Bloody Poop in Cats: Causes Symptoms and Treatment

Identifying Bloody Poop in Cats

As pet owners, we all want the best for our furry companions. One of the most important ways we can do this is by monitoring their stool for any changes, including the appearance of blood.

Identifying bloody poop in cats is crucial in helping to maintain their health and preventing potential health problems. In this article, we will discuss the appearance of blood in cat poop, the importance of monitoring your cat’s stool, and what to do in emergency and non-emergency situations.

Appearance of Blood in Cat Poop

The appearance of blood in cat poop can vary. It can be bright red, black, or even watery.

Blood clots and mucus may also be present. Each type of appearance can indicate different conditions, which is why it is important to take note of these changes.

Black poop: If the stool is black, it may indicate an upper gastrointestinal tract bleeding, such as from the stomach or small intestine. This type of bleeding can be a result of several things, including a stomach ulcer, ingestion of toxins or foreign objects, or cancer.

Bright red blood: Bright red blood is often indicative of lower gastrointestinal tract bleeding, such as from the colon or rectum. This type of bleeding may be caused by several things, including inflammation of the colon, tumors, parasites, or an injury to the rectal area.

Blood clots: The presence of blood clots in your cat’s stool may indicate a more severe condition, such as a clotting disorder or cancer. Blood and mucus: The existence of bloody mucus in your cat’s stool may be due to intestinal inflammation such as inflammatory bowel disease or a bacterial infection.

Watery blood: Watery blood can indicate colitis or other conditions that affect the colon. This type of stool may also contain mucus or other foreign materials.

Importance of Monitoring Cat’s Stool

The consistency and appearance of your cat’s stool can be the first sign of health problems. Therefore, it is essential to monitor any changes in their stool.

Pet owners can easily monitor this by keeping an eye on their cat’s litter box. The frequency, amount, and consistency of stool can change with diet, medication, or underlying health concerns.

Cat’s health: Changes in your cat’s stool could indicate health problems such as anemia, infections, or inflammatory bowel disease. Change in diet: If you’ve recently changed your cat’s diet, their stool may change as well.

Switching your cat’s food too quickly can cause diarrhea or constipation, which can lead to bleeding. Consistency: The consistency of your cat’s stool can also indicate health problems.

Loose stools, diarrhea, or constipation can be signs of health issues such as parasites and specific infections. Severity of Blood in a Cat’s Stool

If you notice blood in your cat’s stool, the severity of the situation can vary.

Some cases require immediate medical attention, while others may need monitoring to see if symptoms persist.

Determining Emergency Situations

If you notice any of the following signs of your cat, seek emergency veterinary care as soon as possible:

Amount of blood: If you notice a large amount of blood in your cat’s stool, it is critical to seek emergency care immediately. A lot of blood can quickly lead to severe anemia and shock.

Pale/blue/deep red gums: Paleness or blue colorization of the gums in your cat may result from internal bleeding. In contrast, a deep red color can indicate dehydration and inflammation.

Repeated vomiting: This symptom, along with blood in the stool, can indicate a blockage in the intestine, which can cause dehydration, shock, or death. Severe diarrhea: Diarrhea that persists for over a day can cause severe dehydration and electrolyte imbalance.

Pain, weakness, lack of energy: Severe pain can also cause a loss of appetite, lethargy, and excessive sleeping, which can result from many underlying health problems. Underlying health problem: Finally, if your cat has a pre-existing health problem, blood in the stool can make the condition worse.

Non-Emergency Situations

If the amount of blood in your cat’s stool is minimal and there are no other signs of illness, it still warrants scheduling a visit with the veterinarian. Your pet may have a mild infection or be constipated, which can be treated with medication or topical ointments.

Cat owners should note, however, that blood in cat poop should never be ignored, as it can be a sign of an underlying health problem.


In conclusion, identifying bloody poop in cats is essential in maintaining your pet’s health and preventing future health complications. Pet owners should monitor the consistency and appearance of their cat’s stool regularly.

When blood is present, it is vital to note the type of blood and any other accompanying symptoms and seek immediate veterinary care if you observe any emergency signs. By taking these precautions, cat owners can identify issues early on and prevent them from turning into more severe conditions.

Causes of Bloody Poop in Cats

Cats are known for their fastidious nature and are meticulous in their habits. However, when it comes to their litter boxes and poop, it’s not always rainbows and unicorns.

