Cats usually give birth to babies in about two months of pregnancy. Counting from the first day of successful mating of kittens, the period of pregnancy is approximately 62 to 67 days, with an average of 65 days. If the baby is born earlier than 58 days, the kitten is likely to die prematurely or be weak during delivery, which is considered premature birth. Kittens born after 71 days may be larger than normal and may die in infancy. Therefore, if the cat has not given birth in about 70 days, it is best to take it to a pet hospital to consult a professional pet doctor.

Signs that a cat is pregnant and about to give birth to a baby:

1. Appearing anxious and uneasy, squatting on the ground, or lying in the cat's bed and making sounds, which may It’s caused by the female cat’s anxiety about giving birth.

2. The amount of water consumed will also increase, the frequency of urination will increase, and the food intake will decrease. Urination becomes frequent as the uterus presses on the bladder.

3. The body temperature drops by about one degree and will return to normal body temperature during delivery. Cats' normal body temperatures are higher than ours. Usually between 37.7–39.1°C. One or two days before birth, the body temperature of pregnant cats will drop a bit, usually to below 37.7°C.

4. When preparing to give birth, fluid will flow out of the genitals.

5. Red nipples can squeeze out milk and the cat’s abdomen begins to shrink. Usually begins 24–48 hours before kittens are born. You can see some thick beige discharge from its nipples. This is colostrum.
