Can You Use Cat Litter for Rabbits?

Using cat litter for rabbits is generally not recommended. While cat litter may seem like an easy solution for rabbit owners, most types of cat litter contain ingredients that can be harmful to rabbits. Rabbits have very sensitive respiratory systems and intestines, so using the wrong litter can lead to potentially serious health issues.

The key concerns with using regular cat litter for rabbits are the risk of intestinal blockages, respiratory issues, and digestive problems. Clumping clay litters in particular are especially dangerous for rabbits. The clumping agents used in these litters can expand when ingested, causing blockages in the intestines. Additionally, the dust from clay litters can irritate a rabbit's respiratory tract.

While some rabbit owners may take the risk of using certain cat litters if they cannot find or afford rabbit-specific litter, it is always best to avoid regular cat litter. There are much safer, rabbit-friendly options available that will not put your rabbit's health at risk.

Intestinal Blockages

One of the biggest risks of using clumping clay cat litter for rabbits is that it can cause intestinal blockages, which can be life-threatening. When a rabbit ingests clumping clay litter, either by accidentally eating some while grooming themselves or intentionally eating it, the clumping agent called bentonite will expand inside the intestines. This expansion can lead to a dangerous blockage.

Signs that your rabbit may have an intestinal blockage include loss of appetite, lethargy, bloating, and abnormal stools. Rabbits are unable to vomit, so any blockage will require immediate veterinary attention. The blockage will need to be surgically removed by a vet before it ruptures the intestines.

Any cat litter containing clumping clay should always be avoided for rabbits. Even if you think your rabbit does not eat its litter, it is not worth the risk of a blockage occurring. There are much safer, non-clumping litters designed specifically for rabbits.

Respiratory Issues

Another health concern for rabbits using cat litter is respiratory irritation. Clay litters, even non-clumping kinds, contain dust that can be harmful if inhaled by rabbits. Rabbits have very sensitive respiratory systems and can easily develop respiratory infections when exposed to irritants.

The dust particles from clay cat litter can cause upper respiratory inflammation. Your rabbit may develop nasal discharge, sneezing, wheezing, and labored breathing. In some cases, the respiratory irritation can progress to pneumonia.

Seeking prompt veterinary care is important if your rabbit shows any signs of respiratory distress after being exposed to dust from cat litter. To avoid respiratory problems altogether, use dust-free litter made from paper, wood, or other organic materials.

Digestive Problems

Some ingredients used in cat litter to control odors and absorb moisture can also cause digestive upset in rabbits. Litters containing perfumes, deodorants, and antimicrobials may irritate the sensitive digestive tract of rabbits.

Diarrhea is one common symptom of digestive issues from inappropriate cat litter. The ingredients may alter the pH balance in the intestines or kill off beneficial gut bacteria. Your rabbit may also develop loss of appetite, lethargy, or bloating.

Rabbits require litter that is free of additives, perfumes, and chemicals. Simple, unscented litters made from paper or wood shavings are gentlest on a rabbit's digestive system. Monitor your rabbit's droppings closely when trying a new litter to watch for any diarrhea or changes.

Cat Litter Types to Avoid

When looking for litter for your rabbit, there are certain types of cat litter you will want to avoid:


As mentioned previously, clumping clay cat litter can cause life-threatening gastrointestinal blockages in rabbits. The clumping agents, usually bentonite clay, expand when moistened and can obstruct the intestines if ingested. Even if the packaging says it is safe for rabbits, it is best not to take the risk.


Non-clumping clay litters are less hazardous than clumping kinds but can still irritate a rabbit's respiratory tract. The clay dust poses a risk for respiratory inflammation and infection. The clay may also contain additives unsuitable for sensitive rabbit digestion.


Crystal cat litters contain silica gel crystals. While considered less dusty than clay, they can still pose a risk for intestinal obstruction if enough crystals are ingested. The crystals may also irritate the digestive tract.

Rabbit-Safe Litter

The safest cat litter alternatives for rabbits are litters made from natural, organic materials free of harmful chemicals and additives. Here are some things to look for:


Natural, toxin-free litters made from materials like recycled paper, wood shavings, or plant fibers are ideal choices. They contain no clumping agents, perfumes, or deodorants.

High Absorbency

Look for a litter with excellent moisture wicking ability to help control odors and prevent the growth of bacteria. Paper pellet litters in particular are very absorbent.


Avoid litters listing any chemical additives or scents. Rabbits have sensitive respiratory and digestive systems, so natural plant or wood-based litters are best.

Safe Rabbit Litter Alternatives

Here are some popular types of cat litter alternatives that are safe for rabbits:


Paper litter is highly absorbent and soft on rabbit feet. Recycled newspaper pellets and other paper-based litters make an excellent chemical-free choice.

Natural wood fibers

Litters made from kiln-dried aspen or pine shavings are safe options that allow for natural burrowing behavior. Ensure there is no cedar, which can be toxic.

Litter Alternatives

Some owners use rabbit-safe bedding materials like orchard grass hay as litter. The hay allows the rabbit to eat and eliminate in one place.

Litter Box Setup

To make your rabbit litter box appealing and easily accessible, follow these tips:

Add The Hay

Place a pile of fresh hay in one corner of the box. Rabbits like to nibble while they eliminate.

Separate Hay To One Side

Keep the hay separate from the litter area to help keep the hay clean and minimize waste.

Add The Litter

Pour your rabbit-safe litter into the box, avoiding the hay corner. Use about 1-2 inches of litter.

Swapping Out Rabbit Litter

Spot clean soiled litter daily by scooping out clumps of urine-soaked litter. To fully clean the box:

  • Empty out all used litter weekly or every other week

  • Wash the box with soap and water, rinse thoroughly

  • Allow box to dry completely before refilling with fresh litter

  • Replace hay as needed, at least weekly

Following this schedule will help control odors and waste. Make sure your rabbit always has access to a clean, hygienic litter box.
