Boo loves to play with toys while sitting on a Scratch And Roll. I had a long handled grabber that I had brought into the house from the garage to use during a live stream and Boo thought it was incredibly interesting, in fact, he was captivated by it.
I found this grabber at a local dollar store where it cost only a dollar. If you think your cat might like one, they are also available on Amazon. They cost a bit more there. Here is the link: https://amzn.to/2POQ5fw
