Simple screen net cat door

I got 2 cats with their own schedule, and being their doorman is not on my priorities.

I designed this simple cat door to allow my cats to enter and leave the house freely. Without the need to leave an open door or window.

"The main problem with doors is the strict requirement for a hole in the wall"

Cutting a hole in your door is not an easy task and definitely not a simple decision.

My main issue regarding leaving open windows are mosquitoes. Or more specifically the ladies.

This is how I came to the simple solution to mount a 3D printed Cat door on both sides of a mosquito net.

All you need to do is:

1. 3D print the door parts.
2. Attach them to a screen net and fasten with screws.
3. Cut the net between the two door frames.
4. Convince your cat to give it a try.
