We read that rats were better and as she got bigger she would out grow mice, so thought it would be best to try to make the switch early. Our other BP has always been on F/T rats. We are going to try the scenting and spacing out attempts. If it is better to just stick to the F/T mice (since she does eat those) instead of sticking with rats till we can get her switched to the F/T rats we can try that too.
Just a thought, maybe we should get her F/T adult mice and just store them with Jasper's frozen rats, maybe that might work to help her switch?
