I am taking my piggie to the vet this Saturday, but I just wanted to know what's going on. I found and keep finding a few clumps of hair (not big - all except for one were only a few hairs) connected together by some sort of crust. It seems they fell out together like that (they were still attached when I found them). There are no visible places where hair is missing on the piggie herself. I think I may see small white bugs on her, but then they just appear to be bedding dust. Am I imagining things? Is this normal? What could it be?
