Two different neighbors of mine just recently had a couple cats and three goats killed by coyotes.
I've been hearing them howl and yip at night for years but they always kept their distance.
Not sure what made the difference in attitude. It's not like there's been any environmental disturbances and the weather's been normal. A bit of a dry spell? I don't know
Oh, and a bear got into the garbage about a week ago. Something must be disrupting predator habitat around here.
