Whether you’re a new bunny parent or a seasoned owner, you’ll discover fascinating insights into how to interpret your rabbit’s poop for optimal health.

What Does Rabbit Poop Look Like?

Rabbit poop is typically small, pellet-like, and firm. A normal, healthy rabbit will produce hundreds of round, dry, uniformly-textured fecal pellets each day. These pellets are usually relatively odorless and should be somewhat solid overall.

A rabbit's digestive system functions a bit differently than many other animals, which results in the formation of two different types of feces. The first type consists of the familiar dry, round pellets that most owners are accustomed to cleaning up on a daily basis. However, rabbits also produce a second type of feces called cecotropes, which they consume directly from their anus for additional nutritional intake. Cecotropes are soft, grape-like clusters coated in mucus that are reingested by the rabbit. They may sometimes be visible in the litter box if the rabbit's diet is unbalanced.

Overall, normal rabbit poop should be firm and dry, with a consistent shape and texture. Dramatic changes in the feces can signify an underlying health issue that requires veterinary attention. Monitoring your rabbit's poop daily provides important insight into their digestive health.

Normal Rabbit Poop Color

The normal color of healthy rabbit poop is brown. The exact shade can range from light brown to dark brown. This brown color is the result of bilirubin, a pigment created by the breakdown of red blood cells in the liver.

As the poop moves through the intestinal tract, bilirubin is concentrated and expelled in the feces. The specific brown shade depends on the concentration of the pigment. Lighter brown indicates lower levels of bilirubin, while very dark or even blackish poop has higher concentrations.

In general, normal rabbit poop should not be pale yellow, gray, green, or white in color. Dramatic deviations from the usual brown hue can signal health problems such as liver issues, intestinal blockage, infection, parasites, or dietary deficiencies.

It is also normal to see slightly darker or softer cecotropes that are reingested by the rabbit. These night feces serve an important nutritional purpose and their color results from the higher content of nutrients, vitamins, proteins and fats that are extracted from the harsh plant fibers rabbits commonly eat.

Normal Rabbit Poop Smells

Fresh normal rabbit poop has very little odor. The fecal pellets are made up of relatively dry, compacted waste products so they do not emit a strong smell. In fact, well-formed rabbit poop is typically rather odorless.

Sometimes an extremely faint earthy or grassy aroma can be detected if you place your nose close to fresh pellets. But in general, the poop should not have an offensive or strong odor of any kind if the rabbit is healthy.

While cecotropes may smell slightly more pungent due to their higher moisture content and different nutritional composition, they should not give off an extremely foul odor.

On the other hand, excessively stinky poop could indicate an imbalance in the rabbit's digestive system. Diarrhea or poop that is very wet or mushy is more likely to have an offensive smell. Foul-smelling poop that persists can signal issues like an intestinal blockage, parasite infestation, or bacterial overgrowth.

Normal Rabbit Poop Size

In adult rabbits, normal poop is roughly the size of a grape or raisin, though some variation exists among different breeds and individual animals. On average, healthy fecal pellets are 0.5-1 cm (0.2-0.4 inches) in diameter.

Young kits under 3 months old may initially have smaller poops, closer to 0.3 cm diameter. But their poop size should increase as they grow. Giant rabbit breeds can have slightly larger poop while dwarf breeds produce more petite pellets.

Regardless of breed, the poop should be rounded and uniform in size and shape. Drastic changes in stool size for a particular rabbit can indicate gastrointestinal issues. Significantly smaller poops may point to an obstruction that is preventing the colon from forming stools properly.

Meanwhile, excessively large or oddly shaped poop could mean the intestine is moving too slowly, allowing feces to accumulate into clumps or lose its regular form. Monitoring poop size helps spot potential problems early.

Abnormal Rabbit Poop

While normal rabbit poop is brown, round, and firm, abnormal feces can display changes in color, shape, texture, odor, or other qualities. Unusual poop is often the first noticeable sign of an underlying health issue requiring veterinary care.

Some common types of abnormal rabbit poop include:

  • Smaller/larger than normal
  • Softer/mushy consistency
  • Lack of fecal pellets
  • Irregular shape
  • Strange color
  • Excessive cecotropes
  • Diarrhea
  • Constipation/lack of poop
  • Presence of blood, mucus, or undigested food

Diarrhea and soft cecotropes are the most frequently seen kinds of abnormal poop. But any deviation from a rabbit's usual stool habits warrants attention. Catching problems early leads to the best treatment results.

Rabbit Poop Smaller Than Usual

One common type of abnormal rabbit poop is stools that are significantly smaller than what is normal for the individual rabbit. The fecal pellets may be less than half the typical size or even smaller.

Possible causes for abnormally small poop include:

  • Intestinal blockage – This obstruction prevents the colon from forming stools properly.

  • Dehydration – Lack of fluid leads to concentrated, compacted poop.

  • Diet change – Lower fiber or indigestible foods can result in small poops.

  • Pain during defecation – The rabbit strains less due to discomfort.

  • Muscle weakness – Intestinal muscles lack strength to fully eliminate waste.

