yeah, i like when they do that, they stay put and i figured they like it inside shirts and stuff cuz it's dark and warm!
oh, and in regards to getting bit, i don't think they would....... unless you had a rat running around in your shirt before hand.... heh
Actually, i've had that happen, i was handling a pet rat and it was crawling on the front of my shirt...... hours later I was holding one of my ball pythons and looked down to see her biting my shirt and trying to constrict it! oops! I put her back and fed her.... but now remember to always change my clothes!
