📝 Summary

Diarrhea is soft to watery stool. If your cat has diarrhea, you may see blood, mucus, parasites or foreign material in the stool. Here is a detailed look at the symptoms.

1 Overview

My cat has diarrhea, what do I do? Not all diarrhea needs treatment; it usually self-heals. For home care, don’t over-fast; ensure fresh water to avoid dehydration. Go to the vet if:

● Diarrhea not gone in 24 hours

● Cat is old, young, or has an underlying health condition

● Shows lethargy, depression or pain

● Is vomiting

● Diarrhea is watery, explosive or persistent

● Blood or very dark stool

What causes cat diarrhea?

Diarrhea is common with many causes. Severity depends on its features; cats diarrhea less than dogs as they’re pickier eaters. Common causes: parasites, infections, colitis. Cats may diarrhea from inappropriate products (non-food) or intolerance (such as lactose).

How to treat cat diarrhea?

Initial treatment controls symptoms: antiparasitic, antidiarrheal, sometimes antibiotics. Severe dehydration may need fluids (subcutaneous most common). Don’t over-fast — it blocks gut healing and causes hepatic lipidosis (fatty liver), a serious, potentially life-threatening liver disease.

Keep a consistent diet and minimize exposure to diarrhea triggers — the best prevention.
