Hedgehog Pooping or Peeing Blood: Causes and Next Steps

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-10-03

Blood in a hedgehog's poop or urine is never normal, and it usually points to a problem in the digestive tract, urinary tract, or reproductive tract. The most common serious causes in African pygmy hedgehogs are uterine tumors and other reproductive disease, urinary infection or stones, and gastrointestinal tumors. Because these conditions can worsen quickly, any hedgehog with visible blood should be seen by a veterinarian who treats exotic pets.

Quick Answer

• Blood in stool (hematochezia) or urine (hematuria) in a hedgehog is a sign of disease, not a minor irritation, and it needs a veterinary exam.
• In female hedgehogs, reproductive tract disease is a leading cause. In one report of 15 captive females with uterine lesions, all had vaginal bleeding and 11 of 13 had blood in the urine [1].
• Gastrointestinal cancer can cause bloody stool along with weight loss in this species [2].
• Some pink or red urine is not blood at all. A rare pigment disorder called porphyria can make urine look pink and glow under ultraviolet light [3].
• Do not wait to "see if it clears up." Call an exotic-animal vet the same day you notice blood, and go to an emergency clinic now if your hedgehog is weak, cold, or not eating.

What Blood in Hedgehog Stool or Urine Looks Like

Hedgehog waste is small, so blood can be easy to miss. Fresh blood in stool often looks like bright red streaks, drops, or a red-tinged coating on the droppings. Blood that has been in the gut longer may make stool look dark, tarry, or black.

Blood in urine can range from a faint pink tint to obvious red. It may appear on the bedding, on the hedgehog's belly or feet, or in the litter area. Because urine and stool often land in the same spot, owners sometimes cannot tell which one is bloody. That distinction matters, and your vet will help sort it out.

Normal hedgehog stool is small, dark, and fairly firm, and it varies with diet. Normal urine is pale yellow to slightly cloudy. Some hedgehogs produce naturally colored urine after eating certain foods, but true red or pink color should always be checked.

One important look-alike: a 6-month-old male hedgehog with pink urine turned out to have congenital erythropoietic porphyria, a pigment disorder. His urine had no blood cells or other abnormalities, only a pink color and fluorescence under ultraviolet light, and his teeth, feet, and spines also glowed [3]. This is rare, but it shows why a vet visit matters more than guessing from color alone.

Why Is My Hedgehog Pooping Blood? Main Causes

The causes below are grouped by body system. Many of them overlap in how they look, which is why testing is needed.

Reproductive Tract Disease (Most Common in Females)

In female African pygmy hedgehogs, the reproductive tract is a top source of blood. A study of 15 captive females aged 3 to 5 years found 28 proliferative uterine lesions, including adenosarcomas, endometrial stromal sarcomas, and endometrial polyps. Vaginal bleeding occurred in all cases, and blood in the urine occurred in 11 of 13 cases where it was recorded [1]. Ovariohysterectomy (spay surgery) allowed prolonged survival in that group [1].

Other reports describe the same pattern. A 3-year-old female with blood in the urine had a mammary adenocarcinoma and a granulosa cell tumor removed, and her urine cleared after surgery [4]. A 5-year-old female with blood in the urine had a uterine spindle cell tumor, an endometrial polyp, and other uterine disease, and the bleeding stopped after ovariohysterectomy [5]. Older females can also develop endometrial polyps that cause bloody vaginal discharge, which owners may mistake for bloody urine [6].

Urinary Tract Infection or Stones

A urinary tract infection (UTI) can cause blood in the urine, straining, frequent urination, and discomfort. In one hedgehog with blood in the urine, a vulvar culture grew heavy Enterococcus and Streptococcus bacteria that were susceptible to common antibiotics [5]. That said, infection is often secondary to another problem, such as a tumor or stone, so vets look for an underlying cause.

Gastrointestinal Disease and Cancer

Bloody stool in a hedgehog can come from the intestines. A 4-year-old hedgehog seen for weight loss and bloody stool was diagnosed with gastrointestinal lymphosarcoma, a cancer of the lymphatic system [2]. Blood in stool can also come from severe inflammation, parasites, or other intestinal disease. Any hedgehog with bloody stool plus weight loss needs prompt testing.

Other Causes

Severe anemia from blood loss is a real risk. One 1-year-old female with blood in the urine and poor appetite had a packed cell volume (a measure of red blood cells) of only 14%, and she needed a blood transfusion before and during surgery [7]. This shows how quickly blood loss can become life threatening.

If you want to compare how blood in waste is handled in other species, our guides on why a dog poops blood and blood in a dog's urine cover similar principles, though hedgehogs have their own specific risks.

Red Flags That Make It an Emergency

Go to an emergency veterinary clinic right away if your hedgehog has any of these signs:

• Pale or white gums or mucous membranes
• Weakness, wobbliness, or collapse
• Feeling cold to the touch
• Not eating or drinking for more than a few hours
• Heavy or continuous bleeding
• Labored breathing
• Seizures or unusual twitching

Severe anemia from blood loss can develop fast. In the reported case, the hedgehog's red blood cell measure dropped from 14% to 7% within 72 hours after transfusion [7]. A hedgehog that is weak or pale may not have time to wait for a regular appointment.

If your hedgehog is bright, eating, and passing only a small amount of blood, call your vet the same day and follow their instructions. Do not assume small amounts are harmless.

