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.
Duration [edit]. For most species, the amount a fetus grows before birth determines the length of the gestation period. Smaller species normally have a shorter gestation period than larger animals. For example, a cat's gestation normally takes 58â65 days while an elephant's takes nearly 2 years (21 months).However, growth does not necessarily determine the length of gestation for all species, especially for those with a breeding season.arious other factors can come into play in determining the duration of gestation. For humans, male fetuses normally gestate several days longer than females and multiple pregnancies gestate for a shorter period. Ethnicity may also lengthen or shorten gestation.
