Can also do this with a live rat, just ask for bedding from a mouses cage.

I've done it several times this way and usually take a rat with no scenting the following feeding or the 2nd time after.
I second trying to scent a F/T rat. We had one stubborn BP and thawing both a mouse and a rat in the same bag did the trick. I think we scented for two meals before trying without and he had no problems accepting the rat.
