My ball is 3'3 long. I've been feeding him with 2 large mice in one sitting every 7 days. This past weekend offered 3 and he ate them also in one sitting ! Is this ok for his size or he is getting overfeed ? When I brought him home, he didn't eat for a month, but now he is eating like crazy ! I don't want to offer him rats, because he only takes live, and rats tend to bite to defend themselves. So I'm ok with mice, but maybe he needs bigger prey.
