Colorado voters will decide via Proposition 127 on the state ballot whether the decades-old hunting of mountain lions and bobcat trapping should continue — or be banned outright. The measure has stirred fervent support among animal welfare advocates and fierce denouncement by major hunting organizations. Colorado Parks and Wildlife, which regulates hunting in the state, has not taken a stand on the question, and agency leaders have promised to fulfill the will of the voters. Regulated hunting of mountain lions began in Colorado in 1965 in response to decades of unregulated hunting and poisoning that drastically reduced the big cat population. Proposition 127 was petitioned onto the ballot by a coalition called Cats Aren’t Trophies.
