Gerbils are very social and busy animals that love to live with friends. Understanding their unique habits, like why they drum their feet or why they dig so much, will help you build a great relationship with them. In 2026, we focus on helping your gerbils live in a way that satisfies their natural instincts so they stay happy and friendly.
The Importance of Friendship: Living in Pairs
In the wild, gerbils live in large family groups. Because of this, they must live with at least one other gerbil friend. A single gerbil can become very lonely and sad. Having a companion to sleep with and groom is essential for their happiness.
Understanding "Declanning"
Sometimes, two gerbils that have lived together for a long time might suddenly start fighting. This is called "declanning." It often happens because their home smells different (like after a deep clean) and they don't recognize each other anymore.
- The "Ball of Death": If you see your gerbils rolling together in a tight ball and fighting, you must separate them immediately. This is a very serious fight and they will need to be reintroduced slowly using a "split tank" method.
The Famous Foot Thump
Have you ever heard your gerbil drumming their back feet loudly on the floor? This is called "foot thumping."
- The "Thump" Warning: If a gerbil feels scared, they will thump their back legs on the ground. This sounds like a tiny drum! It is a signal to the rest of the group that something might be dangerous. You'll often hear this if they are startled in their cage.
- Social Grooming: Gerbils show love by gently nibbling on each other's ears and necks. This helps build a strong bond and keeps the group peaceful.
Friendship Sign: Mutual Grooming
The best sign that your gerbils are happy together is when they groom each other. You will see them nibbling and cleaning each other's ears and necks. This "social grooming" is how they show they are best friends and part of the same group.
Master Diggers and Builders
Gerbils are made for digging tunnels! If you see your gerbil digging in the corner of their cage for a long time, it is because they are trying to make a burrow.
- How to Help: Give them very deep bedding (at least 10–12 inches). This lets them make real tunnels that won't collapse, which makes them feel safe and happy.
The Secret Scent Map
Gerbils have a small scent gland on their belly. You might see them rubbing their tummy on their toys or hideouts. They are "marking" their home with their own special scent so they know where everything is. This is why it is best not to use strong-smelling cleaners, as it can confuse your gerbils and make them nervous.
When are They Active?
Gerbils aren't just active at night; they are busy in bursts throughout the day and night! They will play for a few hours, then nap for a few hours. The best time to play with them is when they are naturally active and curious.
Conclusion: Building a Great Bond
By respecting your gerbils' need for friends and their love for digging, you will have a pair of very happy and entertaining pets. Watching them work together to build tunnels is one of the best parts of owning gerbils! Check out our other guides for more tips on cages, food, and gerbil health.
