Can You Use Cat Litter for Rabbits?

Many rabbit owners wonder if it's okay to use regular cat litter for their bunnies. The short answer is no – cat litter is not recommended for rabbits. There are a few key reasons why cat litter should be avoided for rabbits:

  • Cat litter can cause intestinal blockages. The clumping agents used in many cat litters can expand inside a rabbit's intestines and cause a blockage. This can be fatal if not treated quickly.
  • Cat litter dust poses a respiratory risk. Rabbits have sensitive respiratory systems and are prone to respiratory infections. The dust in clay cat litters can irritate their airways.
  • Ingredients may cause digestive upset. Cat litters often contain perfumes, deodorizers, and chemicals that can be harmful if ingested by rabbits.

Rabbits have very different bathroom habits and litter needs compared to cats. They tend to eat while they use their litter box, so ingredients must be completely safe if accidentally ingested. The litter also needs to be very absorbent to handle a large volume of urine.

While cat litter may seem like an easy solution, it's much safer to use a litter made specifically for rabbits. There are several rabbit-safe litters available that provide the right absorbency and safety for bunnies.

Intestinal Blockages

One of the biggest risks of using clumping cat litter with rabbits is intestinal blockages. Many clumping clay litters and crystal gel litters contain swelling agents such as calcium bentonite or silica gel. When these litters come into contact with liquid, they form a solid clump by absorbing the moisture.

While the clumping action is great for scooping a cat's litter box, it can be extremely dangerous for rabbits. Rabbits often ingest some of their litter while eating hay directly from the litter box. If a rabbit ingests clay or crystal litter that contains a clumping agent, the litter can rapidly expand inside the gastrointestinal tract when it comes into contact with moisture.

This puts immense pressure on the intestinal walls and causes a blockage. A complete intestinal blockage is fatal within 24-48 hours if not treated, as food cannot pass through the digestive system. Partial blockages are also extremely dangerous, as bacteria can build up behind the blockage and cause potentially fatal septicemia.

Some signs of an intestinal blockage in a rabbit include:

  • Loss of appetite
  • Lethargy, depression
  • Smaller and fewer fecal droppings
  • Straining to pass stool with no results
  • Bloated or distended abdomen

If a blockage is suspected, immediate veterinary care is necessary. The blockage may be visible on an X-ray. Treatment usually involves surgery to remove the obstruction as soon as possible. However, the prognosis for rabbits with an intestinal blockage is often poor, even with rapid treatment. Prevention is crucial by avoiding clumping cat litters.

Respiratory Issues

Another reason cat litter is not suitable for rabbits is the potential respiratory risks from dust. Rabbits have very sensitive respiratory systems. Their lungs are more fragile than other animals, putting them at higher risk for respiratory infections.

Clay cat litters in particular generate a lot of fine dust that gets stirred up whenever the rabbit scratches in the litter box. Breathing in this litter dust over time can cause chronic nasal and respiratory irritation.

For rabbits already prone to respiratory issues, the dust can exacerbate sneezing, coughing, and sniffling. The dust may also worsen underlying respiratory infections. Common respiratory conditions in rabbits include:

  • Pasteurellosis – bacterial infection caused by Pasteurella multocida
  • Encephalitozoon cuniculi – fungus that can cause respiratory signs
  • Bordetella bronchiseptica – bacterial agent of “snuffles” in rabbits
  • Aspergillosis – fungal infection of the nasal passages and lungs

All of these conditions can be aggravated by dusty litter. The dust provides an irritant that allows bacteria and fungi to take hold more easily in the airways. Chronic respiratory irritation can progress to pneumonia in severe cases.

To avoid respiratory risks, use a dust-free litter for rabbits. Wood stove pellets make an inexpensive dust-free option. Paper-based litters or natural litters like aspen shavings are also low-dust choices.

Digestive Problems

A third issue with using cat litter for rabbits is the potential for digestive upset. Since rabbits often eat while using their litter box, any harmful litter ingredients can be ingested.

Many standard clay cat litters contain added scents, deodorizers, and chemicals. Clumping litters also include gelling agents that could cause adverse effects if eaten. After ingesting these substances, rabbits may experience:

  • Loss of appetite
  • Reduced fecal output
  • Soft stools or diarrhea
  • Intestinal gas
  • Stasis (slowdown of the gastrointestinal tract)

Repeatedly ingesting clay litter or chemicals found in some litters may also lead to more serious long-term problems. Ongoing exposure can cause liver and kidney damage over time.

Plus, the high clay content of clay litters does not get digested or pass through a rabbit's system well. Large amounts of clay can lead to a buildup of dry stools in the digestive tract. This impaction can be painful and further reduce a rabbit's appetite.

For the safest litter choice, look for natural litters made from materials like recycled paper, citrus, or pine that will not harm your rabbit's sensitive digestion. Avoid any scented, clumping, or clay-based cat litters.

Cat Litter Types to Avoid

To recap, here are the specific kinds of cat litter that should be avoided for rabbit litter boxes:


Any clumping clay litter or clumping crystal litter is unsafe for rabbits. Examples include:

  • Clumping clay litters like Tidy Cats and Clovers
  • Clumping crystal litters like Precious Cat and Dr. Elsey's
  • Swheat Scoop – this is a clumping wheat litter

The clumping agents used in these litters can cause lethal intestinal blockages if ingested by rabbits. Stick to a non-clumping litter instead.


