My cat has cat flu & conjunctivitis. Keep him in? Is it contagious?

Updated On September 23rd, 2025

Pet's info: Cat | British Shorthair | Male | neutered | 8 years and 3 months old

Hi. My cat had a closed eye that was weeping for more than 24hours. He has been to a vets today who diagnosed mild cat flu and severe conjunctivitis. He has had antibiotic and pain relief injections and we have drops for his eye. He likes to go out, should we keep him in for a few days and could our other cat catch it? Should have asked at the vets but we were more concerned with making sure Fui was comfortable. Thanks.

Yes, it's best to keep him in and isolated from your cat while he gets over the infection. These infections are quite easily spread from one cat to the other and it's very difficult to prevent transmission in the same household; but you can try to isolate the sick cat away from your healthy one for at-least one week after the infection appears to have resolved. They spread it through nose-to-nose contact, so avoiding this is most important for avoiding transmission. I hope that help and FuiFui gets well soon.
