I have an extra fridge/freezer just for snake food. It contains mice, rats, frogs, guppies, lizards, and an albino pacific gophersnake that I found in the wild (dead on road). And worms in the fridge.

I have never had a problem putting down a rodent for snake food. But, I also never pet them or name them. I look at them as snake food from the day they are born- although I do make sure they are well taken care of, to a basic level anyways.
