I recently purchased a huge double macaw cage second hand which is now named Cagezilla. It was such a good deal that I figured I would see how it worked out for my possums. It has a removable partition in the middle which allows me to socialize the possums for mating or to keep them separate and safe while still having the other nearby within view and smell. It took me many hours of spray washing, scrubbing, sanitizing, cleaning, scrubbing, spray washing to get the thing clean. Someone had kept large birds in it and never cleaned it, AND THEN they kept monkeys in it. Filthy doesnt describe the mess that came off of this thing. And to boot, I found a dead and dessicated mouse in it as well. No kidding.
In the photos you can see a size comparison between Cagezilla and the Exel cage that I have the sugars in. Cagezilla is the size of about five Exel tower cages.
The possums now have a LOT more room to move around and I need to find some large branches and such to fill it out with for climbing. The only thing I would change now is that the 1" bar spacing is just too big. They cant escape, but you can easily see that it is harder for them to move around on the floor grate. So some busy climbing limbs will be very welcome.