One of the most crucial things pet owners must keep an eye out for is bloody poop in cats. There are many potential reasons for this, ranging from medical conditions to environmental factors.

In this article, we will explore the common causes of bloody poop in cats and what pet owners can do to help their furry companions.

Medical Conditions

There are several different medical conditions that can cause bloody poop in cats. The most common conditions that veterinarians see include:

Diarrhea and Constipation: Both diarrhea and constipation can cause irritation in the colon, rectum, and anus, which can cause bleeding.

Diarrhea can also be a symptom of more severe conditions such as inflammation in the colon. Intestinal Parasites: Intestinal parasites such as hookworms and roundworms can cause bleeding in the stool.

They can also damage the intestinal walls, leading to long-term health problems. Organ Dysfunction: Failure of critical organs such as the liver or kidneys can make it hard for the cat to regulate its body functions properly.

This can lead to bloody stools as these organs are responsible for filtering waste from the bloodstream. Inflammatory Bowel Disease: Inflammatory bowel disease (IBD) is a condition where the cat’s immune system attacks its intestine, causing inflammation and bleeding.

This condition can be difficult to diagnose, but with proper treatment, it can be managed. Bacterial/Viral/Fungal Infections: These types of infections are relatively common in cats, and the symptoms can range from minor upset stomach to severe illness.

When the infection reaches the digestive tract, it can cause bloody stools. Cancer and Growths: Although it is relatively rare, cancer and growths in the digestive tract can cause bloody stools.

In some cases, growths can cause a blockage in the digestive tract, making it difficult for the cat to pass stools.

Environmental Factors

Several environmental factors may cause bloody poop in cats, including:

Foreign Bodies: Foreign bodies like hair, plastic, or bones, can cause irritation, inflammation, and bleeding. These foreign objects can cause blockages in the intestine leading to signs of vomiting and abdominal pain.

Toxins: Certain household items such as cleaning products, pest control products, and even human food may contain harmful toxins that can cause severe illnesses in cats and bloody stools. Drugs: Certain medications can cause gastrointestinal problems in animals, mainly if you fail to correctly dose them.

These medications can cause mild to severe side effects and eventually lead to bloody stools. Stress: Cats can become stressed due to many factors, such as new environments, being surrounded by unfamiliar people, and even loud noises.

When a cat becomes stressed, it can cause digestive and bowel problems, leading to bloody stools. Adverse Food Reactions: Some cats may have allergies or intolerances to certain foods, which can cause dry and itchy skin and gastrointestinal issues.

The inflammation caused by the adverse food reaction can eventually cause bloody stools. Trauma: Accidental injury to the abdomen or pelvis can cause internal bleeding and eventual blood in the stool.

Diagnosis and Testing

If you notice blood in your cat’s stool, you should take them to the veterinarian as soon as possible. The veterinarian will conduct an examination and test to identify the cause of the bloody stools.

The following are typical steps taken:

Initial Questions and Examinations

During your cat’s initial visit to the vet, the vet will ask you questions about your cat’s health history, dietary practices, previous health problems, and other related details. The vet will also do a physical examination, including assessing the cat’s heart rate, temperature, and weight.

Based on the results, the veterinarian will determine if they need to conduct any additional diagnostic tests.

Additional Diagnostic Testing

Fecal Examination: A fecal examination can detect the presence of parasites and other microorganisms present in the cat’s digestive tract and stool. Complete Blood Cell Count: This test measures the number of white and red blood cells in a blood sample.

This helps the vet identify if there are any underlying infections, inflammations, or anemia. Blood Chemistry Panel: A blood chemistry panel measures the levels of various chemicals and enzymes in the bloodstream.

This can detect any changes that might occur due to diseases such as kidney or liver failure. Urinalysis: This test looks at a urine sample and can identify any bladder or kidney problems.

Specialized Laboratory Tests: More specific tests, such as testing for feline leukemia virus, can be carried out by specialized laboratories to rule out any severe viral infections. X-ray: An x-ray can check for abnormalities in the abdominal area that may be causing internal bleeding.

Ultrasound Exam: An ultrasound can give a better look at the internal organs, including any masses or growths. Endoscopy: Endoscopy involves looking inside the digestive tract using a small camera on a flexible tube.

