This is hotelvoodoo's manslave by the way
Isabelle just ate a mouse that I jiggled a little then dropped next to the door of her hide in her tub. She was completely inside her tub at that time.
I think letting the mice do their final few minutes of defrost near the enclosures helped.
The rest of the snakes all have a mouse inside their cages. Corena is cuddling hers like a bedtime teddy bear, but not trying to eat it at all. The others seem to be oblivious. I will just leave them like that til morning and hope to see no sign of mice in the cages!
Thanks for the help so far everyone.
