1st of all, that is perfectly normal for him to claw at the glass, mine is just a bit bigger and does it every day. sometimes just harmlessly and othertimes he jumps strait into the glass to attk his reflection. usualy when i take his out he stops clawing at it 4 the day so it could be that. and he is big enough to run around a bit, i let mine raom my room while i watch and he loves exploring every little corner
rnt they just so cute!?!?!?!?
