Mountain lion/ Cougar (Felus Concolor

This game species is found at all elevations. Human encroachment is probably the biggest threat to these secretive animals. Deer are the preferred prey of the lion, and may make up 75% of their winter diet. Dens are generally in rock shelters or caves. Although breeding occurs throughout the year, most young (1-6 per litter) are born from April-September after a 82-96 day gestation period. The young will be weaned at 6 weeks of age, but will remain with their mother for up to 2 years.
