In my opinion it's too small annd I heard creaky...
Before I got my chin, I looked at that exact cage and read some customer reviews on it-I didn't like what I heard. Then I did some research and found out it is considered too small by many chin people. I just recommended this website twice already in the last 10 minutes-why not go for a 3rd, lol-petchinchillas.info -it helps pick a good cage, helps make a not so great cage into a good one, and also helps people build their own. I ended up building one for my guy-I love the total control and I honestly enjoyed building it (with my dad). Then I added on a few months later and his cage is huge now for just one chin-can't wait to get another to help fill it up, lol, but he truly enjoys the space.
I'd consider getting another bigger one. If yours is in good shape, sell it on ebay, but I'd reccomend it for rats, not chins. You can, but I wouldn't.
