Recently acquired a SuperPet, and thought I did quite well, considering it was my only choice in the store....LOL Got it set up and thought it was SO COOL. Posted about it on Acme, and got some nice suggestions on modifying it. Yes, the side doors are small, but my old cage had ONE door and was 2 feet deep, so even small doors are nice. It was also pointed out that the tubes connecting each level could be hard on a fert's back, so I watched very carefully (cage is right next to my computer, so observation was easy), and yes, I could see they had to sort of struggle up the slippery interior. I got some extra ramps and shelves, and it is now 8 leveled (couple corner shelves)...but the ramps still looked slippery to me, so I hot-glued carpeting on them. My 4 girls rip up and down them like crazy, so I guess they like the modifications. Last thing I will add is maybe a couple small open-weave plastic baskets with blankies in them. The tubing is on the floor and they play in that when they're out. I must be really lucky, because I only need 1 litter box on the bottom. I've seen all 4, lounging around at the top, then suddenly make a dash to the bottom for the litter pan. And, yes, I thought the wheels looked pretty flimsy, so I didn't use the stand. I'll set their old cage on it, and connect the 2 (haven't figured out how yet, but somehow through one of the small side doors. All in all, a nice cage......with mods. Diane I.
