I have a kitten about 6 weeks old who I've just discovered has lost the hair around his mouth and under his chin. He was just at the vet for his shots and a checkup and they didnt notice, because it looked like he just had food on his face. He is on Albon for coccidia, and I was wondering if that could have caused the baldness. Any ideas? I can take him back to the vet tomorrow, but I want to know how urgent it us and if I should keep him away from my other kitten.
