Cat-Care 
Intro If your cat has loose stools it can feel scary, but many cases are mild and manageable at home. This guide covers safe first steps for a cat with diarrhea, simple monitoring routines, and clear signs that mean you should contact a veterinarian. Keep calm, take notes, and use stepwise care rather than guessing causes.
One sentence answer Start with gentle home monitoring and hydration support; if diarrhea lasts beyond 24 hours, contains blood, or the cat becomes lethargic, seek veterinary care immediately.
Core principles
- Hydration first: replace fluids and monitor drinking and urine frequency.
- Reduce complexity: switch to bland, consistent food rather than new diets.
- Safe environment: keep litter clean and quiet rest areas to reduce stress.
- Monitor and record: track stool, appetite, weight, and behavior every 6–12 hours.
- Know limits: home care is for short, mild cases only.
New owner 14 day checklist Day 0–1: Observe and isolate minor triggers. Note when diarrhea started, recent treats, new food, or access to human garbage. Keep the cat indoors and limit stressors.
Day 1–2: Pause treats and food transitions. Offer small, frequent amounts of a bland, familiar diet or a vet-recommended GI diet if you already have one. Provide fresh water and consider multiple shallow water bowls.
Day 2–4: Track output. Record stool frequency, consistency, and color. Weigh the cat daily if possible. Look for dehydration signs: tacky gums, decreased skin elasticity, or reduced urine.
Day 4–7: Reintroduce normal food slowly if stools improve. Move from 90% bland to 75% then 50% of regular food across several meals. Continue to avoid new proteins or dairy.
Day 7–14: Review progress and persistent patterns. If diarrhea resolves, keep consistent feeding and avoid sudden diet changes for at least two more weeks. If mild flare-ups recur after introducing new food or treats, return to the bland diet and re-evaluate.
Ongoing risk prevention: maintain up-to-date parasite prevention and vaccinations, secure trash and toxic plants, and keep a calm routine with play, hunting-style feeding, and sleep areas. Always keep a simple log (time, stool description, appetite, behavior) for 14 days to show your vet if needed.

When to consult a vet Contact a veterinarian if diarrhea lasts more than 24 hours, contains blood or mucus, is paired with repeated vomiting, severe lethargy, fever, signs of dehydration, weight loss, painful abdomen, or if your cat is a kitten, elderly, or has preexisting illness.
