These cages are great! My piggies run, hop, climb, and "yell" at me all the time. I have used store bought cages in the past when I didn't know better and I must say, I feel so bad for those piggies. It isn't living being kept in a space they can barely move in. In this cage they have room for multiple houses, tunnels, and other toys while still having room to just run and popcorn. They can be a little tricky to put together at first but once you get the hang of it, it's really not so bad. I have stands for my cages too, which are great for storing all my piggy supplies. I would recommend these cages to anyone wanting to keep piggies for pets.
