My bee has the most aggressive feeding response of any ball I've seen. When there are F/T in the room he will literally strike at the tub wall for no reason. On more than one occasion he has hit the rat so hard as I open the tub that it breaks off the tail or foot and the feeder drops into the tub. This results in him completely unregistering the rat as food and hanging out of the tub striking in my general direction repeatedly. I have to use a paper towel tube to bonk him on the head gently and try to knock him out of it / push him back in the tub.
He has also struck so hard out of the tub that he launched himself over the lip and down to the floor.
Last week my pewter struck and coiled and only caught the tip of a foot. I just kept thinking 'catch a tiger by its toe'. Then the foot slipped out of her mouth and she just sat there with the body coiled and her mouth not clamped down on anything but holding her head like she was. It was pretty derpy...
