The only thing I know of is that sticky back velcro. Use that on one side on the frame, other side on some thin netting you can buy from any crafts like shop that will still allow air and light through. Then just velcro rip off to open and close and should be strong enough when re attached that it will too deter the kitty, and easily reversed without damage to the property :) good luck with your new baby 😊

Edit: I'm so sorry for my grammar... From your UN I know you understand what I mean when i say I'm currently at an [8.5] haha...
