How Much Bedding Do Hamsters Actually Need?
Direct Answer
Most hamster care guides recommend providing at least 6 inches (15 cm) of bedding, with 8 inches (20 cm) or more being ideal for allowing hamsters to dig and build burrows.
Hamsters are natural burrowers, so deeper bedding helps them express natural behaviors such as tunneling, nesting, and hiding. When bedding is too shallow, hamsters may become stressed or try to dig constantly in corners of their enclosure.
Key Takeaways
- Minimum bedding depth: about 6 inches (15 cm)
- Recommended depth: 8 inches (20 cm) or more
- Deep bedding allows hamsters to dig natural tunnels
- Paper bedding and aspen are commonly recommended materials
- Burrowing behavior is essential for hamster wellbeing
Why Hamsters Need Deep Bedding
Hamsters naturally live underground.
In the wild, they create complex burrow systems that include multiple chambers used for sleeping, nesting, and storing food. Because of this instinct, hamsters constantly dig when enough substrate is available.
Providing deep bedding in captivity allows hamsters to recreate some of these natural behaviors. Bedding gives them places to burrow, hide, and build nests inside their enclosure. Read our guide: How Many Hideouts Does a Hamster Need?
Without enough bedding to dig into, hamsters may struggle to express these behaviors and can become bored or stressed.
Recommended Bedding Depth
Different care guides recommend slightly different depths, but most agree that hamsters need several inches of substrate for burrowing.

According to hamster care guidance, at least 6 inches of bedding in one part of the enclosure helps hamsters burrow and dig naturally.
Other hamster enclosure guides recommend around 8 inches (20 cm) or more so hamsters can properly construct tunnels and underground nests.
Signs Your Hamster Needs More Bedding
If bedding is too shallow, hamsters often show behaviors that indicate frustration.
Common signs include:
- digging constantly in corners
- chewing cage bars
- trying to escape the enclosure
- destroying bedding piles
These behaviors often appear when hamsters try to build a burrow but cannot dig deep enough.
Providing deeper bedding can often reduce these stress behaviors.
Best Types of Bedding for Hamsters
Not all bedding materials are suitable for burrowing.
Commonly recommended bedding types include:
Paper bedding
Soft, absorbent, and excellent for nesting and burrowing.
Aspen shavings
A safe wood bedding option that provides good airflow.
Mixed substrates
Some owners mix paper bedding with hay or other substrates to improve tunnel stability.
Paper-based bedding is widely recommended because it helps hamsters build stable tunnels while remaining soft and comfortable.
Avoid cedar or pine bedding, which may contain oils that can be harmful to hamsters.
How to Set Up Bedding in a Hamster Enclosure
A common enclosure design is to create a bedding depth gradient.
For example:
- Deep side: 8–10 inches of bedding for burrowing
- Middle area: medium bedding depth
- Wheel side: shallow bedding for stability
This setup allows hamsters to dig tunnels while keeping heavy accessories stable.
Some owners also place hideouts or platforms above deep bedding areas so hamsters can build underground chambers beneath them.
Why Bedding Depth Matters
Deep bedding is not just about comfort—it supports natural behavior.
Hamsters use bedding to:
- dig tunnels
- build nests
- store food
- hide from perceived danger
Because hamsters are prey animals, having a place to dig and hide helps them feel safer in their environment.
When hamsters can burrow naturally, they are often calmer and more active at night.
Frequently Asked Questions
Do hamsters need bedding if they already have a hideout?
Yes. Hideouts provide shelter above ground, while bedding allows hamsters to dig tunnels and build underground nests. Both are important for creating a natural and comfortable environment.
Can hamsters have too much bedding?
Generally no. As long as the enclosure has proper ventilation, deeper bedding allows hamsters to build more complex tunnels and burrows.
What bedding is safest for hamsters?
Paper bedding and aspen shavings are commonly recommended because they are soft, absorbent, and safe for small animals.
How often should hamster bedding be changed?
Most hamster enclosures only need spot cleaning weekly, with a deeper clean every few weeks depending on enclosure size.
Why does my hamster sleep underground?
Hamsters instinctively sleep in burrows because enclosed spaces help them feel safe and protected.
Final Thoughts
Providing enough bedding is one of the most important parts of creating a healthy hamster habitat.
Most care guides recommend at least 6 inches (15 cm) of bedding, while 8 inches (20 cm) or more allows hamsters to dig proper tunnels and express natural burrowing behavior.
By offering deep bedding along with hideouts and enrichment, you can create an enclosure that helps hamsters feel secure and behave more naturally.
