I have 2 big males that were eating small live rats for the breeders but wont take anything but mice. I am probably going to have to start a small mouse colony. I am not having any luck with the rats though. I had 2 ladies in with the male for about 10 days until I could get my rack built and they havent gained any weight... I am gonna give it one more week and then try pairing again.... Sorry a little off topic!![]()
