Hmm, yes, dogs and cats may need a bigger budget XD
There are some breeds that are hypoallergenic (or at least semi-), for dogs it would be breeds that have hair and not fur, so probably breeds like terriers, shih tsu I think, lhasa apso. With bigger dogs, go with bigger terriers XD Maybe there is more, I'm not sure. I can't think of cats besides the sphinx, but I know for sure there are some, I just can't get them from the top of my head ^^;
I'd die if I got an allergy to fur. I've heard and read that kids who are raised with dogs/cats are less likely to develop an allergy to them in the future.
But well, if you are too busy taking care of hamsters, which are very not demanding, then maybe bigger pets aren't a good idea right now

Althoguh cats.... are pretty self sufficient once they are bigger than a kitten
Edit: Ooh, can I have Punky eyes (Bright Berry) & Thetis Earrings (Fire Orange), Hunny Horns (Yellow), Guardian Of time Wings (Fire Orange)?
