The American Pregnancy Association recommends 75 to 100 grams of protein per day for pregnant women. This requirement decreases to about 71 grams of protein daily for breastfeeding women, according to the University of Illinois McKinley Health Center.
Cougars become sexually mature at about 24 months of age. However, sexually mature cougars seldom breed until they have established a home range. Cougars have a gestation period of approximately 92 days. They will generally give birth to between one and four kittens, although two or three is typical. Kittens (also called cubs) weigh just over a pound at birth. Until they are two weeks old the kittenâs eyes and ears are closed.
Incubation periods tend to be quite a bit shorter than the time it takes for gestation of comparably-sized mammals. A chicken, for example, has an incubation period of 20 days, and even larger birds like emus have incubation periods of only around 55 days.ithin similar animals, there is some variation as well: grizzly bears have an average gestation period of 225 days, but black bears have an average of 210 days, and polar bears have an average of 240 days.
