that rat is to young to sex yet, when it is a few weeks old you put presure on the lower part of its stomach and a male of course will have an outie a female of course has an innie, my husband raises mice and rats for his snakes. hope this helps
i handle my tort alot, I read that it is not good for her...but I dont want her to bite when she gets big.
my husband made her a playpen of grass outside and her profile pic is how a set up her cage this weekend. She eats like a pig also. I am glad I found this forum. :)
