No animal in California's recent history has generated more controversy or been the subject of more conflicting stories than this majestic, secretive animal. The mountain lion, Felis Concolor, is the largest North American member of the cat family and is the largest pure carnivore in California. Adult males may grow to almost eight feet in length and can weigh as much as 200 pounds. Adult females are usually much smaller, and normally weigh between 75 and 100 pounds. These cats are distinguished by their tawny color and very long tails.
Adults have no spots but usually have black-tipped ears and tail.
An adult male may have a home range spanning 100 square miles and an adult female 20-60 square miles with population densities averaging three lion per 100 square miles in desert areas to seven to ten lions per 100 square miles in the western Sierras and northwestern part of California. Life in the wild is not easy for the mountain lion. From a typical litter of three kittens, two will survive the first year and one will survive to breeding age. Adults may live 12 years in the wild and up to 25 years in captivity. Deer provide the lion's primary food source.
