One of the commercial cat hammocks I had in the catio broke (it really wasn’t designed for outdoor use and degraded in the sunlight). I had what I thought was a brilliant idea to make a triangular hammock to fit a corner.

The old hammock was square and needed support for all four corners. A triangular hammock would only need three supports. I used a large washer and screw to attach the hammock to the wood, and originally had it flat. Here is where the physics part comes in. The fabric sags when weight is applied. The hypotenuse of the triangle sagged too much and made a slide rather than a hammock when the corners were all at the same height. It took some experimentation to get the corners at the right heights so a pouch formed to hold a cat comfortably. My cat was remarkably patient with me putting her in and out of the hammock.

In the end, the right angle corner needed to be much lower than the hypotenuse corners to keep the cat from falling out. We got there, but it wasn’t pretty.
