My kitten has watery, bloody poop & swollen anus. What should I do?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 3 lbs

My kitten is about 6 weeks old. His poop is extremely runny like water, some blood has came out and his Anus is swollen. Probably from straining. I switched his food back to wet bc the hard I feel like is what was causing it. When we got home to dah the watery ness is what we saw, didn’t smell like poop at all looked exactly like the color of his food. went and got some pumpkin and pedialite. But I’m still worried something is wrong.

A sudden change in diet can lead to diarrhea, even blood diarrhea. But it can also be caused by a GI illness or intestinal worms among other causes. Feed Boz a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.
