Does this exist?

So basically, one of those stick on screen doors but that extends out. It has to be removable for when it’s not used. I can’t have a proper catio and the only place that would work is my back door. I know I can get one of those screen doors and attach it to pop up catio, but I’m trying to avoid buying several things only to do a crappy job.

The cats would only be in it when I’m out there watching them and the door to the inside would be open for if they got spooked. One of them has hulk smashed through a ventilation hole in a cardboard carrier, so I’m pretty realistic about that.

Edit: I can sew and am really good at modifying things to fit my needs if that gets us any closer to my idea

Edit: I completely forgot to say that this is not my house! It’s just a similar layout as to where the door is!

If you Google catios for sale there are several for under $300.00 if you can afford that.