Surgery: In some cases, exploratory surgery may be needed to check for any internal injuries or blockages. Tissue Biopsies: A tissue biopsy helps to accurately identify any tumors, growths, or masses in the digestive tract.


Bloody poop in cats is a common symptom of underlying health problems. The causes of bloody diarrhea or stool in cats vary from environmental factors to underlying medical conditions.

Therefore, it is crucial to monitor your pet’s health and consult a veterinarian if there are any changes in their bowel movements. With timely and appropriate medical attention, pets can enjoy happy and healthy lives with their owners.

Treatment for Cats with Blood in their Stool

Cats that have blood in their stool require immediate attention from their veterinarian. After diagnosis, treatment typically involves stabilizing the cat’s condition, treating underlying medical conditions, and making dietary adjustments.

In this article, we will explore various treatment options for cats with bloody stools. Stabilizing the Cat’s Condition

For cats with severe blood loss or dehydration, the veterinarian may focus on stabilizing the cat first.

This includes administering fluids intravenously and possibly giving a blood transfusion. Dehydration can occur when the cat is suffering from severe diarrhea or is unable to consume food and water regularly.

Treatment for Underlying Health Problems

Once the cat has been stabilized, treatment for the underlying cause of the bloody stool can begin. The treatment may vary based on the cause and type of underlying condition.

Some common treatments include:

Medications for Intestinal Parasites/Bacterial Infections/Stool Softening: Medications can help treat underlying infections, intestinal parasites, or stool softening to reduce the chances of the cat getting constipated. Antibiotics can help treat bacterial infections in the digestive tract.

Stool softeners, on the other hand, can help reduce pain and straining while defecating, making it easy to pass stool without causing further irritation to the colon. Surgery/Endoscopy for Bleeding/Foreign Bodies/Tumors: In some cases, the veterinarian may recommend surgery or endoscopy to remove tumors or foreign bodies that may be causing the bloody stool.

Symptomatic Treatment for Severe Diarrhea: Severe diarrhea can cause dehydration and inflammation, which can lead to bloody stools. The vet may recommend medications to manage symptoms such as anti-inflammatory, pain relief, and anti-diarrhea medication.

Dietary Recommendations

Diet plays a significant role in treating cats with bloody stools. Depending on the underlying cause of the bloody stool, the veterinarian may recommend a change in diet, such as:

High-Fiber Foods: For constipation and intestinal inflammation, high-fiber foods that are easy to digest and rich in moisture can provide relief.

These include wet cat food, pumpkin, and fiber supplements. Low-Fiber Foods: For cats with diarrhea, lower fiber content helps reduce the frequency of bowel movements and supports overall gut health.

An excellent example of low-fiber foods is boiled rice mixed with a small amount of boiled chicken breast. Hypoallergenic Foods: In some cases, a cat’s sensitivity to certain types of protein or grains can cause blood in their stool.

Hypoallergenic food, or diets that are free of by-products or animal proteins, can help reduce inflammation in the digestive tract. These diets typically contain novel protein and carbohydrate sources like venison, rabbit, or duck.

Probiotics: Probiotics are bacteria or yeast supplements that contribute to a better gut environment. They can also help improve digestion, reduce inflammation, and boost the immune system.

Probiotics can be in tablet form or added to the cat’s food.


Treating a cat with blood in their stool requires close attention from the cat’s owners and their veterinarian. With proper stabilization and treatment for the underlying medical condition, the cat can recover quickly and live a healthy and active life.

In addition, making dietary changes that promote digestive health can help reduce the chance of developing complications in the future. Therefore, it is crucial to seek veterinary attention promptly and to provide the appropriate treatments to help your cat make a full recovery.

In conclusion, blood in a cat’s stool can result from various medical conditions and environmental factors. The appearance of blood in a cat’s stool is a critical indication of an underlying health concern that pet owners should never overlook.

By monitoring the frequency, consistency, and appearance of your cat’s stool, it is easier to identify any changes promptly. Immediate veterinary attention is necessary to diagnose and treat the cause of the bleeding.

Treatment may include stabilizing your cat’s condition, treating underlying illnesses, and adjusting their diet. With proper medical attention, dietary adjustments, and close monitoring, the chances of a full recovery and future complications can significantly improve.

Therefore, pet owners should work closely with their veterinarian and remain vigilant in monitoring their cat’s health.
