When is it noticeable that a cat is pregnant? - in detail
Detecting pregnancy in a cat becomes more apparent as the gestation period progresses. Initially, during the first two to three weeks, subtle changes may occur but are often difficult to notice. The cat’s behavior might shift slightly, such as increased affection or mild lethargy, but these signs are not definitive. Around the third week, physical changes begin to emerge. The cat’s nipples may become more prominent and take on a pinkish hue, a phenomenon known as "pinking up." This is one of the earliest visible indicators of pregnancy. By the fourth week, a veterinarian can often confirm pregnancy through palpation or ultrasound, as the embryos start to develop and become detectable.
Between the fifth and sixth weeks, the cat’s abdomen will visibly enlarge as the fetuses grow. This is when pregnancy becomes more obvious to the naked eye. The cat may also exhibit changes in appetite, often eating more to support the developing kittens. Behavioral shifts, such as nesting behavior or seeking secluded spots, may also become more pronounced as the cat prepares for birth. By the seventh week, the movement of the kittens can sometimes be felt by gently placing a hand on the cat’s abdomen. In the final weeks, the cat’s body will further expand, and mammary glands may enlarge as they prepare for lactation. Monitoring these physical and behavioral changes can help determine the progression of a cat’s pregnancy and ensure proper care is provided.
