A cat's pregnancy, also known as the gestation period, typically lasts about two months, averaging between 63 to 65 days. However, it can range from 60 to 70 days, and in some cases, extend up to 72 days. This period is generally divided into three trimesters of roughly 20 days each. Early signs of pregnancy may not be visible until about two to three weeks in, with noticeable changes such as pinker nipples and a growing belly appearing later in the pregnancy. Cats usually deliver their kittens within six hours once labor begins
