I ordered this a few months ago for my pet rabbit but never used it since my rabbit is free roaming in my room.
It's convenient for indoor or outdoor if you want to let your pet have fun in a safe space.
You can unfold and decide the size and there is also a small door inside one of the panels.
The item is very solid metal and too heavy for an animal to move it.
I purchased it for over £25 (I can provide receipt) and never used it. It's like new!
