Yes I find that with my hamsters - only the syrians chew the bars or plastic bits. Honey has nibbled all the corner out of her yellow platform on the hamster heaven and completely destroyed one of the green penthouses on the top so I had to buy another one.

I ordered an Imac from ebay last Sunday and he says he's sent it but I haven't got it yet. I don't know whether to order another from him but I want to see the first one before I do, or order from that other company that would probably be quicker as I can order today. I really need the cages ASAP.
