Do's and Don'ts in Cougar Country While recreating in cougar habitat, you should:
1. Hike in small groups and make enough noise to avoid surprising a cougar.
2. Keep your camp clean and store food and garbage in double plastic bags.
3. Keep small children close to the group, preferably in plain sight just ahead of you.
4. Do not approach dead animals, especially deer or elk; they could have been cougar prey left for a later meal.
If you encounter a cougar:
1. Stop, stand tall and don't run. Pick up small children. Don't run. A cougar's instinct is to chase.
2. Do not approach the animal, especially if it is near a kill or with kittens.
3. Try to appear larger than the cougar. Never take your eyes off the animal or turn your back. Do not crouch down or try to hide.
4. If the animal displays aggressive behavior, shout, wave your arms and throw rocks. The idea is to convince the cougar that you are not prey, but a potential danger.
5. If the cougar attacks, fight back aggressively and try to stay on your feet. Cougars have been driven away by people who have fought back.
