Was wondering how often I can (not need to) feed my juvenile ball. He is 9 months old and I don't have a weight but he is more plump than most that I have seen at 9 months. Been eating adult mice (live) but I want to switch to rats asap. Never turned down a meal, not even the day after I got him. Have been feeding him every 4-5 days. Last time I gave him 2 mice because he has outgrown them. Took both no problem. Also, are rats more dangerous than mice? Obviously rats are bigger but are they more likely to attack? I've herd horror stories about how viscous gerbils are when put in danger