Standard clay litters, even non-clumping kinds, are also not ideal for rabbits. Here are some reasons to avoid plain clay litter:

  • Contains fine dust that can irritate respiratory systems
  • May include added scents, chemicals, or deodorizers
  • Does not breakdown well if ingested; may cause impaction
  • Typically lacks adequate absorbency for urine

Look for a natural fiber, paper, or wood based litter instead of plain clay options.


Crystal litters like Silica gel beads should also be avoided. While non-clumping varieties will not cause blockages, they can still present problems:

  • Creates fine dust that irritates airways
  • Often perfumed or scented
  • Crystals may be ingested and cause intestinal discomfort
  • Rather expensive for litter box use

Rabbits should not be kept on crystal litters long-term. Consider a recycled paper or wood pulp litter instead.

Rabbit-Safe Litter

When choosing a suitable litter for rabbits, look for these qualities:


The litter must be non-toxic and safe if ingested. Avoid litters with any clumping agents, gelling ingredients, or chemicals. The litter should not contain any scents or deodorizers, as rabbits have sensitive respiratory systems and digestion.

High Absorbency

Rabbit urine is very concentrated, so litter needs to be highly absorbent. Look for litters made from paper pulp, aspen shavings, or grass hay to handle large urine volumes. Avoid clay options.


Litters with added fragrance oils, artificial scents, or chemicals should be avoided. Rabbits ingest some of their litter while eating and grooming. The litter must be 100% chemical-free and non-toxic.

Here are some top choices for safe, rabbit-friendly litters:

  • Paper pulp litter – brands like Carefresh and Yesterday's News
  • Recycled newspaper pellets -oload, stat right, etc
  • Aspen wood shavings – odor absorbing and soft wood
  • Citrus litter – made from orange or lemon peels

Always check the litter ingredients before buying. Avoid any that contain clumping agents, heavy perfumes, or chemicals not safe for consumption. With the right litter, you can keep your bunny both comfortable and healthy.

Safe Rabbit Litter Alternatives

While paper and wood-based litters are ideal for rabbits, they may not be readily available in some areas. In that case, you can explore some safe DIY alternatives using materials you likely already have around the house. Here are a few options:


Shredded paper makes an affordable litter substitution, provided the paper is chemical-free. Avoid glossy printed paper, as the inks could be harmful. Plain shredded newspaper, computer paper, or paper towel works well.

Replace the paper litter frequently, at least twice per week, as it will become saturated with urine quickly. Do not use clumping cat litter with newspaper thinking it will form safe clumps – ingesting the gelling agents is still extremely dangerous.

Natural wood fibers

Untreated wood shavings or chips from soft woods like aspen or pine make suitable litter materials. Cedar and oak wood should be avoided, as they contain volatile oils that can irritate a rabbit's system.

Look for organic horse bedding products made with pine or aspen. Line the box with a layer of wood chips or shavings for absorbency and odor control. Spot clean frequently and replace entirely each week.

Litter Alternatives

In a pinch, some other biodegradable materials can work:

  • Pine pellet horse bedding
  • Shredded cardboard
  • Organic hay or straw
  • Dry grass clippings
  • Leaf litter or shredded fall leaves

Avoid using materials like corn cob bedding, walnut shell litter, or clay options. While temporary substitutions are fine, try to transition to a paper or wood pulp litter as soon as possible for your rabbit's health and comfort.

Litter Box Setup

When introducing your rabbit to a new litter box, follow these tips for easy transition:

Add the Hay

Start by adding a generous pile of your rabbit's usual hay into the litter box. This helps establish the box as a feeding area right away.

Separate Hay to One Side

Pile the hay to one side or corner of the litter box. Then add litter material to the rest of the box. This allows space for both eating and using the litter.

Add the Litter

Pour an inch or two of rabbit-safe litter into the box. Paper pulp and wood pellets are absorbent, affordable options. Avoid clay, clumping, or scented litters.

Let your rabbit explore

Allow your rabbit to investigate and get used to the new litter box. Properly introducing it helps prevents accidents later on. Be sure to clean it regularly to establish good habits.

Swapping Out Rabbit Litter

For optimal odor control and hygiene, rabbit litter should be scooped daily and fully replaced weekly. Here are some tips for litter box upkeep:

  • Spot clean wet clumps and droppings daily
  • Every 2-3 days, dump everything out and wash the box
  • Disinfect with white vinegar or diluted hydrogen peroxide
  • Completely change out soiled litter weekly
  • Add fresh hay in small amounts daily or every other day

Provide one litter box per rabbit, plus an extra. Place boxes in corners Rabbits tend to use the bathroom where they eat and sleep. Proper litter habits go a long way in keeping rabbits healthy and your home clean!

With the right litter material and vigilant cleaning, you can successfully use a cat litter box for your bunny. Avoid clay clumping litters, crystals, and scented options. Choose a paper, pine, or aspen litter instead for safety. With a clean box and fresh litter, your rabbit can enjoy pellets freely without the hazards of cat litter.
