Short (14 inches)

These “short” kits for converting existing wooden walls and fences into cat-proof fences have relatively short (14-inch) extender arms. Get an “economy” kit if you need relatively few extender arms or a “standard” kit if you need more extender arms. To convert vinyl, chain link, or decorative metal fences into cat fences, use one of these kits combined with u-bolts (2 per extender arm) suited to your posts.
