Mesh Screen with Magnetic Closure-Keeps Bugs Out Let Breeze in, Heavy Duty - Pet and Kid Friendly, Works with Front, Sliding Doors (38 x 82 Inch)

As someone who also has kitties who insist upon visiting our (2nd story) porch and hates bugs, not sponsored but highly recommend this magnetic door screen. Easy to install and it's velcro so it's easy to peel off/roll up when not in use if your kitties try to claw it lol.
