Windproof Catflap

The windproof catflap is shaped like a figure of 8 on its side. It is pivoted in the middle. It can rotate just under 180 degrees.

Whichever side the cat is on, the cat pushes on the left flap to get in.

There is a slight size difference between the 2 halves, which helps with wind resistance. The inside left half is slightly bigger.
