I put mine in ziplocs, place them in ambient temp water fo about 1/2 hr, and then in warm water for another 1/2 hour. they usually thaw out with this process. after that i heat them up with blow dryer next to container where i keep the snakes, and that gets them real interested. my balls like them real hot so i blow dry them for about 5 minutes and then i just dangle them in front of them, they usually take it in 1.1 seconds flat.

The last couple of feedings my balls grab and constrict and then go into their hides, I take the rat pups out and heat them up again, they grab constrict and eat on the second offering, WHY? I dont know but they have been doing that the last couple of weeks.

hope this helps.

whatever you do, don't boil the rats!
