My new hedgie is probably about 3 months old, maybe 2.5. When I brought him home, I noticed he scratches somewhat often at night, at least for a bit after he wakes up. He's still active, runs on his wheel, eating, pooping. I don't see any big bald spots, maybe a large thinner spot on his side, but definitely not bald. I haven't seen any moving things on my clothes or his fleece. Is he quilling or does he have mites?
