Two out of three of my cats enjoy it thoroughly, with somewhat of a competition over who gets the top shelf. Our third cat is a 6 year old with cerebellar hypoplasia, thus the need for the ramps. She is feeling a little under the weather right now but hope she will become more interested when she's feeling better. We've put her in one of the condo's and she did seem to enjoy that for a short time. We're still hoping the 9 year old male will learn to use the scratching posts. We've tried spraying them with catnip spray but as we've only had him for the last year we don't know if we'll be able to convert him from the furniture scratching.
