Thanks...We lived in a rural area of Oregon for a number of years and never had a problem with them though they were there. Hunters hunted them legally with dogs and the cougars knew that man would kill them.
Right after moving north they outlawed hunting cougars with dogs and they lost their fear of man to a degree and then became a problem with pets and farm animals.
