The best litter for rabbits is paper-based, aspen shavings, or pellets made from hay or paper

Rabbits are naturally clean animals and will use a litter box if you give them the right setup. The material you put inside matters because rabbits have sensitive respiratory systems and delicate paws. Paper-based litter, aspen wood shavings, and pelleted hay or paper are the safest choices. Avoid clay cat litter, cedar, and pine — these can harm your rabbit's lungs and skin.

The depth should be 2 to 3 inches so your rabbit can dig and bury waste the way they naturally do. Most rabbits will use a box instinctively if the litter feels right under their feet. You may need to try two or three materials to find what your rabbit prefers, since individual rabbits have different habits.

Key Takeaways

  • Paper-based litter, aspen shavings, and hay or paper pellets are safe for rabbit respiratory systems and paws.
  • Clay cat litter, cedar, and pine are toxic or irritating to rabbits and should never be used.
  • Fill the box 2 to 3 inches deep so your rabbit can dig and bury waste naturally.
  • Rabbits often prefer certain materials over others, so you may need to test a few options to find what works for your rabbit.
  • Spot-clean wet litter daily and do a full litter change once or twice a week to keep the box fresh and encourage use.

Paper-based litter: the most common safe choice

Paper-based litter is made from recycled paper and is dust-free, which protects your rabbit's lungs. Brands like Yesterday's News (originally designed for rabbits) and Carefresh are widely available at pet stores and online. These pellets are soft on paws and break down when wet, so they absorb urine well and don't track around the cage.

Paper litter is usually more expensive than wood shavings but lasts longer because it absorbs moisture better. A single bag typically fills a standard litter box for one rabbit for about two weeks with daily spot-cleaning. If your rabbit has a sensitive nose or respiratory issues, paper-based litter is often the first choice because it produces almost no dust.

Aspen shavings: a natural alternative

Aspen wood shavings are safe for rabbits, unlike cedar and pine. They are softer than many wood products and have a natural smell that some rabbits find appealing. Aspen is less absorbent than paper litter, so you will need to change it more often — usually twice a week for a single rabbit — to prevent ammonia buildup from urine.

Aspen shavings are usually cheaper than paper litter and are straightforward to find at farm supply stores and pet retailers. They work well if your rabbit likes to dig and burrow, since the texture encourages natural behavior. The main drawback is that they produce some dust, so if your rabbit has respiratory sensitivity, paper litter may be a better fit.

Hay and paper pellets: combining litter and food

Some rabbits prefer pelleted hay or paper pellets because they can nibble hay while they use the box — a natural behavior for rabbits. Products like Feline Pine (made from pine wood but processed to remove harmful oils) and hay-based pellets work for some rabbits, though they are less absorbent than paper litter. If you choose this route, change the box daily because pellets break down quickly when wet.

Hay pellets are especially useful if your rabbit is picky about litter but loves hay. You can layer hay pellets with a small amount of paper litter underneath to improve absorption. Watch for mold if the box gets damp — hay can mold faster than other materials, so daily cleaning is important.

Materials to avoid completely

Clay cat litter is toxic to rabbits and can cause serious respiratory and digestive problems if inhaled or ingested. Cedar and pine shavings contain oils that damage rabbit lungs and liver, even in small amounts. Clumping litter is dangerous because rabbits may ingest it while grooming, and it can cause intestinal blockages.

Avoid scented litters, litters with added deodorizers, and anything dusty. Rabbits have delicate nasal passages and lungs, and strong chemicals can trigger sneezing, discharge, and breathing problems. Stick to plain, unscented materials designed for small animals or explicitly labeled safe for rabbits.

How to set up and maintain the litter box

Fill the box 2 to 3 inches deep and place it in the corner of the enclosure where your rabbit naturally goes to the bathroom — most rabbits will choose a spot on their own. Spot-clean wet litter and soiled material daily by scooping out clumps. This keeps the box fresh and encourages your rabbit to keep using it.

Do a full litter change once or twice a week, depending on the material and how much your rabbit uses the box. Wipe down the box itself with a damp cloth during the full change to remove urine residue and odor. If your rabbit stops using the box, the most common reason is that it is too dirty — rabbits are fastidious and will avoid a soiled box.

What to do if your rabbit rejects the litter

If your rabbit is not using the box or is eliminating outside it, the litter material may be the problem. Try switching to a different type — for example, if you started with aspen, test paper-based litter instead. Some rabbits are picky and will only use one material, so having two boxes with different litters can help you figure out the preference.

Rabbits also reject litter boxes that are too small, too dirty, or placed in the wrong spot. Make sure the box is at least 12 inches long and 8 inches wide so your rabbit can turn around comfortably. If the box is clean and the right size but your rabbit still avoids it, try moving it to a different corner of the enclosure.

Frequently Asked Questions

Can I use regular cat litter for my rabbit?

No. Clay cat litter is toxic to rabbits and can damage their lungs and digestive system. Clumping litter is especially dangerous because rabbits may ingest it while grooming. Use only materials labeled safe for rabbits or small animals.

How often should I change the entire litter box?

Change the full box once or twice a week, depending on the material and your rabbit's habits. Paper-based litter lasts longer because it absorbs better, so you may only need to change it once a week. Aspen shavings and hay pellets need changing twice a week to prevent ammonia smell and buildup.

What if my rabbit has allergies or respiratory problems?

Use dust-free paper-based litter, which is the gentlest option for sensitive rabbits. Avoid aspen and any wood-based materials, which produce dust. If your rabbit sneezes or has nasal discharge, switch litter when ready and contact a veterinarian who treats rabbits.

Do I need to put hay in the litter box?

You don't have to, but many rabbits like to eat hay while they use the box — it is a natural behavior. You can place a small handful of hay in one corner of the box alongside the litter. This encourages box use and gives your rabbit something to do while eliminating.

Can I mix different litters together?

Yes. Many rabbit owners layer paper-based litter on the bottom for absorption and add hay or aspen on top for comfort and natural digging. Start with 1 to 2 inches of paper litter, then add 1 inch of your rabbit's preferred material. This combination often works well if your rabbit is picky.
