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.
As has already been mentioned, the pregnancy will last about 35 days, although some will give birth in as few as 30 days and others have been known go as long as 46. Most, however, will have a normal 34 - 36 day pregnancy. If the female does not give birth by her last expected due date, give her at least another 11 days before assuming that the breeding wasn't successful. Your expectant mother will require a nest box at least one week before her first due date.
