Ok thanks so much. I do want to switch him to rats but as he is used to live mice I thought I would switch him to f/t mice and then to rats in the next few feedings so as not to mame too huge of a change right off the bat. I thought he might be too stressed out to eat having just arrived, but I guess not!
I had read that "rat pup" kind of means a lot of different things to different people. To clarify, how many grams should his prey items be? Is it still ok give one to him even though he just had the fuzzy mouse (tiny as it is)?
