If he sees these cute little fluffy babies hopping around, i think he'd change his mind. Besdies, you can train them. They are less smelly than hamsters (very clean if you keep up with their cage), and scientifically proven to be smarter than a 2 year old human child. And they will LOVE you back as one of their own.
I need to get some pictures together of the babies and slap them up somewhere. I have some archives of pictures of them when they were wee, but no recent ones, and nothing very well organised. But my cam sux0rs and work beckons.
I'd put some pictures of me in my little folder but i hate them all right now.
and while i am not averse to rat babies my roomie would probably object
thank you for thinking of me
