Colorado’s mountain lions, bobcats and lynx are under threat from trophy hunting and need protection now.

The mountain lion known as P-47 survived fires, freeways and hostile ranchers. But in March, the 3-year-old big cat—tracked by California biologists since his kitten days—succumbed to a hidden hazard: an insidious form of food poisoning.

As the year comes to an end, animal advocates celebrate the passage of three new animal protection ordinances and resolutions in Montclair.

Coyotes go out of their way to stay out of ours: They’re partial to open areas but seek hiding places in cities.
