Do you want your newly adopted rabbit to freely hop around your house, but you're concerned about it leaving little messes all over? There's no need to worry. Rabbits are naturally clean creatures, and training them to use a litter box is easier than you might think. All you need is the right equipment, a properly set-up litter box, and some basic training. Most rabbits catch on to this task fairly quickly. In fact, most adult rabbits that have been spayed or neutered will naturally choose a specific spot to go to the bathroom, so all you need to do is place the litter box in that exact spot.
Steps
Prepare the necessary supplies

Purchase a litter box. Rabbit-specific litter boxes are designed with higher sides at the back to prevent litter from spilling out as the rabbit digs, while the front is lower to allow easy access. You can purchase multiple boxes to place around the house, making it easier to clean and sanitize them when needed.
- You don't have to use a special rabbit litter box. A regular low-sided cat box will work just fine, or you could even use a low-sided cardboard box (though you'll need to replace it frequently, as rabbits tend to chew on cardboard).

Prepare newspaper. Use newspaper to line the litter box to make cleaning easier.
- Most newspapers today are printed with soy-based ink, which is non-toxic for rabbits. However, you should always check before using. The ink may also transfer onto your rabbit's fur, potentially turning it black or gray.

Choose the right type of bedding or compressed wood shavings. You should purchase rabbit-safe bedding, such as paper-based or untreated aspen wood shavings. Avoid using pine or cedar, as these contain oils that can irritate your rabbit’s lungs.
- Do not use cat litter (clay-based or clumping types), as it can cause intestinal blockages if ingested by rabbits.

Buy a rabbit cage. The length of the cage should be three to six times the length of your rabbit's body. The first step in litter box training is to keep your rabbit in the cage, with food, water, and a place for shelter on one side, and the litter box on the other. Limiting their space encourages them to keep their living area clean and use the litter box for their business.

Purchase high-quality hay. Use hay to attract your rabbit's attention by placing it in the litter box. Rabbits enjoy nibbling while they do their business, so this step helps encourage them to use the litter box.

Get a scoop and cleaning supplies. You’ll need a scoop to remove dirty bedding and waste every day. The litter box should be cleaned at least once a week. Special pet-safe cleaning solutions designed for small animals can be used to sanitize the box.
Prepare the Litter Box and Cage

Place a few droppings in the litter box. You can pick up a few of your rabbit's droppings and scatter them in the litter box to help guide them to the correct spot.

Prepare the litter box. Fold the newspaper and line the bottom of the box. Then, pour about 3 cm of compressed wood shavings on top. Rabbits don’t have a habit of burying their waste, so this method will create a distinctive rabbit scent in the box, signaling to your rabbit that this is the proper place for their business.

Place the litter box in the cage. Set the box in one corner of the cage and sprinkle some hay on top. You can also attach a hay rack near the litter box. Since rabbits enjoy nibbling while they use the bathroom, the hay will encourage them to use the litter box.

Prepare a resting spot and food in the cage. Place the bed on the opposite side of the cage, along with food, water, and a hiding spot where your rabbit can feel safe. This provides a comfortable, secure area for your rabbit to retreat to when needed.

Place multiple litter boxes around the house. Set up litter boxes in areas where your rabbit often spends time or plays. The more litter boxes you provide, the higher the chance that your rabbit will use one of them.
- Before introducing your rabbit to the litter boxes, observe and take note of the areas they typically choose to relieve themselves. This is usually a quiet corner somewhere in the house. Once you've identified your rabbit's preferred spot, place a litter box there.
Training Your Rabbit

Start training your rabbit as soon as you bring them home. Adult rabbits usually learn how to use the litter box quicker than younger rabbits (under 4 months old). However, it's never too early to begin litter training. Be sure to set up a litter box right when you bring your rabbit home, and begin teaching them how to use it. With patience, your rabbit will soon learn.
- Typically, after being spayed or neutered, rabbits will select a particular spot to relieve themselves, so all you need to do is place the litter box in that area.
- In the initial stage, if your rabbit goes outside the litter box, scoop up the droppings and place them in the box as a hint for where they should go.

Consider spaying or neutering your rabbit. Unspayed or unneutered adult rabbits tend to have a strong territorial instinct and will mark their territory with scent. This includes leaving urine and droppings around the house to mark their space. Spaying or neutering will make litter training easier, as the need to mark territory will greatly decrease.

Teach your rabbit to use the litter box inside the cage. Initially, this will help restrict your rabbit to the cage along with the litter box, teaching them not to relieve themselves in the areas where they eat and rest. This process will only take a few days, and once your rabbit understands the lesson, you can allow them to roam freely outside the cage.

