Make yourself appear larger by picking up your children, leashing pets in, and standing close to other adults. Open your jacket. Raise your arms. Wave your raised arms slowly.
Yell, shout, bang your walking stick against a tree. Make any loud sound that cannot be confused by the lion as the sound of prey. Speak slowly, firmly and loudly to disrupt and discourage predatory behavior.
Maintain eye contact. Never run past or from a mountain lion. Never bend over or crouch down. Aggressively wave your raised arms, throw stones or branches, all without turning away.
Assess the situation. Consider whether you may be between the lion and its kittens, or between the lion and its prey or cache. Back slowly to a spot that gives the mountain lion a path to get away, never turning away from the animal. Give a mountain lions the time and ability to move away.
If attacked, fight back. Protect your neck and throat. People have utilized rocks, jackets, garden tools, tree branches, walking sticks, fanny packs and even bare hands to turn away cougars.
