Honestly, the best way to switch them is to throw the rat in there and let them do the rest. No sense in sweating over a problem until it is one. While some BPs are life long mousers, the vast majority will wreck an appropriate sized rat with no issues. Personally I think most feeder rats have more of a scent to them than most feeder mice, and I find that stimulates the feeding response and has them smacking the dog snot out of them in no time flat.
