I sure wish up you well, susie!! I don't have the answer, but wish I did. We have coyotes here as well, but they seem to have a pretty wide range that they travel. I'll hear them one night, and then nothing for days. I keep Bella and Lucky inside here at the cabin, but at the house, some of our cats stay out at night, and some stay inside. So far we have not lost any to the coyotes or in the daytime to the hawks. Or for that matter, at night we also have large owls, which I think would be capable of taking at least one of the smaller cats. There are also foxes, although I don't know if they prey on cats or not.
I hope for the best for drifter and cuddles.
Best Regards, Les
