Sherby does lotsa funny things. He likes to throw things off his cage. if you put a toy up there he will throw it off. If you pick it up and put it back he'll continue to do the same things for a long time. he'll also climb on top of his cage and pull his swing off to listen to it crash to the bottom. He used to wear his bell as a hat (I think there are pics of that in the gallery). My latest favorite antic is sherby will he will bob his head up and down and say "sherbysherbysherbysherbysherby..."
Ditto hasn't developed as many quirks yet, but we've only had her since march. I'm sure she'll have her moments.
