The small and large felted wool cat caves are beautiful and the colors blend perfectly with my decor. They look like something I would have purchased at an art show. One cats loves playing with/on them, but won't actually get inside; he likes to hide things in them and then reach in after it! My other cat has zero interest. The openings are a bit small, especially on the large cat cave, so I think that has something to do with it. I'm hoping that over time, he'll brave his way inside!
