i'm watching this adorable little guy for a friend, and possibly adopting him after (her schedule has grown too thick to continue watching him). while watching him, i noticed a few quirks. for one, he never ever ever balls up. he'll puff and puff. sticking his quills on end and giving signs for those he doesn't know (i.e. my brothers) to back off, but he won't ball up. he also never sits still once he's out of his cage (the above pictures are my only pictures of him sitting still- i'm serious), however once he's in his cage he burrows under my t-shirt and lies there until the lights go out or i wake him for some reason. I know he runs on his wheel at night because i hear it for sure, but i never see him on it. he always seems to jump off before i can catch a look. idunno, maybe they're all normal things. i'm just really worried. i'd hate it if the cute lil sweetie was sick somehow. thanks in advance!!
