Do Gerbils Change Colors? A Comprehensive Guide for Gerbil Owners!

The coloration of gerbils is determined by their genetic makeup. There are several genes that control coat color, and the combination of these genes determines the color of the gerbil’s fur. The most common colors for gerbils are brown, gray, and black, but they can also be white, cream, and even spotted or pied.

Pigment Production

The color of a gerbil’s coat is determined by the production of two pigments: eumelanin and pheomelanin. Eumelanin is responsible for black and brown coloration, while pheomelanin produces yellow, red, and cream colors. The amount of each pigment produced will determine the overall color of the gerbil’s coat.

Environmental Factors

Environmental factors can also play a role in the coloration of gerbils. For example, exposure to sunlight can cause the fur to fade, while a lack of sunlight can make the fur appear darker. Additionally, changes in temperature and humidity can also affect the color of a gerbil’s coat.

Gerbil Color Changes and What They Mean

Natural Aging

As gerbils age, their coat may naturally change color. For example, a gerbil that was once brown may turn gray as it gets older. This is a normal part of the aging process and is nothing to be concerned about.

Stress and Illness

Stress and illness can also cause changes in a gerbil’s coat color. If your gerbil is experiencing stress or illness, you may notice that its coat appears dull or matted. In some cases, the fur may even fall out. If you suspect that your gerbil is ill, it is important to take it to a veterinarian as soon as possible.

Seasonal Changes

Some gerbils may experience seasonal changes in their coat color. For example, a gerbil may have a darker coat in the winter months and a lighter coat in the summer months. This is a natural response to changes in temperature and daylight.

Color Changes in Pregnant Gerbils

Female gerbils may experience changes in their coat color during pregnancy. This is because the hormonal changes that occur during pregnancy can affect the production of pigments in the fur. If you notice changes in your pregnant gerbil’s coat color, it is nothing to be concerned about.

Common Gerbil Color Variations

Mongolian Gerbils

Mongolian gerbils are the most common type of gerbil and are typically brown or gray in color. They may also have white or cream-colored bellies.

Pied Gerbils

Pied gerbils are characterized by their white patches on their fur. They may have white spots on their face, back, or legs. Pied gerbils can come in a variety of colors, including brown, gray, and black.

Siamese Gerbils

Siamese gerbils are known for their distinctive coloration. They have a dark brown or black “points” on their face, ears, feet, and tail, while the rest of their fur is a lighter color.

Black Gerbils

Black gerbils are a rare color variation. They have a dark black coat and may have a white or cream-colored belly.

Caring for Your Gerbil’s Coat

Proper Nutrition

Proper nutrition is essential for maintaining a healthy coat. Make sure your gerbil is eating a balanced diet that includes plenty of protein and vitamins.

Cleaning and Grooming

Regular cleaning and grooming can help keep your gerbil’s coat healthy and shiny. Use a soft brush to gently groom your gerbil’s fur and remove any dirt or debris.

Environmental Considerations

As mentioned earlier, changes in temperature and humidity can affect the color of your gerbil’s coat. Make sure your gerbil’s habitat is kept at a consistent temperature and humidity level to prevent any unnecessary stress.


In conclusion, gerbils can experience changes in their coat color for a variety of reasons. Understanding the genetic and environmental factors that contribute to these changes can help you better care for your pet. By providing proper nutrition, regular grooming, and a stress-free environment, you can help keep your gerbil’s coat healthy and beautiful.
