I’m going to be moving into an apartment without AC, so being able to open windows is necessary. Issue, my kitty loves to stand up and press his paws against the window to get a better view. I’m worried that if he did that on the screen instead of the glass, it would fall out. IDK how structurally sound the window screens are.

Is there anything I could put in between the screen and the glass where air could still get through but I wouldn’t have to worry about it falling out? PS I can’t really put anything on the outside because it’s the top floor
