I feed frozen to all my animals except for a couple I'm trying to convert to frozen thawed. Not because I think feeding live is gross, or dangerous for the animal. The reason I don't feed live is it's less convenient for twelve snakes (I don't want to start a breeding colony) . Once I tried feeding live to my snakes that would stubbornly only eat live food, so I bought three hopper mice. They gave me fuzzies by mistake. I also ordered a live adult mouse for my pastel. They were in paper "chinese takeout" boxes. I left them in their overnight and when I woke up in he morning the boxes were CHEWED though (I should have known that would happen!!) The adult mouse was in the with babies but one was missing. I saw mouse organs littering the shavings and ya, that's what happened to third mouse. Not pretty.
