Sphynx skin problem - black spots
Hi all. I just bought two sphynx kittens (about 10 months old). The previous owner was not a good person, kittens are skinny like ****. Anyway, they look alright, clear eyes and nose, normal breathing, no cough, no sneezing, eat well (they are starving) etc. The problem is their skin. They are both covered in black spots of various form, everywhere, on the body, legs, tail, ears, head etc. The spots are just there, the cats behave normal so it seems the spots are not itchy etc.
Has anyone seen anything like this before? What could this be? What tests I should do and what could be a cream/pills I could use/consider using?
Any comments and experiences would be most appreciated.
