We recently got two rescue cats, a mum of about 2 1/2 and her boy (about 1yr). The boy has a thin bald patch about 2inches long on his tail which he had when we got him three weeks ago. The man at the cattery said he thought he'd been overgrooming as a result of being in the small space for nearly 3 months.
I know three weeks isn't long, but when will it start to grow back? I haven't seen any improvement and I've never witnessed him excessively grooming anywhere - I'm at home during the day so I'm with both of the cats most of the time. They haven't been outside yet. He is very affectionate, full of energy, eats everything put in front of him and otherwise well.
If it's not overgrooming, any ideas what else it could be? It doesn't look sore or dry, just a bit bald! His tail is very thin, and one of the other members of staff at the rescue centre said she wondered if it was because he had been a bit malnourised when younger. (they were both rescued from a house that had become over-run with cats)His ears are quite baldy too if that means anything (he's had drops for earmites recently although it was his mum who was scratching but both were treated).
any advice much appreciated
