After how long can you tell if a cat is pregnant? - in detail
Determining if a cat is pregnant typically becomes possible within two to three weeks after conception. Early signs of pregnancy in cats are subtle and may not be immediately noticeable. Around the 15th to 18th day post-mating, a veterinarian can perform palpation to feel for small, firm masses in the abdomen, which are the developing embryos. However, this method requires expertise to avoid harming the fetuses. By the third week, physical changes such as pinkening and swelling of the nipples, known as "pinking up," may become visible. Behavioral changes, such as increased affection or appetite, can also hint at pregnancy but are not definitive.
Between the fourth and fifth weeks, an ultrasound can confirm pregnancy by detecting fetal heartbeats. This non-invasive method is safe and provides reliable results. By the sixth week, the cat’s abdomen will begin to visibly enlarge as the fetuses grow. At this stage, an experienced veterinarian may also use X-rays to count the number of kittens, though this is usually done closer to the end of the pregnancy to avoid unnecessary radiation exposure.
By the seventh week, the cat’s pregnancy becomes more apparent as she gains weight and her abdomen becomes rounder. Behavioral changes, such as nesting behavior, may also intensify as she prepares for birth. While physical and behavioral signs can provide clues, veterinary confirmation through palpation, ultrasound, or X-rays is the most accurate way to determine pregnancy. Early detection ensures proper care and preparation for the arrival of the kittens.
