If they can't find food, then the small animals in the neighborhood will become their targets to solve their need for food. Children will also be at risk of being bitten. They are smart, and they learn quickly. They can be dangerous, and when it comes to urban coyotes, steps should be taken to avoid encouraging them to visit your neighborhood. That means close garbage can lids tightly, do not leave pet food outside and do not leave small pets outside unaccompanied.
Coyotes love nothing better than cats and frequently take small dogs.
Inform neighbors of your sighting and encourage them to take steps to NOT attract the clever little varmints. If a wild coyote bites you, report the injury to a hospital, which will notify the state department of health. You will have to get a series of rabies shots, which are expensive and painful. Coyotes usually present little danger to livestock. While they are normally fairly solitary or roam in small groups, at times they may gang up and attack larger animals such as sheep or a pony.
