Why does a cat shed a lot in autumn? - briefly
Cats shed excessively in autumn due to changes in daylight hours and temperature. The decreased sunlight triggers their bodies to prepare for winter by shedding their summer coat.
Why does a cat shed a lot in autumn? - in detail
Cats are known for their seasonal shedding, with autumn being one of the peak periods for this process. The reason behind excessive shedding during this time is multifaceted and deeply rooted in both physiological and environmental factors.
Firstly, changes in daylight hours significantly impact a cat's hormonal balance. As days grow shorter and nights longer, the decrease in sunlight triggers the production of melatonin, a hormone that regulates the sleep-wake cycle. This hormonal shift can also stimulate the growth of a new coat, which is thicker and denser to better insulate the cat against the colder temperatures ahead. The shedding of the old, thinner summer coat makes way for this new, winter-ready fur.
Secondly, indoor heating systems can exacerbate the shedding process in autumn. While outdoor cats experience a gradual decrease in temperature, indoor cats are subjected to abrupt changes due to artificial heating. This sudden shift from cooler outdoor temperatures to warmer indoor environments can prompt the cat's body to shed its summer coat more rapidly, as it no longer serves the purpose of thermal regulation.
Moreover, the humidity levels in autumn can contribute to increased shedding. Lower humidity can dry out a cat's skin and fur, leading to more hair loss. The dry air also makes it easier for loose hairs to detach from the follicles, resulting in a higher volume of shed fur.
Lastly, the stress hormone cortisol can play a role in seasonal shedding. Changes in routine, such as less outdoor time due to shorter days and cooler temperatures, can elevate a cat's stress levels. Higher cortisol levels have been linked to increased hair loss in cats, further contributing to the autumn shedding phenomenon.
In summary, a cat's excessive shedding in autumn is driven by hormonal responses to decreasing daylight, changes in indoor temperature, lower humidity, and potential stress from routine alterations. Understanding these factors can help cat owners better manage their pets' grooming needs during this seasonal transition.
