My guinea pig max seems to be part hedgehog. He always has a tuft of fur on his back in the same place. I have checked it for lumps and cant see anything, but he is always scratching it by wiggling by the side of his wood igloo.
Should I take him the vet? I am worried he may have a skin problem. I have tried to brush it down and it just sticks up again when he goes back to itching it.
Any advise?
