally doing nothing. Or rather, feeding nothing. Vets often suggest a 12 to 24-hour fast for adult cats—but and this is a huge but—never do this with kittens or cats with known hepatic lipidosis (fatty liver disease) risks.
If a cat stops eating, their liver starts processing body fat for energy. If they are overweight, that fat can clog the liver quickly. So, if your cat is a bit "chonky," keep the fast short. Maybe six hours. The goal here is simple: give the gut a break. If the lining of the stomach is inflamed (gastritis) or the intestines are cramping (enteritis), shoving more kibble down the pipe is like trying to put out a fire with gasoline. It just irritates the system further.
The Pumpkin Myth and the Rice Reality
Everyone tells you to use pumpkin. You’ve seen it on every forum from Reddit to Quora. Pureed pumpkin (not the pie mix with the nutmeg and sugar, for heaven’s sake) is high in soluble fiber. In theory, it absorbs excess water in the intestines to firm up diarrhea. It also adds bulk to help with constipation.
Does it work? Kinda.

The problem is that most cats think pumpkin tastes like wet cardboard. If your cat is already feeling nauseous, forcing a tablespoon of orange goo into their mouth might just trigger another round of vomiting. If they'll eat it voluntarily, great. Mix a teaspoon into their wet food once you start reintroducing meals.
And then there is rice. We do the "chicken and rice" thing for dogs constantly. For cats? Not so much. Cats are obligate carnivores. They lack the high levels of amylase needed to break down heavy starches efficiently. Rice is mostly a filler that might actually make some cats more bloated. Stick to the protein.
The "Bland Diet" Hierarchy
When the vomiting has stopped for at least 12 hours, you can't just go back to the crunchy bits. You need the feline version of saltines and ginger ale.
- Boiled Chicken Breast: No skin. No bones. Absolutely no garlic or onion powder (those are toxic, they literally destroy feline red blood cells). Just shredded, plain, rubbery chicken.
- Meat-Only Baby Food: Look for Stage 1 Turkey or Chicken. Check the label twice. If it says "onion" or "broth" that contains seasonings, put it back. This stuff is like kitty crack; even a sick cat usually can't resist it.
- Low-Sodium Chicken Broth: This is more for hydration than nutrition. Ensure it is "pet-safe" or made at home without salt.
Hydration is the Real Battle
Dehydration kills cats faster than the actual upset stomach does. If your cat's skin stays up in a "tent" when you pinch it at the scruff, or if their gums feel tacky and dry instead of slippery, you are in the danger zone.
One of the best cat vomiting and diarrhea home remedies for hydration is tuna water. Not the oil, the water from the can. Use it to flavor their water bowl. Some people swear by Pedialyte (unflavored only), but some vets, like those at the Cornell Feline Health Center, warn that the electrolyte balance in human pediatric drinks isn't quite right for the unique physiology of a cat. Use it sparingly, or better yet, use HydraCare or similar feline-specific rehydration fluids.

Probiotics: The Good Bacteria Brigade
If the diarrhea is the main event and the vomiting has subsided, the microbiome is likely a mess. The "bad" bacteria like Clostridium have taken over because the "good" guys got flushed out.
Enter FortiFlora or Proviable. These aren't exactly "home" remedies you find in your pantry, but they are things you should keep in your kitty first aid kit. They contain Enterococcus faecium, which is basically the Delta Force of gut bacteria. It helps reset the intestinal pH.
What You Must Never, Ever Use
I cannot stress this enough: Do not give your cat Pepto-Bismol or Kaopectate unless it is a very specific, modern formula your vet approved. Old-school versions of these meds contain salicylates (aspirin). Cats cannot metabolize salicylates. You could literally cause their blood to stop clotting or give them a fatal stomach ulcer while trying to fix a simple case of the runs.
Similarly, Loperamide (Imodium) is risky. It can cause excitatory behavior in cats and mask the symptoms of a much more serious problem, like an obstruction.
When Home Remedies Fail: The Red Flags
You aren't a vet. I'm not your vet. Sometimes, cat vomiting and diarrhea home remedies are just putting a band-aid on a bullet wound. You need to stop the "DIY" approach and get to a clinic if you see:

- Blood: Bright red is scary, but black, tarry stool (melena) is worse. It means there is digested blood from the upper GI tract.
- Frequency: If they are vomiting every hour, they will dehydrate before morning.
- Lethargy: If your cat is "hiding" or won't react to their favorite toy.
- Pain: If they growl or hiss when you touch their belly.
- The "String" Factor: If you see a piece of yarn or tinsel hanging out of either end, do not pull it. This is a linear foreign body. Pulling it can saw through the intestines like a cheese wire. This is an immediate surgical emergency.
Why Is This Happening Anyway?
Sometimes it’s a "dietary indiscretion"—the polite vet term for your cat eating a spider or licking a greasy pan. Other times, it’s a change in kibble brand that was too abrupt. You should always transition food over 7-10 days.
However, chronic issues might point toward IBD (Inflammatory Bowel Disease) or even lymphoma. If your cat has a "sensitive stomach" every other week, it’s not just "something they ate." It is a chronic inflammatory state that needs more than just boiled chicken.
The reality is that cat vomiting and diarrhea home remedies are best suited for the "one-off" upset. Maybe they got into the catnip too hard. Maybe they had a stressful move. But if the symptoms persist past 24 hours, the "wait and see" method becomes "wait and regret."
Actionable Next Steps for Feline Recovery
If your cat is currently stable but symptomatic, follow this protocol:
- Remove all food for the next 6 to 8 hours to let the stomach settle.
- Test for dehydration by checking gum moisture and skin elasticity every few hours.
- Offer small amounts of liquid (tuna water or plain chicken broth) in a shallow bowl.
- Introduce a bland protein like boiled chicken or meat-only baby food in teaspoon-sized portions.
- Monitor the litter box for any signs of improvement or the appearance of blood/parasites (like "grains of rice" which indicate tapeworms).
- Schedule a non-emergency vet visit if the symptoms disappear but the cat remains dull or loses weight over the next week.
Keeping a log of what your cat ate and when the symptoms occurred will be the most valuable thing you can hand to a vet if the situation doesn't resolve at home. Sometimes the best remedy is simply being an observant, cautious owner.
