I was doing some shopping for feeders at my local pet store and something came up that I had not thought about before. I had called prior to going to the pet store asking if they had frozen fuzzy mice, and I told them I would only need 3 or 4 and they said they had enough. I got to the store and asked for the girl there for fuzzies and they said they only had one, but she offered to sell me live fuzzies at the same price. I don't feed live, so I opted out of it, and I said I felt guilty seeing it die, then she said I could kill it myself, and I asked how, and she said by putting it in the freezer...

I've done as much research as I can on the subject and found out very little on how often this kind of thing occurs and whether it is cruel or not. So...

For you breeders out there, how do you euthanize your rodents, the pinkies and fuzzies at least? Do you freeze them or use CO2 or do you feed them or get sell them off while they're still alive?
For those of you who buy them, how does your source of rodents euthanize the pinkies and fuzzies? Freezing, CO2, or are you unsure, or do you feed them live?
