Cougars inhabit and develop on land, outside of bodies of water, and the young are born live on land, not hatching from eggs or roe. The species reproduces through homogamy, always with fertilization and without generational change. Cougars mate at any time of year, and the female carries the offspring for about three months before giving birth to a litter of 1–6. The mother raises the kittens alone, and the size of a litter is 1–6. The interval between reproduction is from 1 year to 2 years and 6 months. Sexual maturity occurs from 2 to 4 years.
