We have no place for a scratching post for our 2 cats so...I thought, why not put it on the wall. Carpet stapled to the wall and trim out with chair rail. Some cat nip spray and they love it. We had the carpet remnant and the chair rail so it cost Sisal cat scratching posts tend to be more durable and last longer. So while sisal scratching posts might cost more upfront, you won’t have to replace them as often as carpet scratching posts..

Scratching posts of all shapes, sizes, and textures are available at most pet stores. If your cat likes to scratch on carpets, a carpet-covered post would be a good choice. But if your cat prefers couches and other nubby surfaces, a post covered in sisal or some other rope-like material might be your best bet. DIY scratching post - PVC, plywood, sisal rope, and carpet.

Some cats prefer vertical surfaces and some prefer horizontal surfaces. A good bet is to buy an inexpensive flat corrugated cardboard scratcher, available almost anywhere, and have it available (as well as a cat post).It is wise to give your cat or kitten an extra scratching surface, such as a corrugated cardboard floor mat or two. It is also a good idea to place a scratching post on each floor of your house or in more than one spot if your house has several rooms.The surface of the scratching post should be covered with a rough, tough material–sisal, hemp or something similarly nubby. Carpet does not satisfy most cats, and can confuse them because they will not be allowed to scratch the carpet on the floor of your home.There are horizontal scratchers for carpet-lovers, wedge shaped ramps for cats who scratch low on furniture, and upright posts for cats that like to stretch.You can do the same thing to make a scratch post or play set. Just use good quality wood (cedar, redwood, or other excotic hardwoods) exterior wood glue and mechanical fastners like dowels or long screws, high quality carpet (you can get some top of the line cut offs from most good carpet stores at very low or no cost), Make sure the carpet has been heated enough that the backing mesh is soft and can bend without that stiffness that can break the mesh. Use a good dose of heavy duty hot melt glue so there are no edges without glue. Trim and seal all cut edges.
To find out what your cat likes best to scratch on, observe her carefully. Does your cat prefer to scratch on carpets, drapes, wood, or some other surface? Does she scratch vertically, with her paws stretched out above her head, or does she prefer horizontal surfaces? Once you have figured out your cat's preferred scratching materials and orientation, you will be better equipped to buy a scratching post that suits her needs. A favorite material of choice is a corrugated cardboard. Economical cardboard posts are easy to replace and appeal to many cats. They usually lie flat on the floor and may come with a toy attached. Cardboard posts should be large enough for the cat to stand on them and scratch at the same time.Some owners get creative and build their own scratching posts and kitty activity centers. You can cover pieces of wood with carpet, fabric, sisal, or other materials, then nail them together to create a "cat tree" with climbing perches. This will help keep your cat entertained and satisfy her need to scratch. Any scratching post you buy or build should be sturdy enough so that it does not topple over when your cat uses it, and should be at least as tall as your cat standing on her hind legs with her front legs outstretched.
