My males are huge compared to my females. I have 3 and 2 of them are well over a year old and the third just fathered his first batch.
I'd love to put them together. Any suggestions on how I should introduce them? I suppose I should also note that I don't handle mine with the exception of cleaning the cages and that's a quick lift from one cage to the next.
In addition to the males I have at least 12 breeder females. I got nailed by a couple of females and now I'm scared. I'd love to make friends with them because I do love them and want them to have a good life but I really don't know how to socialize with them and the bites I got really hurt and bled a lot.
Also, how do you know when a rat is depressed?
