So I was given two female rats. I'm planning on breeding them and getting feeders...ect.

I was only planning on buying one male. But everything I've read says that rats are social and should be kept together. Should I buy two males then? I'm not planning on housing the male/s with the females all the time - just during the whoohaa period - so the male (if I only get one) will be on his own 90% of the time. Should I consider getting two? or will they fight and be mad and huffity and need to be separated?

Also - Because I've always wanted one, I'm planning on getting a hairless male, would it be a problem if I bought a furred male to be his cagemate?
