This may be a silly question, but are there sometimes issues switching from mice to rats? I feed f/t and stores around me don't normally stock young rats. My young(ish) BP eats very well (thank god), but I recently found a rat breeder nearby that I was going to use once my current mouse supply runs out. I know rats are more nutritious and I would like to make a permanent switch.

After browsing countless threads, I got an inkling that problems have arisen from switching to rats? If I'm just getting paranoid, feel free to just say so! I just want nothing less than the best for Boomer. He is, afterall, my first ball. Thanks in advance!

just some background:
He is currently eating a large adult mouse every 5 days. He will attack and constrict about 3-10 seconds after sensing the mouse. If there is no problem, then I can't wait to switch and let everyone know how he does. If there sometimes is, he honestly probably wouldn't care and devour it anyways, but better safe than sorry I always say.
