I think you have a lot of work ahead!
Maybe she will teach them DW and DD1's cats go out on the enclosed porch through a window obviously left closed in the fall/winter/spring due to our temperatures. DD1's cat (the one on the couch arm) will paw/scratch at the glass to let us know when he wants to come back in. It is loud enough to be a repetitious knock. DW's cat just doesn't get it. She'll sit at the window using her near silent meow which is, of course, not real helpful. Eventually we do notice she is sitting there.If only all my dogs did that!
