Actually the only ones in stock with amazon for next day delivery are the maxi dubs multy and Savic mickey 2xl (80 x 50).
If you have a pets at home near you they sell the Savic hamster plaza and ruffy cages. Can you fit a 100cm cage? If so I’d get the maxi duna multy or Savic plaza. If you can’t fit that size then the mickey 2xl is a good cage. I used it for our Syrian before upgrading him to a 100 Cm and it’s ideal for a dwarf hamster in the future. It’s a bit lower than the Alaska so not all wheels will fit but 11” ones will - depends how you set it up. Pets at home also sell the Savic sky which is basically the same cage without the narrow bar spacing- a good cage if you block off the top tubes.
Quickest option would be a trip to pets at home
But you can call first and see if they have those cages in stock. The maxi duna multy is expensive but also future proof as also good for a Syrian or dwarf hamster.
