Mountain lions are amazing creatures that are rarely seen by humans but several communities in North Texas have reported an uptick in big cat sightings. Mountain Lions are relatively uncommon, secretive animals according to Texas Parks & Wildlife. In Texas, the Mountain Lion is found throughout the Trans-Pecos, as well as the brushlands of south Texas and portions of the Hill Country but there’s no established population of mountain lions in North Texas, making several recent sightings extremely rare.
