Extra Tall Cat Scratching Post

For long, slender cats, a regular sized scratching may not seem appealing. They may want to use your expensive sofa instead. Extra tall scratching posts are made to let your cat stretch those long limbs as they scratch. Of course, cats are picky creatures, and they may not like to use any size post at all. The best you can do is give them the option.
