Cats need a place to scratch, which usually means a scratching post or your furniture. While you can buy a scratching post, you might want to make one for your cat instead.
By making a scratching post, you can customize it just for your cat. That way it can be the perfect height with the right material that your cat enjoys scratching. At least if you make your own scratching post, you won’t have to worry about your cat being more fascinated with the box that the scratching post came in.
