About Gerbil

Gerbils originate from the dry grasslands and deserts of Mongolia and northern China, where they live in family groups and dig extensive burrow systems. They were introduced to the United States in the 1950s as laboratory animals, and their hardiness and charm quickly made them popular as household pets worldwide. Excluding the tail, gerbils measure around 10–13 cm in body length; the tail is roughly equal in length and ends in a distinctive tufted tip. They come in a wide range of color varieties beyond the natural agouti, including white, black, and cinnamon. Curious and energetic, gerbils are active at various times throughout the day and night, making them entertaining to observe. They produce little odor and make minimal noise, making them a practical and appealing choice even in apartment living.

7 things to know before welcoming a Gerbil

1. 1Keep in Pairs or Groups

   Gerbils are naturally social animals that live in colonies in the wild. Keeping a single gerbil can lead to stress and may negatively affect its health. Same-sex pairs or small groups are generally recommended for their wellbeing.

2. 2Sand Bathing for Grooming

   Gerbils keep themselves clean through sand bathing rather than water baths. Providing a container of fine sand (such as chinchilla sand) in the cage a few times a week helps maintain healthy, shiny fur. Avoid washing them with water, as it can cause stress and a dangerous drop in body temperature.

3. 3Expect Digging and Chewing

   Gerbils have a strong instinct to dig and chew. Provide a deep layer of bedding (5–10 cm or more) so they can burrow and tunnel naturally. Offer safe chewing materials such as untreated wooden chews or cardboard tubes regularly to satisfy this behavior and help keep their teeth worn down.

4. 4Never Grab by the Tail

   A gerbil's tail has delicate skin that can strip away if grabbed firmly, a condition known as degloving. Always handle gerbils by gently scooping the whole body with cupped hands, and never restrain them by the tail. Until they are tame, handle them close to a surface to minimize the risk of injury from a fall.

5. 5Prefer Warm, Dry Conditions

   Adapted to desert climates, gerbils are sensitive to high humidity. Aim for an ambient temperature of 20–26°C and relative humidity below 50%. During hot, humid summers, ensure good ventilation and place the cage away from direct sunlight and air-conditioning drafts.

6. 6Prone to Epileptic Seizures

   Gerbils are genetically predisposed to epileptic-like seizures, which can be triggered by sudden sounds, bright lights, or abrupt handling. If a seizure occurs, do not restrain the animal—keep the surroundings quiet and let it rest in a calm, dimly lit space afterward. Consult a veterinarian if seizures become frequent.

7. 7Estimated Setup and Running Costs

   Initial setup costs for a cage, wheel, sand bath container, bedding, and food dish typically run around ¥10,000–¥20,000. Ongoing monthly expenses for pellet food, bedding, and sand are roughly ¥1,000–¥2,000. Since a pair requires little additional space or equipment compared to a single gerbil, keeping two is considered cost-effective.

Frequently asked questions about Gerbil

Q.Can gerbils be kept alone?

A.While it is possible to keep a single gerbil, they are highly social animals that can become stressed without a companion. Keeping same-sex pairs is strongly recommended whenever possible.

Q.What type of cage is best for gerbils?

A.Glass tanks or enclosures that allow for deep bedding are ideal, as they support natural burrowing behavior. Wire cages can pose risks of leg injury and bedding scatter. Aim for a minimum width of around 60 cm to give them adequate space.
