It seems that when it comes to choosing a gender for pet rats, rat balls can be a deciding factor. When I brought home my first pair of bucks my roommate noticed their large genitals and asked,"Is that its butt?" Her eyes widened in surprise when I told her it was his family jewels. When I asked another rat owner why she chose girls over boys she stated that the balls were a turn off. In my opinion, they aren't that large. Maybe an inch and a half long, but that's an inch an a half more to love. When rat boys are juveniles the rat to nut sack ratio is small, but I assure you they grow into their genitals and you'll hardly notice it.
When you get passed the balls, you'll see how amazing bucks are as snuggle buddies. My Dewey, big blue dumbo male sweetie, will walk up to me and place his head onto my hand for attention. I pet him until he falls asleep. I am currently fostering a female rat, and she doesn't show much interest in me. When I pick her up for pets, she will quickly scuttle away. Definitely something I never experienced with my boys.
