For store-bought cages, I've been using the ZooZone 2 for my dwarfs for over a decade. It is apparently rather hard to get hold of now, though. The
Ferplast Maxi Duna Multi is very similar in style to it, and may be preferable as it has smaller bars on top.
Should I replace the ZZ2, I was considering getting the
Bucatstate Metal Hamster cage, which is a bit larger (and cheaper) than the
Nightangel cage of a similar design.
And although you're asking about cages for dwarfs, I'll just add in that, for Syrians, one of the the best store-bought cages is possibly the
Savic Plaza XL, which is what I'm hoping to get one day.
