Mountain lions, also called cougars or pumas, once lived across most of North America. Today, they are mainly concentrated in western states, though sightings are increasing in unexpected places. Experts say habitat expansion, growing deer populations, and reduced hunting pressure are helping some populations rebound.
California: America’s Mountain Lion Hotspot

California is home to one of the largest mountain lion populations in the country. These predators roam forests, coastal ranges, foothills, and even areas close to major cities like Los Angeles. Encounters remain rare, but sightings near hiking trails and suburban neighborhoods have become increasingly common.
Colorado: Prime Cougar Territory

Colorado has rugged mountains, dense forests, and abundant deer populations, perfect conditions for mountain lions. Wildlife officials estimate thousands live throughout the state, especially in rocky terrain and foothill regions where prey is plentiful.
Florida: Home of the Rare Florida Panther

Florida hosts the endangered Florida panther, a subspecies of mountain lion found mainly in the southern part of the state. Although their numbers remain low, conservation programs have helped the population slowly recover over recent decades.
Oregon: A Growing Cougar Population

Oregon has seen a steady rise in mountain lion numbers. The animals thrive in the state’s forests and remote wilderness areas, though occasional sightings near towns and hiking trails have raised public awareness about living alongside large predators.
Arizona: Desert Predator Territory

Arizona supports mountain lions across much of its rugged desert and canyon landscapes. These elusive cats often stay hidden in rocky terrain, but hikers and ranchers occasionally report encounters in remote regions.
Washington: Cougars in the Forests

Washington is believed to have thousands of cougars living in forested and mountainous regions. Wildlife experts say the animals are widespread throughout the state, especially in areas with healthy deer populations.
Texas: Sightings Across Hundreds of Counties

Texas continues to report mountain lion sightings in many regions, especially western parts of the state. While exact population numbers remain unclear, sightings have been documented across hundreds of counties.
Why Encounters May Be Increasing

Scientists believe mountain lion sightings are becoming more common partly because humans are expanding into wildlife habitat. At the same time, young male cougars are known to travel huge distances searching for territory, leading to surprise sightings far outside traditional mountain lion ranges.
What To Do If You See One

Wildlife officials recommend staying calm if you encounter a mountain lion. Never run, because fleeing can trigger a chase response. Instead, stand tall, make yourself appear larger, maintain eye contact, and slowly back away while giving the animal space to escape.
