My hedgehog is 11 months old, and I've had him for about 4 months. I was just gone on a 4 day camping trip and left him in the care of my parents and little brothers. He's acting very docile, which isn't very unusual for him but he usually is a little more grumpy when I first wake him up. He's still pretty active - he crawled around on me when I picked him up. He isn't eating a lot, not even his mealworms. His skin is super flaky and when I gave him a bath last week I noticed he seemed to loose a lot of quills (8-10 that I saw). His nose is pretty dry - definitely not as wet as it usually is. His face is pretty clear - his ears aren't flaking and his eyes and nose look clear. Does anyone know what could be wrong with him?? What should I do? I'm really worried, please help!! Thank you!
