My cat, who was a feral cat, has very little hair on her whole back end(innner thighs, outer thighs, lower belly and butt). I see no marks of any kind. I think that she is cleaning excessively. Is there a solution for this.
This is called excessive grooming. Allergies, anxiety, mange, fleas are just a few of the causes. There are meds available that may help. vetcare
