Haha the "zombie dance"
But you can do that or heat it up with a hair dryer. (once thawed)
Also try prescenting with the scent of the meal your feeding them. I use the bedding from my rat colony to precent the cages and while doing it I put the rats in a 6 qt or zip lock with some more bedding to make them smell exactly like the prescenting so what the snakes smell to entice them they are also eating.
A good way to tell if prescenting worked is if your snakes head is out of the hide and his tongue is going like crazy or if they are halfway out the hide in the kill mode.
But I would also recommend feeding in the tub/tank
