I've had frogs, fish, and crabs as class pets and am kind of tired of doing the whole aquarium thing. So I'm thinking about getting a hamster or guinea pig for next year. Anyone have one in their Kinder class? Pros/cons? I'm leaning more towards a hamster because I have a ton of hamster stuff (cages, wheels, tunnels, etc) from me and my hubby's old hamster. Thanks!
