I've had pet rats for a while, they're pretty good. kind of like little dogs in behaviour.

I started breeding them for feeders a while back... Kinda feels bad when you turn on the gas, but I know they're having a nice uh.. "free range" (err, big fun cage as opposed to tiny rack bin) life, and being put down humanely, so it doesn't bother me too too much.

Besides - If i didn't do it, I'd never get to see the pups at all. They're pretty bloody cute though.
