 It's just not right to leave mountain lions sitting in a trap for days on end until they die of dehydration and exposure. Much of the Texas land that is prime territory for mountain lions is privately owned. Creating even basic regulations required the support of people like Brant Buchanan. He manages a sprawling ranch in West Texas. Buchanan got involved after getting a question about a trapper in the area. This guy says he's killing 70 lions a year in these traps. Is that a problem?
