I actually bought my f/t mice from petsmart as well. I bought 3 small mice and 1 medium (just incase the smalls r 2 small for him). I tried feeding him today, and oh god did the mouse smell disgusting. Like i've smelt dead mice before. But this one was another deal. Im pretty sure its because it was cut in half. I dont think thats what is supposed to happen. Ill see once i try to feed him in a week or so.
