My cat has had this scab on her foot for almost 2 months now. I pulled it off but it grew right back. It looks like a flat callus. The vet told me just to keep an eye on it but weren't really much help for what I had to pay them. I have hardwoos floors so I don't know if that could possible make a difference of how her feet are affected. She's a very active cat otherwise and it doesn't seem to bother her at all. Has anyone else's kitties had this problem?
