Ultimate Scratching Post - The Best Scratching Post. Period. Features and Benefits: Fibrous and durable sisal material naturally inspires scratching. Perfect for conditioning nails (superior to carpeting which snags nails and encourages scratching on other carpeted surfaces). Sturdy base eliminates wobbling and tipping which could discourage the cat from future attempts to use the post. The 32" post height allows the cat to stretch vertically while using the post (important for territorial marking purposes and for toning muscles). The finest materials and workmanship guarantee a scratching post that will remain attractive and useful.
