I know this has been asked many times but I wanted to clarify because I see multiple different ways. He is on live, 145 g. He refused a rat once first feeding, but is going well with the mice. I am planning on switching to rat after one more meal of mouse (Tell me if I need to feed mouse more before trying). Should I skip couple meals before I offer him rat? so he can be hungry? or does that come later? The place I get my feeder told me they can put the mouse litter/bedding and put a scent on the rat for me also. If he refuses to eat with doing everything, do I just keep trying rat every week? or every two weeks? or feed mice again for some feeding?

I've done research but I just want to know step by step rather than try this try that... and what to do after he refuses.
