How they develop: Cougars begin breeding at about 3 years of age. Typical litters have 1 to 6 kittens born after a 3-month pregnancy (people have a 9-month pregnancy). Their eyes open in 8 or 9 days and the young are weaned from the mother in 2 to 3 months. The kittens may remain with the mother into their second year.
Ok I read the study but it is for you smarter types to really understand. I did pull out the basic numbers though.https://research.wsulibs.wsu.edu:8443/dspace/bitstream/2376/1033/1/v76%20p15%20Keister%20Jr.%20and%20Van%20Dyke.PDF Estimated population 1900-2100 (kittens excluded) Female/Male ratio 50/50. Could be higher males in Washington do to more females being harvested. But with only ~200 cats being harvested and an estimate of 60% of those being female the difference would only be ~20 less females than males from the year before. http://wdfw.wa.gov/wlm/game/management/2009-2015/final_game_management_plan_2009-2015.pdf Page 85So out of 950-1050 females 75% would breeding age. 712.5-787.5 females with an annual pregnancy rate of 63%. 448.9-496.1 females will have an average of 2.4 kittens. That is 1077-1191 new kittens. Adjusted for mortality of 31% (this includes the kittens dieing due to the mother dieing) would be 743-822 new kittens in a year.
