Currently Oregon has about 6000 cougars. Wildlife expert says they'd like to have about 3500. Managing this growing population is difficult and Steven George with the Department of Fish and Wildlife says people who feed deer in their neighborhoods aren't helping: “Cougars primarily eat deer it’s their main food source. And you see a lot of people feeding deer over time especially around subdivisions and it’s increasing the deer populations in the subdivisions and that's creating a real food source for cougars.” State lawmakers are considering a bill that would again allow dogs to be used in hunting cougars. Wildlife experts trapped and killed a cougar in the Deschutes River Woods area last week.
