Sitting on Toys

Reading Bacardi's story yesterday was interesting to me. He sits on mice that he finds and lets his person dispose of them. When I bring a new toy into the house one of my cats will play with it and then when he is finished with it he will sit on it. In the past we have joked that Trevor is trying to "hatch" another toy. I bet this behavior is probably practiced by more than Buddy or Trevor. Anyone have a cat that sits on things?

One cat we adopted, Morgan, didn't like catnip, but her brother, Jackson, did. To antagonize him, she would lay on top of the catnip so he couldn't get any.
