At this point I stopped to test how the tetrahedron would look on my cat. My hope had been that the stiffness of the edges would be enough to make the soft tetrahedron stand on its own once it had a cat inside. However as he started walking around it became apparent that a frame was required for it to maintain its shape, especially when you consider how the tail deforms the soft sides. I had thought that the tail could go under the bottom border, but my cat had other ideas.
