Hehe aw that's cute!
That's lots of folks for you to look after, 3 hammies, an infant and your hubby :P
Yes, I think I'd find it hard to not have a hamster now. But I think that will change once I have a cat, firstly because they don't mix. I have, at one time, had a hamster (mine), a cat (my friend's) and a dog (my parents') in this 2 bedroom flat (plus kitchen, living room, bathroom and hall). Had the hamster in one bedroom, the cat in the other and the dog in the living room. Hehe. I wouldn't want to have to juggle that again. I would give the cat run of the house (when I get one) and would hate to shun the hamster to a room where the cat's not allowed.
