We bought the crazy pants, too! See them lying on the floor in the back? The kitties were a lot more interested in the cardboard condo hubby was making for them. I could have sworn that I had a photo of hubby trying on the crazy pants but I can't find it. Maybe he made me delete it.I bet those CRAZY pants would be a hit with kittens though. They would love to scamper through the waist and come out through the legs. Did you get the chance to try them out with kittens rather than adult cats??
We had a cat tree that had seen much better days so we bought our cats a new, taller, bigger, and better one. Hauled it home, got it set up and...nada. We sprinkled catnip on it, tried catnip spray. Nope. They just absolutely were not interested in it. So a friend of ours who had just got a cat ended up with a brand-new cat tree and our cats happily went back to their old ratty one.
