Cats can push Milguard window screens out. Locks or latches available?
So at 2 a.m. my wife discovers one of our indoor cats is missing and a Milguard double-hung window screen is ajar. Is there a way to secure the screens that doesn't void the warranty? Wedges? Thin hook? These are the screens with the pull tabs at the bottom to compress the top springs. The lower channel is not deep enough to keep a fat cat from pushing it out!
