The best bedding for rats is dust-extracted paper-based bedding or cellulose chips, with plain paper or tissue for nests. Non-aspen wood chips that are dust-extracted and washable fleece liners can work too. Avoid sawdust, pine or cedar chips, cotton wool and scented or coloured bedding: Blue Cross, the RSPCA, PDSA and Woodgreen all warn against them.
How the comparison works
The tool lists eleven bedding and nesting choices. Each one is marked "Good choice", "Use with care" or "Avoid", from what four UK charities say, and tagged with what it does well: low dust, soaking up wee, easy spot-cleaning, nesting, washing or foraging.
Tap what matters most in your cage and the list re-orders itself. Bedding with the most matches rises to the top and is highlighted, options that match nothing fade back, and anything marked "Avoid" always stays at the bottom, however it scores. Your choices stay in the page address, so you can copy the link to come back to the same list.

Why dust and smell matter
Rats breathe close to their bedding all day and night. PDSA says dusty bedding such as wood chippings or sawdust can cause breathing problems, and Woodgreen says sawdust and most standard pet-shop wood shavings can harm a rat's skin and airway. The RSPCA asks for bedding that is not dusty, fragranced or coloured, and warns that very absorbent bedding can change the humidity in the cage. Blue Cross and the RSPCA say fluffy stuffing-type bedding can wrap round feet and limbs.
Keeping bedding fresh
- Spot-clean wet or dirty patches during the week, and clean the whole cage about once a week, as the RSPCA suggests.
- Leave a little clean, used nesting material behind after a big clean, so the cage still smells like home.
- Give a generous layer of bedding, and plenty of plain nesting material so rats can build their own nests.
- Wash fleece often, put an absorbent layer underneath, and remove anything chewed into loose threads.
Common questions
What is the best bedding for rats?
Dust-extracted paper-based bedding and cellulose chips are the safest everyday choices, recommended by Blue Cross and the RSPCA. Add white tissue, shredded plain paper or paper strips for nesting. A washable fleece liner, as PDSA suggests, works well on shelves and in cages you spot-clean often.
Is wood shavings bedding safe for rats?
Most standard wood shavings and sawdust are not. Woodgreen says they can harm a rat's skin and airway, and PDSA says dusty wood chippings can cause breathing problems. Blue Cross and the RSPCA do list non-aspen wood chips that are dust-extracted, so if you use wood, choose those and never sawdust, pine or cedar.
Is aspen bedding safe for rats?
Advice differs. Aspen is widely sold, especially in the US, but the RSPCA lists it among dusty beddings to avoid. We follow the RSPCA and suggest paper-based bedding, cellulose chips or dust-extracted non-aspen chips instead.
Can I use fleece instead of bedding for rats?
Yes, PDSA suggests a washable fleece liner as an alternative to paper bedding. Put an absorbent layer underneath, wash it often, and remove anything chewed into loose threads. Still give paper or tissue for nesting, and a dig box or loose bedding area so rats can forage and dig.
Is cotton wool or fluffy bedding safe for rats?
No. Blue Cross, the RSPCA, PDSA and Woodgreen all warn against cotton wool and fluffy stuffing-type bedding. The strands can wrap round toes and limbs and cause serious injury. Give plain white tissue or shredded plain paper for nesting instead.
Can rats have newspaper as bedding?
PDSA lists newspaper among things not to use in a rat's cage. Plain paper bedding made for small pets is a better choice for the main layer. Shredded plain, uninked paper is fine as nesting material, as the RSPCA suggests.
