Why does a cat shed its fur? - briefly
Cats shed their fur primarily due to changes in daylight and temperature, which signal to their bodies that it's time to replace old or damaged hair with new growth. This process helps cats maintain a healthy coat and regulate their body temperature effectively throughout the year.
Why does a cat shed its fur? - in detail
Cats shed their fur primarily due to changes in daylight, which triggers hormonal responses that regulate their coat growth and shedding cycles. The process is driven by the interaction between light-sensitive cells in the eyes and the pineal gland, which controls the production of melatonin, a hormone that influences hair growth.
In the spring and summer months, as daylight increases, the pineal gland produces less melatonin. This decrease in melatonin levels signals to the cat's body that it is time to shed the thick winter coat. The hair follicles receive this signal and begin to push out the old fur, making way for a lighter summer coat that helps the cat maintain a comfortable body temperature in warmer weather.
Conversely, as the days become shorter in the fall and winter, the pineal gland produces more melatonin. This increase in melatonin levels triggers the hair follicles to start growing new fur, resulting in a thicker coat that provides better insulation against the cold.
Additionally, factors such as stress, poor nutrition, and certain medical conditions can also affect the shedding process. A cat under stress may shed more than usual, while nutritional deficiencies or underlying health issues can lead to excessive hair loss or a dull coat. Regular grooming is essential for managing the shedding process and maintaining the cat's overall health and well-being.