Allow your rabbit to play outside for short periods. When you let your rabbit play, if you notice them starting to squat to relieve themselves, gently pick them up and place them in the litter box inside the cage. A sign that your rabbit is about to use the litter box is that their tail will slightly raise. This can be hard to spot, but it will help if you catch it in time.
- In the early stages of training, don't let your rabbit stay outside for more than ten minutes at a time, and be sure to observe them closely while playing in the room (so you can correct them before they have the chance to go in the wrong spot). Once your rabbit is using the box regularly, you can relax and give them more freedom.

Reward your rabbit for learning to use the litter box. Don't scold or get angry at your rabbit if they don't use the litter box. Rabbits won't learn this way. Positive reinforcement, like praise, works much better.
- Reward your rabbit with a piece of apple or carrot right after they use the litter box. This will create a positive connection between going to the bathroom and using the box.

Adjust the number of litter boxes. Once your rabbit is consistently using the litter box, you can change the number or relocate the boxes if necessary.
- For example, if your rabbit only uses two litter boxes and ignores the others, you can reduce the number of boxes. If they are not interested in the box but are soiling a corner of the room a meter away, you can move the box to that corner.
Cleaning the Litter Box and Troubleshooting

Clean out the dirty parts of the litter box. Daily, you should scoop out the soiled bedding that has absorbed urine. You can leave the droppings in the box for a day or two to keep the scent, which helps your rabbit recognize the spot and return to it for future bathroom breaks.

Avoid removing all droppings from the litter box. When cleaning the litter box, pay attention to large, moist feces formed from partially digested food. These should be left in the box so your rabbit can eat them again and absorb essential nutrients. Without these droppings, your rabbit could face stomach issues and diarrhea, which, if prolonged, could lead to nutrient deficiencies.

Completely clean the litter box. Once a week, you should empty the bedding from the box and wash it thoroughly. Simply place everything in a plastic bag, tie it up, and throw it away. Use a pet-safe cleaner to scrub the box, rinse it with water, and let it dry. Then, refill the box with fresh newspaper and bedding.
- You can find pet-safe cleaners at your local vet clinic or pet store.

Clean up after accidents. You should accept these mishaps and clean the mess thoroughly to prevent your rabbit from continuing to use that spot. Use a biological cleaner and a soft cloth or sponge to wipe it clean, then rinse with water.
- Don't scold or punish your rabbit. They won't learn anything from punishment except to fear the person doing it.
- When cleaning the mess, be sure to check the colorfastness of your carpet.

Eliminate lingering odors. You can apply a baking soda solution to the carpet, then rinse with water. If the floor is smooth, like tiles or wood, simply clean with rubbing alcohol (isopropyl alcohol).
- Avoid using cleaning products that contain bleach. These contain ammonia, a component of urine, and could actually make the urine smell stronger.
Tips
- Be patient, your rabbit will need some time to learn everything.
- If your rabbit urinates in a corner of the house and doesn't use the litter box, move the litter box to that corner.
- When picking up your rabbit, never grab its neck or ears. The proper way is to place your hand under the chest and support its bottom at the same time.
- If your rabbit stops using the litter box, try restricting its roaming space. Use a pet gate to limit the area until the rabbit begins to use the litter box again.
- Some rabbits prefer a specific type of bedding or litter box. If your rabbit is used to a certain type of box from its previous home, try to get something similar.
- Ensure the rabbit's cage is secure and sturdy.
- The sides of the litter box should be low enough for the rabbit to easily hop in and out.
- Choose a litter box in bright colors, as rabbits are attracted to vibrant hues.
- Speak gently to your rabbit.
- If your rabbit urinates on the floor, you can use vinegar to clean it up.
- If the rabbit is too young, wait until it reaches 4 months of age.
Warnings
- Avoid using bedding made from wood of pine trees (pine, spruce, fir), corn cob bedding, or clay clumping cat litter. Pine and cedar wood shavings release gases that can harm a rabbit's liver and respiratory system. This may lead to chronic asthma and other respiratory issues, reducing the rabbit's ability to absorb necessary medications.
- Inhaling dust from clay cat litter can irritate the rabbit's nose and eyes, and create dust blocks in the lungs, increasing the risk of respiratory diseases. If your rabbit eats clumping cat litter or corn cob bedding, there’s a risk it could form a hard mass in the digestive system, leading to a blockage which can be life-threatening.
- Even if you don’t see your rabbit eating the litter, don’t assume it’s completely safe. Rabbits are meticulous groomers and may ingest any litter stuck to their fur.
