When can my cat with ringworm come out of isolation after treatment?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 3 months and 2 days old | 3 lbs

Ok- my cat has ringworm- and still not 100% sure it is, (nothing lights up under black light), I have started a ketoconazole shampoo twice a week and spot treating with antifungal cream. I am keeping her in a bathroom by herself (heartbreaking), and cleaning her bedding and the whole bathroom once a day. She is tiny, less than 3 lbs so the vet wouldn't prescribe an oral Med. My question is how long do I have to keep her locked up away from us and my two girls. It is so hard to keep her away!

I've found that if you wash your hands after handling Sierra and do not have any open wounds it is uncommon to catch this from her. Since you've treated her and are giving the medicated baths she should be even less likely to spread Ringworm. Follow your veterinarian's advice on treatment but if she's been treated now for two weeks or more she should be safe to handle.

    As long as you wash your hands after handling Sierra and you do not have cuts or sores you should be fine at this point to let her out. Continue the treatments as directed. As Sierra grows up she will have better immunity and will get over this soon. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Sierra.
