My Hedgehog Brock is almost 5-6 yrs old now, he has gone through gum growth removal and now 1 month ago he was treated for possibility for mites and staph infection. So he's doing fine now, but recently he's been chirping alot, so i've gotten worried since its while he sleeps (snoring maybe?)...

My baby lasts on her wheel for about an hour at a time. Rests. Then gets back on. Last night I woke up while she was running on her wheel and she was making a high pitch whistling sound. Sounded almost like a squeak. Should I be concerned? Is she tiring herself out too much? Or is this normal...
