Query: Our Cats Do Not Like This Product

We purchased this item on a lightening deal before Christmas and paid about $40. I'm glad we didn't pay any more than that. Our cats have several scratching posts around the house and the bases are all covered with carpet. On this new "Smart Cat" Scratching Post, the base is hard plastic, slick and slippery. The cats can't get a foot hold with their back paws or claws when they stand up on it to scratch. They have tried standing off of the slick base to scratch the post with their front claws, but it's awkward for them. They've also tried laying on top of the base to scratch the post with their front paws, but they slide around on the hard plastic surface. As a result, they now just ignore this item. We are going to try and cover the base with carpet ourselves. If this doesn't work, we may end up donating it to a local shelter.
