Oregon State Police dispatched a cougar in the Browns Creek area of The Dalles over the weekend after it was repeatedly seen around residences chasing pets and showing no fear of people.  Oregon Department of Fish and Wildlife spokeswoman Michelle Dennehy says the cougar had been chasing after pets in the area for several days.  Sunday at dusk, it was seen staring at dogs through a fence, and then later in the evening at another residence a woman who stepped out on her porch noticed the cougar laying on her steps less than three feet away, and the cougar did not move or run away.  The same woman went inside her residence and watched the cougar in the yard, about 10 feet away, and the animal simply crouched in tall weeds and stared at her.  The resident contacted Oregon State Police, who came to the home and dispatched the cougar in the backyard with a high caliber rifle the same evening.  Under state wildlife policies, cougars that chase or kill pets, are repeatedly seen around residences and show no fear of people are considered human safety risks, and can be killed to protect public safety.
