This is so very sad. We live on an acre in the edge of Carson City, NV. All desert, and you can hear the coyotes howling at night....it is the cats that go missing here so much. We are fenched in and have no doggie dog. I spend a lot of time opening and closing the doors!!! So very sorry for your Aunt's loss, so very sad. Give her hug for me, ok?? Sandy S
