Actually, I did at first. I didn't want to kill them but I couldn't have imagined wanting rats as pets. I was more or less afraid of them, though I'd never really been around them. Mice, yes, Rats, no. When I first heard (via the internet, would ya believe?) that some people kept rats as pets, I was appalled. However, it also peaked my curiosity. Here and there, I'd go surfing, reading up on pet rats. I learned about their behavior traits and what the ate, their aggression level (which is virtually nil) and all. When I saw peoples pictures of them posted online, I had to admit to myself, hey, they ain't half bad. Then, dang, they're cute l'il buggers.
It took a mere evening after bringing two home from a trip down to visit my brother, to fall hook line and sinker for these gentle and beautiful darlings. I can't imagine my life without them, now.
