Put calm down first

Sometimes a transition takes a little time...so be prepared to work a bit. However, you could get lucky

It sounds like you have had a very good attempt at making a transition. I would just keep repeating what you are doing now. Make sure the rodent is warm and scent the area well....you should get it to take the f/t rodent eventually.

There are a couple other things that you could try, but I would just stick with this for a couple of weeks......then take some alternative methods.

....that is just how I would handle it. Maybe someone else could offer some additional options
