Causes of Biting

The primary cause of your gerbil’s biting of its cage bars is likely rooted in its instinctual behaviors. Gerbils are social animals, and they need regular social interaction with their owners and playtime activities with their cage mates. If your gerbil is feeling lonely or bored, it may start to bite its cage bars as a way to cope with its feelings.

Additionally, gerbils may bite the bars of their cage out of curiosity and exploration. If your gerbil isn’t getting enough mental stimulation, it may start to explore its cage bars as a way to occupy its mind. In some cases, gerbils may bite their cage bars out of a feeling of frustration or aggression. If your gerbil is feeling anxious or overwhelmed, it may start to bite its cage bars as a way to release its tension.

In order to prevent your gerbil from biting its cage bars, it’s important to provide it with plenty of social interaction, playtime activities, and mental stimulation. Make sure to spend time with your gerbil each day and provide it with plenty of toys and activities to keep it engaged. Additionally, if your gerbil is housed with other gerbils, make sure to provide them with enough space and resources to ensure they aren’t fighting or competing for resources.

Symptoms of Stress

Frequently, if your gerbil is feeling stressed, it may start to bite its cage bars as a way of expressing its anxiety. It is important to recognize the signs of stress in gerbils so you can take proper measures to help them. Stress in gerbils can manifest in various ways. Some of the symptoms are listed below.

Additionally, having two gerbils that are comfortable with each other can help keep your gerbil from becoming lonely or bored. If you think that your gerbil is displaying signs of stress, have your vet examine them to make sure there is no underlying medical condition causing the issue.

Ways to Reduce Stress

To help reduce stress in your gerbil, try providing it with plenty of activities and socializing opportunities. Enrichment activities such as running on a wheel and playing with toys in its cage can help keep your gerbil mentally stimulated. You can also take your gerbil out of its cage for supervised playtime to explore and interact with its environment. Appropriate handling techniques should also be used so your gerbil can become comfortable with being touched and picked up. Additionally, introducing your gerbil to other gerbils can help it build relationships and reduce stress.

To ensure your gerbil is content and stress-free, create a safe and comfortable environment. Keeping its cage in a quiet area away from direct sunlight, loud noises, and other animals can also help. Additionally, make sure the cage is large enough to roam around and has plenty of hiding spots. Lastly, keep your gerbil’s living space clean and clutter-free and provide it with a variety of safe and healthy food options.

Examining the Cage

Moving on from reducing stress, it’s important to make sure the gerbil’s cage is examined. Exploring the gerbil’s space and providing enrichment is key to keeping them happy and healthy. To do this, there are several things to consider:

  1. Size: Make sure the cage is big enough for the gerbil to move around and exercise.
  2. Accessories: Provide toys and objects that will encourage mental stimulation.
  3. Cleanliness: Keep the cage clean to help prevent any health issues.

Evaluating the gerbil’s living space will help to ensure it has everything it needs and to identify any potential problems. Biting the cage bars could be a sign of boredom or even a health issue, so it’s important to pay close attention to the gerbil’s behavior and environment.

If the cage isn’t big enough or lacks stimulating objects, upgrade it with more space or accessories. Additionally, make sure the cage is cleaned regularly and the gerbil has access to fresh food and water.

All of these steps will help to keep the gerbil content and prevent it from biting its cage bars.

Seeking Veterinary Care

If you’ve taken the necessary steps to upgrade the cage and the gerbil still continues to bite its cage bars, it may be time to seek veterinary care. While it’s important to create an environment that provides your gerbil with proper diet and environmental enrichment, a veterinarian can determine if there’s a medical issue that’s causing the behavior. A vet can also assess the gerbil’s overall health and provide valuable insight on how to resolve the issue.

When visiting a veterinarian, it’s important to provide them with a description of the gerbil’s behavior, including how often and how severe the biting is. If possible, it’s also helpful to bring a sample of the gerbil’s diet and the type of bedding that’s used in its cage. This information will help the vet make an accurate diagnosis and provide the best treatment for your gerbil’s specific needs.

The vet may also suggest changes to the gerbil’s environment and diet, such as providing more enrichment activities or switching to a higher-quality food. In some cases, the gerbil may require medication to correct the behavior. While these measures may seem extreme, they can provide long-term relief and help create a healthier, happier life for your gerbil.

Seeking veterinary care is the best way to ensure your gerbil’s long-term health and well-being. By taking the necessary steps and consulting with a veterinarian, you can resolve the issue and prevent it from happening again.


It’s important to take your gerbil’s biting seriously.

While it may seem like a minor annoyance, it can be a sign of underlying stress or anxiety.

Like an iceberg, the causes of a gerbil biting its cage can be hidden beneath the surface.

Examining the cage, reducing stress, and seeking veterinary care are all important steps to take in order to ensure your gerbil’s health and happiness.

Don’t let your gerbil’s biting go unchecked – take the initiative to identify the root cause in order to prevent further issues.
