Cat Escape Prevention Fence Can be assembled without tools. Although there are no instructions, you can see how to assemble it on the manufacturer's official YouTube channel. I've had it set up for about 2 years, but I don't seem to need it anymore, so I'm putting it up for sale here. The cat I have is healthy and has no illnesses ₍˄·͈༝·͈˄₎◞ ̑̑ Please understand that this is a used item before purchasing. I've already packed it up, so the photos are from the internet.
