Candace - the cage setup I have for the Robos is a large Gabber tank, I think
I got the cage with the Robos from Morag so she'll be able to give you more info on it, I'm sure you can get them in the US I guess it's just a case of tracking them down. They are really good, large so the Robos have plenty room to play, Molly's actually in one exactly the same, she had to be moved into one because of her constant bar biting causing her hair on her nose to go bald, poor girl.
nooboo - there are many treats that you can give your Syrian that I was unaware of, for example dry Ready Brek. The Syrians love it!
