Great

This is really strong and my chinnys love it. My chinnys are young and quiet destructive at the moment so things in their cage needs to be strong and they are able to hang off this and it not come loose.

Another mixed review

From human's point of view I had difficulty opening and attaching these to cages, but I do have arthritis in both hands so I think it is only a problem for people with similar health issues. Oldest and youngest Chinchilla very happy with this and gnawing away as I type :-) Middle lady sniffed, licked and has since totally ignored. You win some, you lose some.

Bought this as it is chinchilla safe as its made from pumice. Fixes easily to the cage and my girl loves it! It provides her endless amounts of fun and it brilliant for gnawing!
