Paper-based bedding is the top choice for most pet rabbits. It’s soft on their feet, low in dust, highly absorbent, and free of the chemical irritants found in some wood products. But it’s not the only safe option, and the best bedding for your rabbit depends on whether they live indoors or outdoors, how sensitive their respiratory system is, and what you’re using the bedding for (litter box, sleeping area, or both).
Paper-Based Bedding
Recycled paper bedding, especially the type compressed into pellet form, is a favorite among rabbit owners and veterinary professionals alike. It’s highly absorbent and virtually dust-free, which matters because rabbits have delicate respiratory systems that react poorly to airborne particles. Paper bedding is also gentle on their feet, reducing the risk of sore hocks, a painful condition where the skin on the bottom of a rabbit’s feet becomes inflamed or ulcerated.
The main downside is cost. Paper bedding tends to be more expensive per bag than wood-based alternatives, and it needs to be changed frequently enough to keep ammonia levels low. In poorly ventilated enclosures, ammonia from urine can build up quickly. Human workplace standards set irritation thresholds at 25 to 50 parts per million, and rabbit respiratory tracts are at least as sensitive. Regular changes, every few days for the litter area, keep concentrations well below that range.
Compressed Wood Pellets
Compressed pine or softwood pellets are a safe, budget-friendly alternative. This surprises many rabbit owners who’ve heard that pine is dangerous, but the compression and heat-treatment process removes the aromatic oils (phenols) that raise concern in raw pine shavings. These pellets absorb moisture well and break down into sawdust as they get wet, making it easy to see when it’s time for a change.
You can find these sold as small-animal litter or, at a fraction of the price, as wood stove fuel pellets. If you go the fuel pellet route, check that they’re 100% wood with no accelerants or binding agents added. Kiln-dried hardwood pellets are also an option.
Aspen Shavings
Among loose wood shavings, aspen is the go-to safe choice. It’s a hardwood, so it doesn’t contain the phenol compounds found in softwoods like cedar and pine. Aspen shavings provide decent absorbency and a soft surface for resting. They do produce some dust, so look for brands labeled “dust-extracted” or shake out fine particles before adding them to the enclosure.
Straw for Outdoor Rabbits
The Rabbit Welfare Association and Fund recommends good quality soft straw as ideal bedding for warmth, particularly for outdoor rabbits. Straw’s hollow strands trap warm air, creating natural insulation that hay and paper bedding can’t match. It’s also reasonably absorbent.
An important distinction: straw is not hay. Straw is the dried stalk left over after grain crops are harvested. It has very little nutritional value, so it’s not a problem if your rabbit nibbles on it, but it can’t replace hay in their diet. Good quality hay (timothy, orchard grass, or similar) should always be available separately as food. Never substitute one for the other.
What to Avoid
Some common bedding materials are genuinely harmful to rabbits:
- Cedar shavings. Cedar contains high levels of aromatic phenols that can irritate the respiratory tract and have been linked to liver enzyme changes in rodents. Most rabbit care organizations consider cedar unsafe.
- Raw pine shavings. Unprocessed pine carries similar phenol concerns. While one study found that pine shavings used as non-contact bedding (placed below the cage, not directly touched) did not significantly induce liver enzyme changes in rabbits over 14 days, the respiratory irritation from volatile oils remains a reason most experts advise against direct-contact use. Kiln-dried pine with reduced phenol content is sometimes considered acceptable, but paper or aspen is a simpler, safer choice.
- Clumping cat litter. This is one of the most dangerous options. If a rabbit ingests even a small amount during grooming, the clumping material can form rock-hard blockages in the digestive tract that often require surgical removal.
- Wheat-based litters. Rabbits tend to eat these, and the high carbohydrate content can cause obesity, diarrhea, and dangerous bacterial imbalances in the gut.
- Scented litters or bedding. Added fragrances can irritate the respiratory system or discourage your rabbit from using their litter box entirely.
- Sawdust. Too fine and dusty for a rabbit’s sensitive airways.
Protecting Your Rabbit’s Feet
Bedding choice is one of the biggest factors in preventing sore hocks. Rabbits need soft, slightly malleable flooring that mimics the give of natural earth. Wire-bottom cages without solid resting areas are a common cause of foot problems because the wire forces the foot into an unnatural position and concentrates pressure on a small area of skin.
If your enclosure has any wire flooring, always provide a solid resting board or thick layer of bedding on top. For indoor rabbits, soft cotton mats with rubber backing give good traction for healthy movement. In the litter and sleeping areas, a generous layer of paper bedding or straw, deep enough that your rabbit’s feet sink slightly into it rather than hitting the hard surface below, provides the cushioning they need.
Litter Box vs. Sleeping Area
Many rabbit owners use different materials for different purposes. The litter box needs maximum absorbency and easy cleanup, making compressed wood pellets or paper pellets ideal. You can top the pellets with a layer of hay, since rabbits like to munch while they use the litter box (this is normal and actually encourages good litter habits).
The sleeping and resting area prioritizes comfort. Soft paper bedding, straw for outdoor setups, or fleece liners for indoor rabbits all work well here. If you use fleece, wash it frequently and make sure your rabbit isn’t chewing and swallowing the fabric. Ingested cloth fibers are one of the foreign materials known to cause intestinal blockages in rabbits, along with carpet fibers and plastic.
How Often to Change Bedding
Litter areas should be spot-cleaned daily and fully changed every three to four days. Sleeping areas stay cleaner and can go a bit longer, but check them regularly for dampness. Wet bedding breeds bacteria, produces ammonia, and softens the skin on your rabbit’s feet, all of which set the stage for infections and sore hocks. In warm weather or humid climates, you may need to change bedding more frequently. A simple test: if you can smell ammonia when you lean near the enclosure, it’s overdue for a change.
