Definition: noun; Pregnancy period in cats; the period of development of an embryo (approximately 9 week for cats); the period of time between a female cat mating and the birth of kittens.
Also Known As: pregnancy, maternity, gestation period
Common Misspellings: gestacion,
A queen's gestation period typically runs from 57 to 69 days, with the average of 63 to 64 days. I like to use "63," because it is nine weeks, equating to human pregnancy average of nine months, making it easier to remember.
