I am coming up on his second feeding and I really want to get him started on what fits me and him best. I have read so much back and forth I am thinking about feeding him hamsters..jk..pet store was feeding him out of a brown paper bag I have no problem with that he fed like a champ his first time. he did eat a live mouse....are rats better/? and if I do feed him rats I should probably pre kill or f/t... if you pre kill and he doesn't eat can you freeze it?
