"My cats do not really like to share toys, but they love to share this one. If one of them is lazily pushing the ball around, the other one will watch intently and wait for their chance to push it. Sometimes I will push the ball around and they will sit with me and play. They really like it when I push it really fast and it stops and they try to get it out.
They get bored of it easily, but once they remember they have it, they enjoy it."
