We do mostly venomous and feed live as much as possible to keep the venom cycling in and out of the snake. We do filter thru a few balls for the retail end and we also feed them live. I have always took the position of keeping the snake as close to natural as possible. If they are snake-eaters in the wild, we feed them snakes. I think the same applies here. They hunt and kill in the wild and I think it keeps them sharp and focused to allow them to kill in captivity.
