She has a sore on her haunch maybe half a centimeter in size. We've taken her to the vet a couple times about it. The last time we went they put a cast on her and gave us a topical antibiotic treatment. Also, we've had a cone on her head for about 3+ months. She's an indoor cat.
We've been using the antibiotic treatment... polysporin as well, hoping that it will help it heal faster. We can't get a gauze on her leg to keep it covered (she shakes it right off). Every day she scratches the scab off with her cone, and it bleeds. I've put tape on her cone to cover the parts that would scratch it off but she still scrapes it off!
It's been many many months! I'll take her to the vet again but I'm hoping for some more ideas from here.
