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

Named for their stubby tails, bobcats are so elusive that most people would be lucky to catch a glimpse of one in their lifetime. The bobcat is 10 times smaller than a cougar but two times larger than a housecat, and often confused with both. Because of their smaller size, solitary nature and...

It seemed like a good idea at the time: Buy a house with a two-acre property, let our energetic herding dog have the run of the place and spend blissful summer days digging side by side in the dirt with her.
