I think the zoozone is made by hagen M&M
But when you think about it, they're being cruel themselves
since it's designed to be a guinea pig or rabbit cage, keeping a rabbit in a zoozone 1 is the same as keeping a hamster in a criceti 11.
So just because people choose to give hamsters a decent space by giving them one, doesn't mean Hagen are good, because they still market that these cages are basically 'starter' homes for rabbits etc by having the intergrated hay rack and food bowls.
