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.
Some veterinarians may recommend a kitten be vaccinated at the age of 9 weeks and then one or two more times for the next two or three weeks, until the cat is 13 weeks old. A booster shot of the vaccine is recommended every year by its manufacturers.
