My cat Simba has developed two Bald patches. One is on her right back leg and the other is on her front right leg. These seem to have appeared over-night ??? She is an indoor British Blue. My partner and I have noticed that she has been cleaning herself more often than usual. The bald places are slightly red-ish, (but not an angry red) and possibly have bite marks, but I'm not sure. The only thing that's changed in her home is a pot of grass that the vet suggested we put in to help with her hairballs. We are taking her to the vets this weekend, but can anyone suggest what might be wrong Any help is very much appreciated.
