If it helps, here's what I do....
- In the morning I put all the mice/rats in a gallon ziplock.
- Before I start dinner, I put warm water into my feeder bowl and put the mice/rats in.
- After dinner, pour out the water and replace it with fresh warm water and then I go feed the snakes.
I've never had one "bust" on me. My previous mice came from Rodent Pro and my rats I got from Charles Cardell of Cider Reptiles & Rodents.
