I have some of those plastic "goldfish" bowls from Petsmart that I used to use when I bred fish. They were holding tanks or transfer tanks for my guppies (they get sucked up pretty quickly if you aren't paying attention). I saw no reason to throw them out when I stopped breeding fish.
So now I count out the number of mice I need, throw them in the fish bowls and run slightly hot water over them. Once the mice are in enough water to be able to move around, I turn on the hot water all the way and let it run, more than a trickle but less than what you need to wash your hands fully. This makes the water overflow into the sink, but because of the little lip on the bowls, the mice stay. After a few moments of letting the water agitate, I turn off the water and let the mice sit for five to ten minutes. I then pull out the pinkies and fuzzies, which are thawed and warm. I feed them off and while I'm doing so, the rest of the mice are usually 98% thawed. After I'm done feeding the pinkies and fuzzies, I run the hot water again to make the larger mice really hot and feed them off. I transfer all the snakes to 6qt tubs to eat, so I throw the mice in each tub then slowly get the snakes in their tubs. It takes a bit to feed this way, but they find the mice easier.
The only snake I don't feed in a 6qt is my black rat. He's too strong to keep in one, so I throw him in one of my extra 10 gallons.
And, for some reason I always end up one mouse short. I can count out the mice five times and even add an extra one "just in case". Always end up short. I think one of my cats is a mouse eater. Lol
