What Are the Signs That My Cat Is Pregnant?

There's a chance your cat is pregnant if she was recently in heat and had access to an intact (unneutered) male cat. Physical and psychological changes in a pregnant queen will become more noticeable approximately three weeks after breeding.

Cats have a gestation period of 64 to 66 days. A gestation duration of 63 days, or nine weeks, is considered typical.


Physical Changes in a Pregnant Cat

Looks for these signs in your cat's body indicating pregnancy:

  • Heat cycles cease: This may be the first sign you notice of a cat's pregnancy. If a cat has been going through  every 10 days to two weeks, and suddenly stops, it is likely she is pregnant.
  • Nipples swell and become rosier in color: Breeders call this "pinking-up," and it may be the first visual sign you will see in a pregnant cat.
  • Change in appetite: A pregnant cat may have a decrease in appetite early in her pregnancy. In the second half of pregnancy, she will show an increased interest in food. After all, a pregnant cat is not only eating for herself, but for several fetuses.
  • Weight gain: Most pregnant queens will gain about 2 to 4 pounds of body weight over the course of pregnancy.
  • Vomiting: Pregnant queens may be subject to a few bouts of "morning sickness," much as human mothers-to-be. This in itself is not necessarily a reason to worry, but if the vomiting continues or is frequent, contact your veterinarian for help.
  • Enlarged abdomen: Sometime around the fifth week of pregnancy, a pregnant cat's abdomen will start to swell noticeably. It will continue to enlarge until time for birthing.

Personality Changes in a Pregnant Cat

These character and mood changes are also indicative of pregnancy:

  • Affection increases: Your cat may become more affectionate than normal and frequently seek out your attention. By all means, give it to her!
  • Increase in sleeping: Many pregnant queens will sleep for more hours in a day than before pregnancy.

Clinical Diagnosis of Pregnancy in Cats

It may not be essential to seek a formal diagnosis from a veterinarian if your queen has had regular medical care and prior indicators of pregnancy are visible. Your veterinarian should, however, inspect your cat to ensure she is in excellent health.

  • Palpation of the Cat's Abdomen: Your veterinarian may be able to feel your pregnant cat's fetuses by palpating and gently pressing on her abdomen. This typically happens around the 17th to 25th day of pregnancy.
  • Ultrasound of Your Cat's Abdomen: An ultrasound may detect fetuses as early as the second week of pregnancy, and heartbeats may be detected sometime after the third week.
  • Radiographs (X-rays): Your vet can take a radiograph of your cat's abdomen when she is further along in her pregnancy to determine the number of kittens she is carrying. This is a minor amount of radiation that will not be harmful to the kittens or the mother. Kitten spines and skulls begin to be visible on x-rays after about 42 days into the pregnancy.

If your resident or rescued cat is truly pregnant, you'll have to make some tough choices. If you decide to spay her to end the pregnancy before it reaches term, you should do so as soon as possible. If not, be prepared to assist in the care and placement of the kittens.

Signs Your Cat Will Give Birth Soon

When your cat is in active labor, try not to disturb her. Keep an eye on her from a safe distance to ensure she does not become distressed. These indicators signal the arrival of kittens:

  • Nesting Activities: As the birth gets closer, your pregnant cat may seek out quiet, private places for the birth to take place. This typically begins up to two days prior to labor, but it may only begin a few hours prior.
  • Restlessness: About 24 to 48 hours before labor, the pregnant queen may seem restless or anxious. She may go in and out of her nesting area, almost as if pacing.
  • Vocalization: In addition to the pacing and restless behavior, the pregnant queen may meow and cry out more than usual.
  • Lowered Body Temperature: Within 12 to 36 hours of labor, your cat's body temperature will drop below 100 degrees Fahrenheit (normal temperature is usually between 100.5 and 102.5 degrees Fahrenheit).
  • Loss of Appetite: Your pregnant queen will likely have had an active appetite during her pregnancy. As she comes close to labor, she will have a drastic decrease in appetite. 
  • Vulva Licking: As labor fast approaches, your cat will begin licking her vulva to clean a mild discharge. You will likely not see this discharge, as she will want to keep the area clean.
If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