  • Partial intestinal stasis – Peristalsis slows, limiting fecal output.

  • Stress – Scary events or environmental changes may suppress defecation.

  • Dental problems – Chewing issues make food digestion incomplete.

Rabbits with persistently tiny poops need veterinary assessment to pinpoint the underlying cause and proper treatment. Providing wet leafy greens, exercise, hydration, and stress reduction can help in mild cases.

Rabbit Poop Clumped Together

While single, dry, round pellets are ideal, rabbit poop that clumps together is abnormal. The stool may form larger clustered masses rather than separating into individual pellets.

Possible reasons for clumped poop include:

  • Dehydration – Lack of fluid results in poop that sticks together.

  • Muscle weakness – Intestines can't propel stool normally to segment it.

  • Partial intestinal stasis – Slowed movement causes feces to amalgamate.

  • Diet issues – Too little fiber or excess starch and sugars lead to clumping.

  • Pain – Discomfort when defecating means the rabbit can't fully empty colon.

  • Hot weather – Rabbits produce less stool and are prone to dehydration.

  • Litter box issues – Wet, soiled litter causes poop to stick together.

  • Lack of exercise – Sedentary rabbits are more prone to partial stasis.

Mild clumping may resolve with hydration, diet adjustments, sanitary litter habits, exercise, and pain relief. But significant or ongoing clumped poop warrants an exam to check for underlying issues.

Rabbit Poop Lighter Than Normal

While healthy rabbit poop is typically brown in color, abnormal lighter stool can range from soft yellow to pale gray, sometimes with a greenish tint. Light poop generally signals an issue with the liver, small intestine, cecum, or diet.

Possible causes include:

  • Liver disease – Reduced bilirubin production leads to less brown pigment.

  • Bile duct issues – Bile can't reach the intestines to color the poop.

  • Small intestinal disease – Nutrient absorption issues lead to pale poop.

  • Excess cecotrope production – Overwhelms the liver's bilirubin capabilities.

  • Diet lacking pigments – Alfalfa, greens, and some veggies provide poop color.

  • Rapid GI transit time – Food passes so quickly that bilirubin can't be concentrated.

  • Coccidia parasites – Damage gut lining and impair bile processing.

  • Stress – Can inhibit bile flow and gut motility.

Supportive care with hydration, probiotics, and nutrients may help mild cases. But significant liver or intestinal disease requires diagnosis and specific treatment. Light poop lasting over 12 hours warrants a veterinary visit.

True Diarrhea In Rabbits

Diarrhea is one of the most common types of abnormal rabbit poop. True diarrhea in rabbits is defined as fecal pellets that are unformed, watery, and resemble a splatter rather than solid poops. The rabbit may also have little to no control when passing the diarrheal stool.

Possible causes of true diarrhea include:

  • Bacterial infection – E. coli, Clostridium, and Salmonella can cause enteritis.

  • Parasites – Coccidia and sometimes tapeworms irritate the intestines.

  • Antibiotics – Disrupt gut flora, allowing harmful bacteria to proliferate.

  • Toxins – Ingestion of poisonous plants, chemicals, or medications.

  • Stress – Flood of stress hormones can accelerate GI motility.

  • Diet issues – Too much sugar, starch, or protein irritates the intestines.

  • Internal disease – Liver or endocrine disease may contribute to diarrhea.

Mild cases may resolve with rest, gentle hydration, and probiotics. But diarrhea lasting more than 24 hours requires veterinary assessment and may need antibiotics, antidiarrheals, or IV fluids.

Rabbit Poop Strung Together

Though not true diarrhea, abnormal rabbit poop that appears strung together in clusters or clumps also warrants attention. This stool often has a toothpaste-like texture and may leave a trail of slime across the coat or floor.

Possible causes include:

  • Diet too high in carbohydrates – Excess sugars and starches irritate intestines.

  • Partial intestinal stasis – Slowed motility results in mushy poop.

  • Intestinal dysbiosis – Unhealthy gut flora leads to improperly formed stool.

  • Stress – Alters intestinal motility and gut flora populations.

  • Dehydration – Lack of fluid leaves poop dry and sticky.

  • Temperature extremes – Heat or cold impairs gut function.

  • Dental issues – Difficulty chewing means poorly digested ingesta.

Providing hydration, gut-healthy foods, probiotics, and stress reduction may help. But recurrent abnormal poop requires an exam to identify contributing factors.

Mucus in Rabbit Poop

Small amounts of mucus coating healthy cecotropes is normal as it helps the rabbit reingest them. But excessive mucus or slime mixed throughout the fecal pellets is abnormal and indicates irritation of the intestines.

Possible causes of mucus in rabbit poop include:

  • Parasite infection – Worms or coccidia irritate the gut lining.

  • Bacterial enteritis – Harmful bacteria proliferate and damage the intestines.

  • Stress – Flood of hormones increases intestinal mucus production.

  • Diet changes – Excess carbs, sugars, protein or fats can inflame the gut.

  • Dehydration – Causes mucus to appear more noticeable.

