The best litter box material for rabbits is paper-based or aspen shavings, not clay or clumping litter
Rabbits need absorbent, dust-free litter that won't harm them if they eat it — which they will, since rabbits often nibble the material in their box. Clay litter, clumping litter, and cedar or pine shavings are toxic to rabbits and can cause respiratory problems or digestive blockages. Paper-based litters, aspen shavings, and pelleted litters made from recycled paper or wood are safe choices that absorb urine well and control odor.
The litter should be at least 2 to 3 inches deep so your rabbit can dig and burrow, which is natural behavior. Rabbits are naturally clean animals and will use a litter box consistently if the material feels right to them, so the texture matters as much as the safety.
Key Takeaways
- Paper-based litters and aspen shavings are safe for rabbits; clay, clumping, cedar, and pine litters are toxic and can cause serious illness.
- Fill the box 2 to 3 inches deep to let your rabbit dig naturally and absorb urine fully.
- Add a layer of hay on top of the litter, since rabbits eat hay while they use the box and this keeps them in the habit of using it.
- Scoop out wet spots and droppings daily and do a full litter change once or twice a week, depending on box size and number of rabbits.
- If your rabbit stops using the box, the litter type may be the reason — try a different material before assuming a behavior problem.
Paper-based litters work best for most rabbit owners
Paper-based litters are shredded or pelleted newspaper, cardboard, or recycled paper products. Brands like Carefresh, Aspen Animal Bedding, and store-brand paper litters are widely available and cost between $8 and $15 for a large bag. They absorb urine well, produce little dust, and are safe if your rabbit eats small amounts.
Paper litters are softer on your rabbit's feet than some alternatives, which matters because rabbits spend time sitting in the box. They also tend to control odor better than aspen alone, especially in smaller boxes or with multiple rabbits. The main drawback is that they can track — small pieces stick to fur and get carried around the room — but this is minor compared to safety.
Aspen shavings are a budget option if you buy the right kind
Aspen shavings are safe for rabbits, unlike cedar and pine, which contain oils that damage rabbit lungs and livers. Aspen is softer than hardwood shavings and costs less than paper litter — usually $5 to $10 for a large bag. It absorbs reasonably well and many rabbits like the texture for digging.
The catch is that aspen produces more dust than paper litter, which can irritate sensitive rabbits' respiratory systems. It also doesn't control odor as effectively, so you'll need to change it more often. If you use aspen, buy the fine shaving variety rather than coarse chips, and watch for sneezing or wheezing, which signals your rabbit may need a switch to paper litter.
Add hay on top of the litter to reinforce box use
Rabbits eat while they use the litter box — this is normal behavior and helps keep them in the habit of using it. Lay a layer of timothy hay, orchard grass, or other grass hay on top of the litter. Your rabbit will nibble the hay, do their business, and stay in the box longer, which reinforces the routine.
This also means your rabbit is eating hay in the right place, which is where you want them to spend time anyway. Change the hay daily along with spot-cleaning, so it stays fresh and doesn't get soiled. If hay gets wet or packed down, remove it and replace it.
Avoid these materials entirely
Clay litter and clumping litter are designed for cats and are dangerous for rabbits. If your rabbit ingests clay dust or clumps, it can block their digestive system and cause serious illness or death. Clay also produces dust that harms rabbit lungs.
Cedar and pine shavings contain aromatic oils called phenols that are toxic to rabbits. Even small amounts can damage the liver and respiratory system. These materials are sometimes sold as "safe bedding" but are not safe for rabbits under any circumstances.
Corn cob litter is sometimes marketed as natural, but it can mold in humid conditions and cause respiratory infections. It also doesn't absorb urine as well as paper or aspen.
Sawdust is too fine and produces excessive dust. It also compacts when wet and doesn't absorb urine well.
How often to change the litter and spot-clean
Spot-clean the litter box daily by removing wet spots, clumps, and soiled hay. This keeps the box fresh and encourages your rabbit to keep using it. A rabbit that sits in a dirty box may start using other areas of their space instead.
Do a full litter change once or twice a week, depending on the box size and how many rabbits use it. A single rabbit in a large box may only need a full change once a week. Two rabbits or a rabbit in a small box may need a change twice a week. If odor builds up between changes, change it more often — a clean box is one of the easiest ways to keep your rabbit healthy and prevent behavior problems.
What to do if your rabbit stops using the litter box
If your rabbit suddenly avoids the box or uses it inconsistently, the litter material is often the reason. Rabbits are picky about texture and will refuse a box if the litter feels wrong. Try switching to a different type — if your rabbit has been using aspen, try paper litter, or vice versa.
Also check that the box is clean, large enough, and in a quiet corner. A box that's too small, too dirty, or in a high-traffic area may be rejected. If your rabbit is older or has mobility issues, a box with lower sides makes it easier to get in and out. Once you've ruled out the litter type and box setup, a veterinarian can check for urinary tract infections or other health issues that affect litter box habits.
Frequently Asked Questions
Can I use regular newspaper as litter?
Plain newspaper alone doesn't absorb urine well enough and will get soaked quickly, creating a wet, smelly box. Shredded paper litter is made from newspaper but is processed to absorb better. If you're in a pinch, shred newspaper and layer it thickly, but switch to proper paper litter as soon as you can.
Is pelleted litter better than shredded paper litter?
Pelleted litter (made from compressed paper or wood) absorbs very well and controls odor strongly, but some rabbits find it uncomfortable on their feet or don't like the texture for digging. Shredded paper is softer and more natural-feeling. Try both and see which your rabbit prefers — preference varies by individual rabbit.
What if my rabbit is allergic to paper litter?
Allergies to paper litter are rare, but signs include sneezing, watery eyes, or scratching around the face. If you suspect an allergy, switch to aspen shavings or pelleted litter and watch for improvement over a few days. If symptoms continue, see a veterinarian, as the issue may be dust sensitivity rather than an allergy to the material itself.
Can I mix two types of litter in the same box?
Mixing litter types is fine and can help you transition from one to another. Start with mostly the old litter and gradually add more of the new type over a week or two. This gives your rabbit time to adjust to the new texture without rejecting the box entirely.
Do I need a litter box liner?
Liners are optional. They make cleanup easier by letting you lift out the whole liner and dispose of it, but some rabbits dislike the plastic texture and may avoid the box. If you use a liner, make sure it's sturdy enough that your rabbit can't chew through it and ingest plastic.
