* Seasonal changes: Gerbils molt more frequently in the spring and fall to adjust to the changing seasons. In the spring, they molt their winter coat to make way for a lighter summer coat. In the fall, they molt their summer coat to grow a thicker winter coat.
* Temperature changes: Gerbils also molt in response to changes in temperature. When the temperature drops, they molt to grow a thicker coat that will keep them warm. When the temperature rises, they molt to shed their winter coat and make way for a lighter summer coat.
* Stress: Stress can also cause gerbils to molt. When a gerbil is stressed, its body releases hormones that can trigger the molting process. Stress can be caused by a variety of factors, such as changes in the environment, new animals, or illness.
* Age: As gerbils age, they may molt more frequently. This is because their metabolism slows down and their fur becomes thinner. Older gerbils may also have difficulty grooming themselves, which can lead to matted fur and increased molting.
Molting is a normal process for gerbils and it is not usually a cause for concern. However, if you notice that your gerbil is molting excessively, it is important to take them to the vet to rule out any underlying health problems.
