Kitten season typically occurs from early spring through late summer or early autumn. In many places, this means kittens are most commonly born between March and September or October. The season is driven by longer daylight hours, which trigger the reproductive cycle in unspayed female cats. During this time, cats can have multiple litters, leading to a significant increase in kitten births and arrivals at shelters. In the UK, kitten season is generally noted from March to September, peaking in the summer months. In the US, it often starts around April or May and can extend into the early autumn, with a peak in May or June. The season is linked to environmental cues such as daylight and temperature, which influence cats' hormonal cycles. Overall, kitten season is marked by a surge in feline births and shelter intakes from spring to fall, with most kittens born during the warmer months when conditions are favorable for raising young cats.
