Thanks for the suggestions, they were helpful. As far as cooling them...I considered it, but decided against it as I was having to medicate the female daily due to the tail amputation and they didn't have the weight I don't think.
Proud to announce that about two weeks ago though I tossed a a hopper in their cages and left them for a while (have tried this twice before with no real interest so the corn snake got a rare treat...live mice lol). About 10 minutes later I heard thrashing and cries from the mice...success! They have repeated this weekly now. I'd like to get them started on frozen/thawed as soon as possible though (it's easier on me and less distasteful to my girlfriend).
Just curious about how others have gone about this?