  • Medication side effects – Some drugs increase mucus secretion.

  • Cancer – Lymphoma or adenocarcinoma may produce excess mucus.

  • Foreign body – Ingested object obstructs intestines, causing inflammation.

Severe or recurring cases should receive veterinary assessment. Treatment depends on the underlying cause but may include antibiotics, anthelmintics, IV fluids, or medications to reduce intestinal inflammation.

Dry Crumbly Rabbit Poop

Dry, crumbly poop that lacks the normally compact, cohesive pellet shape may indicate dehydration or other issues. The stool appears almost like sawdust or dry crumbs rather than solid individual pellets.

Several factors can cause dry, crumbling poop:

  • Dehydration – Lack of fluid leaves poop hard and dry.

  • Diet too low in fiber – Inadequate roughage makes stools fragile.

  • Obstruction – Blockages prevent normal poop formation.

  • Pain – Discomfort while defecating means rabbit can't empty colon fully.

  • Fur chewing – Swallowing too much hair dries out the poop.

  • Dental issues – Makes rabbits swallow more hair while eating.

  • Hot temperatures – Increase risk of dehydration.

  • Excess diuretics – Some medicines lead to fluid loss.

  • Kidney disease – Reduces the body's ability to conserve fluid.

Providing hydration, a high fiber diet, brushing and grooming can help restore more normal stools. But ongoing crumbly poop should be evaluated by a veterinarian.

Cecotropes In Rabbits

In additional to the familiar fecal pellets, rabbits normally produce a second type of stool called cecotropes. These are soft, grapelike clusters of food material that are reingested directly from the anus. Cecotropes play an important nutritional role for rabbits.

Cecotropes form in a part of the digestive tract called the cecum. The cecum contains fermenting bacteria that help rabbits digest the tough fiber in hay and grasses. These microbes extract many vitamins, proteins and other nutrients that would otherwise be excreted.

The rabbit's body recovers these nutrients by initially excreting them in a special type of stool – the cecotrope. The cecotrope is coated in mucus and especially soft and odorous to stimulate the rabbit to eat it. Reingesting cecotropes gives rabbits access to these reclaimed nutrients.

Cecotropes are secreted at a different time than normal poop, often during periods of rest. Rabbits consume them straight from the anus, leaving no trace in the environment. You may only witness cecotropes if your rabbit has an unbalanced diet causing excess production.

Cecal Dysbiosis

While cecotropes are normal, an imbalance in the cecal bacteria population can lead to health issues. This is known as cecal dysbiosis, which occurs when harmful bacteria overpopulate the cecum.

Signs of cecal dysbiosis include:

  • Excess cecotrope production – Too many soft stools are excreted.

  • Changes in cecotrope color/texture – May become mushy or lack the glistening mucus coat.

  • Uneaten cecotropes – Rabbit stops consuming them, leaving them in environment.

  • Loose cecotropes – Grape-like clusters lose their shape.

  • New onset diarrhea – Dysbiosis allows pathogens to proliferate.

  • Gas or gurgling intestines

  • General lethargy or gastrointestinal distress

Cecal dysbiosis makes it difficult for the rabbit to digest food properly. It is often triggered by diet imbalances, stress, antibiotics, or intestinal stasis. Providing probiotics and limiting sugary foods may help restore balance. Recurrent cases need medical treatment.

GI Stasis And Cecal Impaction In Rabbits

Gastrointestinal stasis refers to a dangerous slowing of the intestinal tract. It can be accompanied by a cecal impaction, which is a mass of accumulated material blocking the cecum.

When peristalsis slows, ingesta backs up behind the obstruction instead of passing normally through the colon. This allows material to build up and harden within the cecum pouch.

Signs of cecal impaction and GI stasis include:

  • Smaller, irregular poop

  • Lack of fecal pellets or no poop at all

  • Straining to pass stool with little output

  • Bloated or distended abdomen

  • Loss of appetite

  • Lethargy, lying in hunched position

  • Grinding teeth from intestinal pain

  • Crouched posture with feet gathered under body

Stasis and impaction can become fatal within 12-24 hours without veterinary treatment. Aggressive hydration, motility drugs, and laxatives are typically needed. Prevention through proper diet and hydration is key.

Signs of Impaction

A cecal impaction occurs when ingesta accumulates and hardens in the cecum rather than passing through the colon normally. Impaction is often related to "hairballs" from excessive grooming. Signs include:

  • Small, irregularly shaped poop

  • Lack of fecal pellets or no poop at all

  • Straining, grumbling intestines

  • Abdominal bloating, distension

  • Loss of appetite

  • Sitting hunched over in obvious discomfort

  • Reduced activity, lethargy

  • Teeth grinding indicating intestinal pain

  • Crouched posture with feet gathered under body

Rabbits suffering a cecal impaction are in obvious distress. They stop eating and become increasingly lethargic as toxins build up. Aggressive veterinary treatment is crucial to prevent GI stasis and death. Prevention through proper diet and avoiding excessive fur ingestion during grooming is key.
