I bought this in the hope that it would keep my Cherry, a fat Syrian, more amused than a conventional cage. I was rather disappointed at the cheap feel to the entirety, and I was terrified of snapping the locks/clasps which are rather fragile. My hamster, like others, has also used the outside wheel as anything but an exercise area, flinging poo and splattering wee around to her heart's content; but maybe that's just her. The second level area has, after just a week, been practically chewed to nothing, and I may have to remove it in the near future. The accessories - the various add-ons and tubes etc - are VERY expensive, and are made of the same cheap, plastic. I bought a 10 inch tube and a 'bus' (yes, really!), and, to my horror and, no doubt, her delight, discovered her running round the kitchen work-top having managed to push out the bottle in the bus and wiggle free through the hole. This looked fabulous; upon receipt, I think a conventional cage with several levels may have proven a better buy.
