About 10 to 20 minutes. When a cat gives birth, the average time for each litter is half an hour to an hour, and the interval between each litter is about 10 to 20 minutes. For cats, they usually can give birth to four to six kittens in a litter, which means that under normal circumstances, it takes up to four to six hours for a cat to give birth. Some cats are likely to have dystocia during delivery because their fetuses are of different sizes and positions.

Cat birth precautions:

1. Hair cutting is very necessary, but not all hair needs to be cut short, mainly around the nipples and birth canal. Cutting the hair near the cat's nipples and birth canal is mainly to help the kitten nurse, and to prevent the hair from getting too long and getting entangled with the umbilical cord during the birth process.

2. Arrange the delivery room. Arrange the location of the delivery room in a warm and quiet place. It is best to use plastic or cardboard as the material of the delivery room. These two materials have poor heat dissipation and can maintain the temperature of the delivery room well.

3. Take nutritional supplements. Giving birth to a cat is really taxing on the body, and you have to feed the kittens afterwards. You can buy some chicken, fish and other foods to make soup to supplement your cat’s nutrition.

4. Observe the cat’s mental condition. If you find that the cat is not in good spirits or even has a fever, you need to send it to the hospital to check whether it is infected or if there are still kittens in the belly.
