LOL! Wait 'til they start stinking up the house....then they might be a little easier to freeze. :wink:
Seriously...I ended up with a pair of live mice that the snake wouldn't eat and I had to make myself take them back to the petstore before I went and got attached to them! I don't think I'd have too much trouble euthanizing the young ones, but I'm sure I would grow attached to the breeders. Whatever type of critter it was. (Mice, rats, gerbils, etc)
