A female cat can get pregnant when sheâs as young as 4 months old, unless sheâs been spayed to prevent that. Queens can keep going into heat every 2 to 3 weeks from the spring through the early fall, making them ready to reproduce more often than not. A catâs pregnancy lasts about 63-65 days.
The domestic cat usually reaches puberty at around nine or ten months of age. A sexually mature female cat goes into heat, or estrus, several times a year; during estrus, she is both receptive to, and attractive to, male cats. The gestation period of the cat is about 65 days; the average litter consists of 4 kittens. Kittens are born blind, deaf, and helpless. Their eyes open at 8 to 10 days of age, and they begin to be weaned about 6 weeks after birth.
