I see many people asking about which cages are good, so here are some good cage links.
UNBRANDED(If go for one with shelves and ladders, and remove all ladders and all but one shelf. If you get one with wooden perches, I'd suggest removing them as they may be made of unsafe wood. I’d suggest zip tying the small door as well.):
DCN/ALT(they often have good sales, so shop around for good prices, but stay away from the similar looking ‘prevue hendryx’ cages. They’re smaller, cheaply built, and have small doors. Ferret nation looks similar but the bar spacing is too large, so make sure to get the critter nation.):
EXOTIC NUTRITION(I would buy only cages here, not anything else. Their food and wheels are not recommended.):

- https://www.ebay.com/itm/183090691660 (This one is a fairly decent size, just a bit too small for a pair).
