Ok, I've uploaded a photo, but it may take a while to appear. One or two "bumps" appeared on Biff's back a couple of days ago, but tonight they have apeeared ALL OVER his body and legs. When I say "bumps", I can't be sure if they are actually raised skin, or just fur. I know this sounds strange but really it looks like tufts of hair sticking up all over the place. We haven't changed his food recently, not shampooed him for ages, not used any unusual household cleaning products. Biff is totally unaffected by them, not itching or off his food or lethargic at all, but they are so scarey looking! Anyone had something similar?
