Revive your cat tree, or your scratching posts with the KCT Replacement Sisal Cat Posts. Over time, due to use, sisal posts stop losing their effectiveness, so replacing them with fresh ones is key. Cats naturally love scratching and stretching their claws, so giving them a scratching post will keep them entertained throughout the day and more importantly, away from your furniture. Made from a natural, durable sisal, these scratcher poles aid claw maintenance and encourages exercise. When cats scratch the posts, they shed the outer layer of their claws keeping them sharp and healthy and prevents them from becoming too long or getting infected. The posts are also a way for cats to stretch which promotes muscle tone and flexibility. This is especially important for indoor cats and kittens. The heavy duty posts are designed to withstand endless scratching, and the sturdy base will help keep it stable when in use. The freestanding cat trees are lightweight and easy to move around the home and due to its compact, space saving design, it can easily fit into small spaces. Each post is 9cm thick and can be used to make bespoke cat trees, or can be used to replace existing ones. They interconnect so you can make a selection of heights to add to a creative tree design.
