I have a small cabinet with drawers of art supplies in my dining room/solarium. I just noticed that the top drawer was slightly open by about 3 inches. I haven’t opened that drawer for a few days, and when I did, I thought I closed it, as one does, and none of the cats can reach it.

If someone was/is in the house, the dog would be letting me know; he is uber-territorial and protective, and at least one of the cats would be hiding.
