DougGuy,
Sorry for your loss. Whether we have them for a week or 10+ yrs, they grab your heart and stay.
I live in a small SoCal city, we have coyotes. My Daughters cat is allowed out between 0800-1700hrs. I've found their fresh scat some mornings in my backyard. Completely fenced/walled. We also have opossums and raccoons. I've disposed of one yote.
