Rats breed insanely. We have two pet male rats(well, my daughter does) and though they are super sweet pets, had I known they were stinky, I would not have allowed rats. The whole family really enjoys them though. Kinda like mini dogs.
I looked into neutering them,but, do to their age and size, the risk of them dying was very high. They say that helps with the stink.
I took photos of baby rats, they were brown rats, so, not as cute as the hairless ones, at least not photographically. the mom actually let the child borrow a male rat to breed with her female. Why, I don't know. Made neat pictures!
I need to take our rats to the studio and get photos of them.
