Female kittens usually enter their first heat cycle around the age of six to eight months. This is the time when they become sexually mature and can reproduce. It is important to spay female cats before their first heat cycle to avoid unwanted pregnancies.
Cats have their first estrous (reproductive) cycle when they reach puberty. On average, puberty, or sexual maturity, first occurs in cats at about six months of age, but this can vary slightly by the time of year (length of daylight hours).
