When choosing a pet gerbil, it's important to understand the differences between the two main kinds. While the Mongolian Gerbil is the most common, more people are now keeping the unique Fat-Tailed Gerbil. This 2026 guide looks at both kinds, their traits, and how to pick the right friend for your home.
1. The Mongolian Gerbil (Meriones unguiculatus)
Most pet gerbils you see are Mongolian Gerbils. In the wild, they have "Agouti" fur—a mix of colors that helps them hide in the desert. In our homes, they now come in many beautiful colors thanks to careful breeding.
Beautiful Colors
- Solid Colors: These gerbils are one single color all over, like Black, Lilac (grey-purple), or Slate.
- Points: Some gerbils (Siamese and Burmese) have darker fur on their nose, ears, and tail, just like some cats!
- Spots and Patches: These gerbils have pretty white spots or patches on their fur.
2. The Fat-Tailed Gerbil (Pachyuromys duprasi)
Commonly known as the "Duprasi," the Fat-Tailed gerbil is a unique cousin to the Mongolian variety. They look quite different and have very different social needs.
- The Storage Tail: Their thick, club-like tail is where they store fat for energy. A plump, firm tail is the best sign of a healthy Duprasi.
- Calm Nature: They are much more relaxed and slow than Mongolian gerbils. They are known for being very calm and even a bit "sleepy," which makes them wonderful to hold.
- Likes Living Alone: Unlike Mongolian gerbils, who love friends, Duprasi are often happier living alone. Forcing them to live in groups can make them very stressed.
🛡️ Safety Alert: Keep Species Separate
Mongolian and Fat-Tailed gerbils are very different and cannot live together. They communicate in different ways, and putting them in the same home will lead to fighting.
Choosing Your Gerbil
Think about these three things before you decide:
- Friends: If you want to watch a group of pets groom each other and sleep in a big pile, a pair or trio of Mongolian gerbils is the best choice. Explore our social guide for more.
- Energy Level: Mongolian gerbils are busy tunnelers who are always on the move. Duprasi are more relaxed and love a quiet home with deep bedding.
- Their Home: Mongolian gerbils need a "Gerbilarium" setup with lots of bedding so they can build strong tunnels that don't collapse.
Conclusion: A Desert Friend for You
Whether you love the busy social life of the Mongolian Gerbil or the calm, unique look of the Duprasi, both make wonderful pets. Make sure your new friends have the right food and plenty of love and care to live a long, happy life. Check out our other guides for more expert tips.
