Just got back from Petco and looked at the sweetest itty bitty little guy...I know they don't stay small, but the employee there said they have fang like teeth and will bite. Is this true? Also she said their main diet is mice...is this true also? I posted another question in terrarium, vivarium etc. the other day and I havent gotten one answer back, maybe I put it in the wrong area but if someone could help me out with that one I would appreciate it too!
