sounds to me like its just surviving ?
the more folks move into the woods, the less woods there are for critters, forcing more and more into contact with humans
plus easier meals at times in rural yards,
many studies have been done on Coyotes, and many show they have a huge diet of Cats??
domestic cats
so, more than likely there are a lot of coyotes in local neighborhoods all the time
just many folks don't see them

unless its sick or injured, a healthy Coyote I doubt has any interest in attacking a human!
people tend to think the worse cause they rear?? or ???
odds are very low it wall harm anyone
now PETS
if there small enough , I can see them becoming a possible food source!
as again, its just looking to survive and there opportunistic, they will eat whats easy to get!
