I can't let the cats have free run of the house at night anymore because you can't see them in the dark, which is a real problem for the elder folk who can barely get around as it is. But if I close my door, then I'm worried that I won't be able to hear if they need help. So I'm trying to figure out a way to keep my door cracked open enough that I can easily hear what's going on in the rest of the house, but not enough that a cat could get out and wreak havoc.
Any ideas?
