Before work, I throw all of the rats/mice in an empty tub in my rack so they are thawed/warmed by the heat tape. Normally, the smell of them thawing for 8+ hours will have the snakes just waiting for me to open the their tubs. I also use the hairdryer on the head to. Most of my breeders would probably take the rat frozen if I gave it to em, but thats not happening.
