~Cougar fatally attacks horse near a kids camp~SPOKANE COUNTY, Wash. -
STEVENS COUNTY, Wash - The Washington Department Of Fish and Wildlife is actively hunting a cougar near Deer Lake in Stevens County. Tuesday night fish and wildlife officials say a cougar came down from the hills and attacked a 14-year-old horse. The horse was later put down because of its severe injuries. The mare, named Diamond, was a prize horse to Sandy Ridler, who said, "even though I am heartbroken about my horse, I am glad it was not one of the children." The attack happened less than a mile down the road from Camp Gifford,a kids camp that is a summer gathering for about 150 kids.KHQ spoke with camp leaders who say the cougar was sighted in the woods just hours before the attack. The kids were moved from a wilderness camp to the main camp on Deer Lake. Chris Adams with the camp says "it would normally be about one or two people walking around the camp," for head checks. But with the attack "it's now three or four making a lot of noise because you don't want to startle anything. Also as much as possible staying indoors after the sun goes down."The Washington Department of Fish and Wildlife says the attack was rare event. Officials say they are tracking the cougar and if they catch it they will euthanize it.
 
The internet is filled with tales of cougar attacks on horses. Also, I read a great deal of literature about the 'old west' and I know that cougars are notorious horse killers. Reply
