Our community in central Texas has a coyote problem. I've caught several on my trail cameras in the backyard. Really have to watch out for our small pets. Someone on our community site suggested this sign as educational and for safety issues.
My neighborhood uses Nextdoor to warn of coyote sighting locations. Some have seen small pets of others killed when out for early morning walks. Not a pleasant experience. Fortunately this is a recent problem in my area and my old cats have already passed. I want my next cat to be an indoor pet but that is hard to do if you adopt a stray or a cat that is used to being outside.
