We broke down and purchased a well engineered cat door for the window to the catio. It keeps out the weather and more importantly, flies.
The cats are used to going in and out at the right side of the window. The first solution was cutting a flap in the screen of the window. In winter, that was very cold. The next solution was to replace the screen with flexible vinyl, with a flap cut in. With a heavy curtain in front of the window, it was better than the screen, but the window still needed to be closed during a rain storm.
The door insert fits right into the window channels and reduces the air leak to almost nothing. We could even take away the curtain and get more light. The cats were not impressed. We tried just poking them out the window, but the magnetic click at the bottom scares Thor, the gray tabby, my 17 pound baby. We tried holding the flap open, but that lets in the flies. We decided to just let the cats figure it out.
Izzy the calico was the first to figure it out.
Thor has still not braved making the window click. He will sit on the windowsill looking mournfully out, but won’t let me near him (poking him out the window was traumatic, the door lock clattered in a scary way). It has been a week and he still won’t go out. On the plus side, we see more of him when he doesn’t spend his whole day outside eating bugs and frogs. He might loose some weight without all the extra wriggly snacks too.
