OK, do other peoples sphynx cats get what I call a cinnamon ring?? Mo always has a clean bottom, but sometimes if he's been hot he gets a brown ring round his bottom! It's not poo, but when hes been sweating and had his tail down all curled up sometimes he develops this dirty mark where it gets all dry and its impossible to clean off!!! It stays for a few days then clears up in time. But theres no getting that mark off! He is always licking himself and I've tried putting him in the bath, wet wipes, creams. Only thing I havn't tried is coconut oil. Will coconut oil sort this problem out? I am planning on ordering some on friday when I get paid.
