I bought this for my winter white dwarf hamster and I love how customizable it is! I like to change up his environment every now and then because it keeps him entertained. This cage is cool because the platform can be adjusted to any height, which means if your hamster can make it up the steep incline you can put the platform at the very top of the cage if you really wanted to! The bar spacing is great, definitely not worried about him escaping. Super easy to clean. Oh, and bonus is that it's the perfect amount of space for my little hammie to run around!! He's very happy, and so am I.
