You can tell a cat is about to give birth by observing several behavioral and physical signs that typically occur in the 24 to 48 hours before labor begins:
- Nesting behavior: The cat will seek out a quiet, secluded, and comfortable spot to give birth, often scratching or rearranging bedding to prepare a nest
- Loss of appetite: Most cats stop eating the day before labor starts and may refuse even their favorite treats
- Restlessness and increased vocalization: The cat may pace, appear anxious, groom excessively (especially around the vulva), and vocalize more than usual
- Physical changes: The mammary glands enlarge and may start producing milk a day or two before birth; nipples become larger and pinker
. The cat may lick her belly and vulva frequently
- Temperature drop: A noticeable drop in body temperature (below about 100°F or 37.5°C) usually occurs within 24 hours before labor
- Visible contractions and straining: Early labor may include subtle contractions not easily seen, progressing to visible abdominal contractions and straining as kittens begin to pass through the birth canal
- Vaginal discharge: A small amount of clear to bloody mucus may be present just before or during labor
These signs collectively indicate that labor is imminent. The entire labor process usually lasts from 6 to 24 hours, with kittens typically born every 30 to 60 minutes once active labor begins
. Monitoring your cat during this time is important, but unless complications arise, minimal interference is advised
. If your cat shows strong contractions for more than 20 minutes without delivering a kitten, or if labor lasts more than 2 hours without progress, contact a veterinarian immediately
