My kitten & cat have soft, runny poop. Coccidiosis or contagious?

Updated On September 23rd, 2025

Pet's info: Cat | Tonkinese | Male | neutered | 4 months and 23 days old | 5 lbs

We bought home a kitten about 3 months ago who has had soft poops that I think have progressively got worse. We have tried 3 types of food recommended by our vet and they havent helped Our 1 year old cat now also has runny poop. Is it possible they have Coccidiosis? Is there anything else they could possibly have that is contagious? There is no blood and they are not vomitting. They seem happy and healthy otherwise.

Yes, coccidiosis is indeed a fair possibility. there are also other intestinal parasites that could be the cause as well as viral or bacterial infections. i would recommend to start with a course of treatment for worms and coccidiosis first in order to try and rule that out.