Safe Things You Can Do at Home While Waiting

You cannot treat this at home, but you can gather information that helps your vet and keeps your hedgehog comfortable.

• Save a sample. Place a small amount of bloody stool or urine-soaked bedding in a clean, sealed plastic bag or container and bring it to the visit.
• Take photos. Photograph the bedding, the droppings, and your hedgehog's belly or vent area in good light.
• Track the timeline. Note when you first saw blood, how often it appears, and whether it is in stool, urine, or both.
• Note other signs. Record appetite, water intake, weight, activity level, and any straining.
• Keep your hedgehog warm and quiet. Use a heat source set to a safe temperature and avoid handling more than needed.
• Do not give any medication. Never give human pain relievers, antibiotics, or dewormers. Many are toxic to hedgehogs, and the dose depends on weight and health. Your veterinarian will calculate any dose.
• Offer normal food and water. Do not fast your hedgehog unless your vet tells you to.

What the Veterinarian Will Check and Test

Your vet will start with a full history and physical exam, including palpation of the belly. In one reported case, a firm, immobile mass was felt in the rear abdomen near the uterus and bladder [7]. Your vet will also check your hedgehog's gums for color and hydration.

Expect some of these tests:

• Urinalysis. This checks for red blood cells, bacteria, crystals, and other abnormalities. It can also rule out pigment causes like porphyria, which showed no physical, chemical, or cellular abnormalities other than pink color and UV fluorescence [3].
• Fecal exam. This looks for parasites, blood, and other abnormalities in the stool.
• Blood work. A complete blood count and chemistry panel assess anemia, infection, and organ function. In the gastrointestinal lymphosarcoma case, blood work showed marked leukocytosis with lymphocytosis and atypical circulating lymphocytes [2].
• Imaging. Ultrasound or radiographs can find masses, stones, or fluid. Ultrasound in one case revealed an unidentifiable tubular structure in the reproductive tract area [5], and in another it raised suspicion for uterine pathology [7].
• Cultures. A sample from the vulva or urine may be cultured to identify bacteria and choose the right antibiotic. One culture grew Enterococcus and Streptococcus species susceptible to trimethoprim sulfa and enrofloxacin [5].
• Biopsy or surgery. If a mass is found, your vet may recommend exploratory surgery. Ovariohysterectomy both diagnoses and treats many uterine tumors, and it allowed prolonged survival in a group of affected hedgehogs [1].

Treatment depends on the cause. Options include antibiotics for infection, surgery for tumors or stones, supportive care such as fluids and warmth, and in severe anemia cases, a blood transfusion. One hedgehog received a transfusion of type A feline whole blood before and during surgery and recovered well from anesthesia [7]. Your vet will decide what is safe and appropriate for your pet.

Prevention and Monitoring

You cannot prevent every cause of blood in stool or urine, but you can catch problems early.

• Weigh your hedgehog weekly. Weight loss is a common early sign of serious disease, including uterine tumors and gastrointestinal cancer [2][1].
• Check bedding daily. Look for blood, straining, or changes in urine and stool color.
• Know your hedgehog's normal. Small changes in appetite, activity, or waste are easier to spot when you know the baseline.
• Spay female hedgehogs if your vet recommends it. Uterine tumors are common in older females, and ovariohysterectomy allows prolonged survival in affected hedgehogs [1].
• Keep regular wellness visits. Older hedgehogs, especially females 3 years and up, benefit from routine exams [1].
• Act fast on blood. Early treatment gives your hedgehog the best chance.

Limitations and When to Contact a Veterinarian

This article cannot tell you what is causing blood in your specific hedgehog. Only a veterinarian who examines your pet and runs tests can do that. Individual cases need a veterinarian.

Contact a veterinarian the same day if you see blood in stool or urine, even if your hedgehog seems fine otherwise. Go to an emergency clinic now if your hedgehog is weak, pale, cold, not eating, bleeding heavily, or having trouble breathing. Schedule a routine visit if you notice a pink urine color but your hedgehog is otherwise bright and eating normally, since pigment causes like porphyria are not emergencies [3] but still need a diagnosis.

Frequently Asked Questions

Can blood in hedgehog poop go away on its own?

It can stop temporarily, but the underlying cause usually remains. Bloody stool in a hedgehog has been linked to serious conditions such as gastrointestinal cancer [2]. Waiting risks letting the disease progress. See a vet instead of watching and hoping.

Is bloody urine more common in female hedgehogs?

Yes, reproductive tract disease is a major cause in females. In one group of 15 captive females with uterine lesions, all had vaginal bleeding and most had blood in the urine [1]. Males can still have urinary or intestinal problems, so any hedgehog with blood needs an exam.

Could my hedgehog's pink urine be something other than blood?

Yes. A rare pigment disorder called congenital erythropoietic porphyria can make urine pink and cause teeth, feet, and spines to glow under ultraviolet light, with no blood cells in the urine [3]. Only testing can tell the difference.

Will my hedgehog need surgery?

Not always. Some causes, such as urinary infection, are treated with antibiotics [5]. Others, such as uterine tumors, often require ovariohysterectomy, which allowed prolonged survival in affected hedgehogs [1]. Your vet will recommend based on the diagnosis.

How do I collect a urine or stool sample from my hedgehog?

Place clean plastic wrap or a small clean tray under your hedgehog during handling, or collect soiled bedding right after your pet goes. Seal the sample in a clean container and bring it to the visit. Fresh samples give the best results, so collect as close to the appointment as you can.
