iv noticed since he's started eating again and been more active due to heat lamps he had been very aggressive...i wave my hand outside his cage, he come out looking curious, then *BAM* right against the glass. im in fear for my fingers! hes been off food for 5-7 weeks so im feeding him a little a day. will the food entering his system decrease aggression later on. Any ideas? im worried bout my fingers and checkers constant head banging. (he only does it when i wiggle things like my finger in front of the glass so i stopped doing it, but im still worried)
