Oh good heavens there's no way I would try to hand feed him the way he goes after his food! Hahaha. I have some long tongs I use, but even with those reaching into the cage was a little dicey, he can rise up and strike well past the top of his tank, and it's a 40 gal breeder! Especially when he's hungry.
I've given him p/k rat pups and he takes them with abandon, so I don't think it's mouse/rat problem. Given how easily he could distinguish between the live mouse and the p/k rat pup even after thawed in the mouse cage and warmed up with a hair dryer I think there's something else he's triggering on that I'm missing. Hrrrrmmmm......
