In a Wildlife magazine (Jan. 2017) I saw an article that studied urban & suburban coyotes verses open range regarding their impact on the environments.
I found it interesting that the study found that humans, domestic animals and urban coyotes can coexist. They used to be and in some places are still considered nuisance animals.
They study remarked that urban Coyotes usually don't eat garbage, domestic dogs or domestic cats they have found. Coyotes prefer to eat opossums, raccoons and the like. It helps to keep the songbird population intact as these animals can't feed on the birds anymore.
Also it seems that where there are Coyotes there are no free range cats sighted. I have to assume they mean wild cats?
My Mom would like Coyotes in her area then as she has a resident Bobcat and is in fear that her little dog might be eaten so she always has to watch her when she is outside in the fenced backyard. Kinda defeats the purpose of the fenced backyard.
Here are come clips from the article, especially those that live in California might be interested:
