Earlier this weeks a 126-pound Mountain Lion killed and ate a 7-pound Jack Russell Terrier near Rapid City, South Dakota. The Mountain Lion was hunted down with hounds and killed for his transgression.
Mountain Lions are slowly making their way east -- there are known Mountain Lions in Iowa, and evidence of cougar in Virginia and West Virginia has been found. Most of the lions moving east are young males, like the cougar found in South Dakota.
As far as I am concerned, a lion that kills an occasional small dog or cat in a rural area should be left alone.
The penalty for human stupidity should not be the death of a magnificent animal.
