UPDATE!!! I went back to the store and got a live rat fuzzy. It took about 4 seconds and he snatched it up. First time eating after 3 tries. I am pretty happy. I had a feeling he was hungry but he refused to eat mice and only wanted rats. I felt a little bad for the rat cause the little thing squealed but after I saw Cody pushing it down, I didn't feel bad any more. The guy at the store also gave me some of the substrate they kept the rats in, so I'm gonna try to thaw my frozen mice that I have left over in that substrate to finish these mice. Happy day.
