I thought it was unsafe to feed live mice due to risk of injury to the snake? That's what I have been told, maybe that's not true? They have both been on frozen mice since hatching. We have tried the tricks like warming them up and splitting them a bit so they are more obvious, and all of that. We haven't tried live yet though, I'll give it a try if she keeps eating sparsely. For the past few months it has been two mice per month for her.
