2 New female rats

I got 2 breeders from my lady friend and I'm going to get a male next week and they dont really stink they seem happy and everything I was going to clean every week you think I should do it more? and should I put the male in there with both or put a female with the male for a few days and then the other female a week or so later? Thank's!

A week seems to work fine for me, but I've kinda gotten used to the smell. :oops: Both females in with the male is a-ok, you need to leave them in for a while anyways to ensure the female goes into heat and the male gets the deed done.
