My male mixed breed has had a black colored chin for about the last 2 months or so. I have had him at my vet twice in the same time. He shaved hs chin, and said it was a "skin disorder" and gave him some penicillin to clear it up. It helped some what, but he still has the problem a month later. The vet really don't know what it is I think. I don't think it is an allergy because he eats mostly holistical food. He is 6 years old, and this disorder does not seem to effect him. It kinda comes and goes. Any clue what might be going on with my cat?
