Our 7.5'x 300' Cat Fencing is made from a durable polypropylene mesh material that will gently sway to deter the cat from climbing on the fence. Our 7.5' tall outdoor cat enclosure has been engineered specifically to contain your pet cats in the backyard. As an additional safeguard, the top of the cat fence has a sturdy, inward-facing extender. To prevent chewing damage, the bottom two feet of our cat fence is made from our galvanized steel fence to stop the cat from crawling underneath the fence. Also, the cat fence is secured with galvanized steel ground stakes to hold down the cat fence. Deerbusters outdoor catio is high quality and can be removed and reinstalled, if necessary.
