Maybe y'all can help. I'd love to be able to open my windows and enjoy the fresh air, but I have 3 cats who will claw the screens to shreds and escape! Is there a super-strength type of screening out there? (not super-expensive, though -- I really only need enough for 3-4 windows) Or any alternative suggestions? I've roamed the aisles of Home Depot and haven't discovered anything that will still keep the bugs, etc out, and also allow the cats to lounge in the sill area. What do you other cat owners do?
