Update: This attack happened at the Arosa Ranch. The poor horse was chased to exhaustion and then attacked. This cougar was estimated at weighing over 180 lbs.
According to John, male cougars have a territory of 150 square miles and females have half that.

John and Marianne reported that a cougar attacked one of their horses on Saturday. The Vet went out but was not able to save the horse. 🙁
They saw the cougar and said that it was a VERY big cat!
