Precedent with concept

Kim hyumjoo furniture designer made this stool/ dog house. 

Maria:

This is a great example of what I would like to design with my concept of interaction of human and pet. The stool incorporates a sleeping area for dogs and a place to sit, but I would like to design a space were the human and pet engages in play. In my opinion, this stool doesn't encourage play.

Going back to my definition of play and my main idea, I would like to design a playground that would make a connection with human and pet play.

Note: I am not making a product to be mass produce and be sold in stores; I am making a way of connecting human (sister) and animal (cat) play through space.
