1. Nesting Material: Gerbils are naturally burrowing creatures. They like to create nests and tunnels. They may be kicking sawdust out to make space for their nest, or to build tunnels and burrows.
2. Boredom: If your gerbil is bored, he may be kicking sawdust out of frustration or to entertain himself.
3. Dust Bath: Gerbils need to dust bathe regularly to keep their fur clean and healthy. They might be kicking the sawdust around to create a dust bath.
4. Cleanliness: Gerbils are very clean animals and may be kicking out sawdust to keep their cage clean.
5. Cage Size: A small cage can make your gerbil feel cramped, leading to him kicking out bedding as a form of stress relief.
What to do:
* Provide more bedding: Make sure your gerbil has enough bedding to burrow and build a nest.
* Offer enrichment: Give your gerbil plenty of things to do, such as chew toys, tunnels, and a wheel to keep him entertained.
* Dust bath: Ensure you provide a separate dust bath area for your gerbil.
* Regular cleaning: Clean your gerbil's cage regularly, but avoid changing all the bedding at once, as this can make him feel insecure.
* Consider a larger cage: If your gerbil is still kicking out bedding, you may need to consider a larger cage.
If you're concerned about your gerbil's behavior, it's always best to consult with a veterinarian or a qualified exotic animal expert.
