The mice were killed and frozen a week ago. So I highly doubt it's anything to do with the mice themselves. Irritates me too. My beautiful 2002's (from Jason Parrish) are eating 2 f/t pinks every 3 days with no problem.
It's funny, he acts REALLY interested, but no bite. I used to be able to place 3 f/t mice in the cage with him, and 30 minutes later, they'd be gone.
He is housed right above an adult female. But he's always been, no problem before. Odd. Maybe he's just being silly.
I didn't try giving him live. I actually had killed off my last batch of 50 (their were only about six left, so I figured I my as well have them frozen for the corns and get a new batch of lives for my balls, who will ONLY eat live, boogers) just the other week. Maybe in another 2 weeks I'll get another order of lives in, or just cave in and pick one up at a local pet store to try it, if he doesn't take, the balls will always take the extra snack. Only thing, I have no problem giving the balls live as long as I watch them, but they're pretty darn strong with their constricting, but I'm concerned with the strength of the corn. Wouldn't he be more likely to be harmed?
