Yes that's the Mickey 2XL. The original blue base got broken when we moved house so I found a replacement base which is grey
The bar spacing is 7mm on it. Small enough to prevent mice getting in and robos getting out ha ha. I have a Syrian in it at the moment but he has grown very large so will need to be upgraded. You might be able to get the Hamster Heaven cheaper somewhere though. The bar spacing on that is 1cm.
