What’s the Best Litter for My Pet Rat?

Choosing the right litter for your pet rat is more important than it might seem. A good litter not only keeps their cage clean and odor-free, but also plays a big role in your rat’s comfort, health, and overall well-being.
Rats are clean, intelligent animals, and their habitat needs to reflect that. The type of bedding or litter you choose will affect everything from air quality to how much your rat enjoys digging and nesting - so it’s worth getting right.
Let’s break down the best (and worst) litter options, and how to make the best choice for your furry companion.
Why Litter Matters
Litter serves several key functions in your rat’s enclosure:
- Absorbs urine and controls odor
- Keeps the cage cleaner and easier to maintain
- Encourages natural behaviors like digging and burrowing
- Supports respiratory health by minimizing dust and irritants
Because rats have sensitive lungs and are prone to respiratory issues, choosing a safe, low-dust, non-toxic litter is essential - not optional.
Best Litter Options for Pet Rats
1. Paper-Based Bedding
This is one of the safest and most popular choices for pet rats.Opt for brands that use recycled paper that’s:
- Soft and comfortable
- Highly absorbent
- Low in dust
- Free from perfumes or harmful chemicals
It’s gentle on sensitive feet, excellent at controlling odor, and a top pick for many rat owners - especially for those with allergy-prone pets.
2. Aspen Shavings
Unlike pine or cedar, aspen wood doesn’t contain harmful aromatic oils and is considered safe for small animals.
Pros:
- Natural and relatively inexpensive
- Offers decent absorbency
- Good for digging and nesting behavior
However, it may not be as effective at controlling odor as paper-based options - so frequent cleaning is still a must.
3. Hemp Bedding
A newer favorite among small pet enthusiasts, hemp bedding is:
- Soft and cozy
- Extremely absorbent
- Naturally odor-controlling
- Biodegradable and eco-friendly
- Very low in dust
Though it can be slightly more expensive, many rat owners feel the added comfort and air quality are worth it - especially for rats prone to respiratory issues.
What to Avoid
✖ Pine and Cedar Shavings
Although commonly sold in pet stores, these wood shavings contain aromatic oils that can irritate your rat’s lungs and liver, leading to serious health problems over time. Best to steer clear altogether.
✖ Clumping Cat Litter
Rats are curious and often chew on their bedding. If they ingest clumping litter, it can expand inside their digestive tract, causing blockages and life-threatening complications.
✖ Corn Cob Litter
It may seem like a natural option, but corn cob litter:
- Molds easily when damp
- Doesn’t control odors well
- Can be eaten, posing a risk of blockages or fungal infections
Overall, it’s not a safe or effective choice.
So, What’s Best for Your Rat?
When it comes to choosing the best litter for your pet rat, focus on safety, absorbency, low dust, and comfort. Top choices include:
- Paper-based bedding - soft, clean, and great for odor control
- Aspen shavings - natural and safe, but needs regular cleaning
- Hemp bedding - a soft, eco-friendly option that’s gentle on sensitive systems
Your rat’s environment plays a huge role in their health and happiness - and picking the right litter is a great first step in creating a safe, enriching space they can thrive in.
