Quick Answer. It takes up to seven hours for a cat to give birth to a litter of kittens. Once active labor begins, the first kitten normally arrives within an hour, with about 15 minutes between the birth of each kitten. As each kitten is born, the mother cat stimulates it to breathe by licking it with her rough tongue.
