Sicy do you know anything about feline acne or how to treat it? I think Posh has it because although her little bald spot seems to be clearing up, she now has a new area of black spots on her chin by her bottom lip. I've been wiping it with a warm cloth (the black stuff seems like tiny clumps of dirt, it comes right out when it gets wet) and then wiping the area once-over with some antiseptic/antibiotic liquid. It doesn't seem to bother her at all; I've never seen her scratch this area. I'm not sure whether it's serious enough for a vet visit. I read one of the factors can be stress and there's nothing more stressful for her than the vet!
