I HAD to redue my cage because my cousins broke the other one. This cage is 3 grids high the cage is on the very tippy top. It's fairly easy to clean. Also my dog can't see them so he doesn't bark at night at them. It is nice to have to pigs high because it's easier to clean and pet them. I belive I used 4 zip ties when I redid the cage. All the other zip ties were there from before because I didn't take apart the blue storage at the very bottom. Oh and my 2 guinea pigs live happily in there.
