What kind of snakes do you keep? Wild-caught Retics? Anyway, this situation doesn't matter with my Checkered Garter b/c his head is too small to get anywhere (that's why I feed him invertabrates), but I thought this could be a problem with the Hognose I'm getting in November. Basically I should put the mouse in the cage with tweezers and there's nothing else to worry about, right?
