Why does the cat shed a lot in autumn? - briefly
The change in daylight hours and temperature in autumn triggers cats' hormones to stimulate shedding, leading to increased hair loss during this season. Additionally, the shorter days prompt cats to grow thicker coats for winter, causing them to shed their lighter summer fur.
Why does the cat shed a lot in autumn? - in detail
Cats are known for their seasonal shedding, and autumn is one of the peak times when this occurs. The reason behind this phenomenon lies in the interplay between light exposure and hormonal changes.
During the summer months, cats experience longer days with increased sunlight. This change in daylength triggers a response in the cat's body that leads to an increase in melatonin production. Melatonin is a hormone that regulates various biological processes, including the hair growth cycle. In cats, melatonin signals the hair follicles to enter a resting phase, resulting in less shedding during summer.
As autumn approaches, the days start to shorten, and the amount of sunlight decreases. This change in light exposure causes a decrease in melatonin production. With reduced melatonin levels, the hair follicles exit the resting phase and begin a new growth cycle. During this transition, the old fur is shed to make way for the new coat that will grow in preparation for the colder winter months.
Additionally, cats may experience a slight increase in stress hormones during the autumn season due to changes in their environment or routine. Stress can also contribute to increased shedding, as it affects the hair growth cycle and promotes the release of old fur.
In summary, the cat's body responds to changes in daylength by adjusting melatonin production, which in turn regulates the hair growth cycle. The decrease in sunlight during autumn triggers the shedding process, allowing cats to shed their summer coat and grow a new one suitable for the upcoming winter season.
