Empty and refill the litter box every day
Remove the soiled litter and hay from the box each morning or evening — whichever time your rabbit uses it most. Rabbits are creatures of habit and will use the same corner of their enclosure repeatedly, so you will see clumping in one spot. Scoop out that section along with any wet bedding underneath it.
Replace the removed litter with fresh material. Most rabbit owners use pelleted litter (made from compressed wood or paper) in the bottom, topped with hay. The hay serves double duty: rabbits eat from it while they sit in the box, and it absorbs moisture. This daily swap keeps odor down and prevents ammonia buildup, which can irritate your rabbit's respiratory system.
If your rabbit is young or still learning box habits, you may need to empty and refill twice daily. Watch for the pattern — once you see where accidents happen, you can adjust the box size or position to match their preference.
Key Takeaways
- Empty soiled litter and hay daily, focusing on the corner where your rabbit urinates most, and replace it with fresh pelleted litter and hay.
- Wash the box itself with hot water and mild soap once a week to remove urine stains and bacteria that daily scooping cannot reach.
- Use pelleted litter (wood or paper-based) rather than clay or clumping cat litter, which can cause digestive problems if your rabbit ingests it.
- Ammonia buildup from urine damages your rabbit's lungs and nose, so daily cleaning is not optional even if the box looks dry on top.
- Keep a second litter box clean and ready so your rabbit always has a sanitary option while you wash the first one.
Wash the box with hot water and soap once a week
Daily scooping removes fresh waste, but urine soaks into the plastic or ceramic and leaves stains and bacteria. Once a week, take the box out of the enclosure and scrub it with hot water and a small amount of mild dish soap. Use a brush or cloth to reach the corners where urine pools.
Rinse thoroughly with clean water until no soap residue remains — rabbits are sensitive to chemical smells and will avoid a box that smells like detergent. Dry the box completely before refilling it. If the box has deep stains or a persistent smell after washing, soak it in hot water for 15 to 20 minutes before scrubbing.
If you have more than one rabbit or a rabbit that produces very strong urine, wash the box twice a week instead. Some owners keep two boxes and rotate them, washing one while the other is in use.
Choose the right litter material
Pelleted litter is the safest choice for rabbits. It is made from compressed wood shavings, paper, or aspen and absorbs urine well while producing minimal dust. Brands like Carefresh, Feline Pine, and Oxbow are widely available and cost between $10 and $20 per large bag, depending on your location and the brand.
Never use clay-based cat litter or clumping litter. Rabbits dig in their boxes and inhale dust, and they may eat small amounts of litter while grooming. Clay and clumping formulas can cause intestinal blockages and respiratory problems. Avoid cedar and pine shavings as well — both release oils that damage rabbit lungs.
Pair the pelleted litter with hay (timothy, orchard grass, or meadow hay) in the top layer. The hay absorbs additional moisture and gives your rabbit something to nibble while using the box, which is natural behavior. This combination keeps the box drier and fresher longer than litter alone.
Handle odor and ammonia buildup
Rabbit urine has a strong smell, especially from males and unspayed or unneutered rabbits. The smell comes from ammonia, which builds up quickly in a closed space. If you notice a sharp, chemical odor near the litter box, ammonia levels are too high — this is a sign you need to clean more often or use more litter material.
Ammonia irritates the mucous membranes in your rabbit's nose, eyes, and lungs. Over time, exposure can lead to respiratory infections and chronic snuffling. Daily cleaning is the only reliable way to prevent this. If the room itself smells like ammonia, open windows and consider adding a second litter box so your rabbit always has a clean option.
Some owners add a thin layer of baking soda under the pelleted litter to absorb odor, though this is optional. Do not use scented litters or air fresheners — rabbits find strong smells stressful and may stop using the box.
Position and size the box for your rabbit's habits
Rabbits will use a litter box only if it suits their size and location. The box should be large enough that your rabbit can turn around, stretch out, and sit comfortably without their rear end hanging over the edge. A rabbit that cannot fit properly will go outside the box instead.
Place the box in the corner where your rabbit naturally goes to the bathroom. Most rabbits choose one or two spots in their enclosure. If your rabbit is already using a corner, put the box there. If they are new to litter training, place the box in a quiet corner away from their sleeping area and food bowl.
If your rabbit is using the bathroom outside the box, the problem is usually size or location, not stubbornness. Try a larger box or move it to a different corner. Some rabbits need a box with a low entry point; others prefer one with higher sides for privacy. Observe your rabbit's behavior and adjust accordingly.
Clean up accidents outside the box
Even a well-trained rabbit will have accidents, especially during hormonal cycles or if the box is dirty. When you find urine or feces outside the box, clean it when ready with an enzymatic cleaner made for pet urine. Regular soap and water will not break down the urine compounds, and your rabbit will smell the old spot and use it again.
Enzymatic cleaners contain bacteria that digest urine and feces at the molecular level, removing both the mess and the scent marker. Brands like Nature's Miracle and Rocco & Roxie work on most surfaces. Spray the area, let it sit for 10 to 15 minutes, and wipe clean. This prevents your rabbit from establishing a second bathroom spot.
If accidents happen repeatedly in the same location, move the litter box to that spot. Your rabbit is telling you that location works better for them than the current box placement.
Maintain the box between deep cleans
Between weekly washes, keep the box in good condition by removing wet spots daily and topping up hay. If you notice the box developing cracks or the plastic becoming discolored despite regular washing, it is time to replace it. A damaged box is harder to clean and can harbor bacteria in crevices.
Litter boxes for rabbits are inexpensive — most cost $5 to $15 — so replacing one every 1 to 2 years is normal wear. Corner litter boxes designed specifically for rabbits fit neatly into enclosure corners and are easier to clean than makeshift containers.
Keep cleaning supplies (hot water, mild soap, a brush, and enzymatic cleaner) in one place so you can clean the box quickly and consistently. The easier you make the routine, the more likely you are to stick with it.
Frequently Asked Questions
How often should I completely change the litter?
Empty and refill the box daily, removing all soiled litter and hay. Wash the box itself with soap and water once a week. If your rabbit is very young or still learning, you may need to change it twice daily until habits are established.
Can I use newspaper or cardboard in the litter box?
Newspaper and cardboard absorb urine but do not control odor as well as pelleted litter. They also break down quickly and can be messy. Pelleted litter is more effective and easier to manage, though you can layer newspaper under the pellets to catch leaks and reduce waste.
What if my rabbit stops using the litter box?
A sudden change in litter box habits usually means the box is dirty, too small, or in the wrong location. Check that you are cleaning daily and that the box is large enough for your rabbit to turn around. If the box is clean and properly sized, try moving it to a different corner or adding a second box. If the problem persists, consult a veterinarian to rule out urinary tract infections or other health issues.
Is it normal for rabbits to poop outside the litter box?
Rabbits naturally drop feces while moving around, so some poops outside the box is normal. However, most rabbits will urinate in the box consistently if it is clean and well-placed. If your rabbit is leaving piles of feces in specific spots, move the litter box to that location or add a second box there.
Do I need to use hay in the litter box if I feed hay separately?
Yes. Rabbits eat hay while sitting in the litter box — it is natural behavior and keeps them in the box longer, reinforcing the habit. Even if you provide hay in a separate feeder, include it in the litter box as well. This also helps absorb moisture and keeps the box fresher between cleanings.
