There are various reasons why your cat might have blood in their poop. Some reasons may be relatively harmless, while others require urgent medical attention. In this blog post, we will delve into the possible causes of bloody stool in cats and what you can do to help them.

Firstly, we’ll explore some common causes such as gastrointestinal infections, parasites, and food intolerance. But we won’t stop there – we’ll also look at more severe conditions like inflammatory bowel disease, cancerous growths, and foreign objects.

It is crucial to monitor your cat’s symptoms closely and seek veterinary help as soon as possible if you notice any concerning changes in their behavior or health. Remember that early detection of any illness can lead to better outcomes for your feline friend.

So if you’re wondering why your cat has blood in their poop, don’t fret. This blog post will provide you with valuable information about this troubling issue and what steps you can take to ensure your furry companion stays healthy and happy.

Common Causes of Blood in Cat Poop

Understanding the common causes of this issue can help you identify the underlying problem and seek appropriate treatment for your cat.

Dietary changes are the most common cause of blood in cat poop. Sudden changes in your cat’s diet can lead to digestive issues and potentially cause blood in their stool. Additionally, if your cat has ingested something they shouldn’t have, like a foreign object or toxic substance, this can also lead to blood in their poop.

Inflammatory bowel disease (IBD) is another potential cause of blood in cat poop. IBD is a chronic condition that affects the digestive tract and can cause inflammation, ulcers, and other issues. This condition can be difficult to diagnose and may require a visit to the veterinarian for further testing.

Parasites, such as worms and protozoans, are another common cause of blood in cat poop. These parasites can damage the lining of the intestine, leading to bleeding. It’s important to regularly deworm your cat and keep them up to date on preventative medications to avoid this issue.

Lastly, stress can contribute to blood in cat poop. Cats are sensitive creatures, and changes in their environment or routine can cause stress-induced digestive issues. If you notice any changes in your cat’s behavior or routine, try to minimize any potential sources of stress.


One issue that can cause concern is constipation, which occurs when your cat has difficulty passing stools. It can even lead to blood in their stool. But don’t worry, understanding the reasons behind it can help you prevent this from happening.

Dehydration is a common culprit of constipation in cats. When your cat isn’t drinking enough water, their stools can become hard and dry, making it difficult for them to pass. This can lead to injury in the rectum and anus when they do try to go, resulting in bleeding in the stool. That’s why ensuring your cat always has access to fresh water is crucial. Encourage them to drink regularly by placing multiple water bowls around the house.

Another reason for constipation may be a lack of fiber in their diet. Fiber helps keep the digestive tract moving smoothly, and without it, your cat may struggle to pass their stool. It’s essential to ensure that your cat’s diet is balanced and includes enough fiber-rich foods like canned pumpkin or fiber supplements.

If you notice your cat straining in the litter box, having infrequent bowel movements, or passing small, hard stools, they may be constipated. Don’t ignore these signs as it can lead to further health complications if left unchecked. Instead, seek veterinary care promptly.


When your cat experiences diarrhea with blood in their stool, it can be alarming and cause concern. But don’t fret, we’re here to help you understand the possible causes of this digestive problem.

Diarrhea is one of the most common digestive issues in cats, characterized by loose or watery stools. It can stem from various factors such as bacterial infections, dietary changes, or stress. When your cat has diarrhea with blood in their stool, it’s vital to understand the underlying causes.

One of the most frequent reasons for bloody diarrhea in cats is colitis. This condition is an inflammation of the colon that can cause bloody stools and diarrhea. It can result from different factors such as parasites, food allergies, and inflammatory bowel disease, making your cat experience abdominal pain and vomiting.

Another likely cause of bloody diarrhea in cats is viral or bacterial infections. These infections can damage the digestive tract, leading to blood in the stool. Some of these infections are contagious and pose a risk to other cats in the household, so it’s important to be cautious.

Lastly, certain medications or treatments can also lead to bloody diarrhea in cats. For instance, antibiotics can disrupt the natural balance of bacteria in your cat’s gut and cause diarrhea with blood.

If you observe that your cat has diarrhea with blood in their poop, take them to the veterinarian promptly. The vet will perform a physical exam and may request additional tests to determine the underlying cause of the diarrhea and blood in the stool.

Treatment will depend on the underlying cause but may include medication, dietary changes or supportive care such as fluids. Regardless of the treatment recommended by the veterinarian, it’s crucial to monitor your cat’s symptoms closely and keep them hydrated throughout the recovery process.

Infection or Inflammation

One potential culprit for this unsettling occurrence is infection or inflammation in their digestive tract. Infection happens when harmful bacteria or viruses invade the intestines, causing irritation and inflammation. Meanwhile, inflammation is the body’s natural response to injury or infection and can lead to ulcers or lesions in the digestive tract.

There are various infections that can result in blood in a cat’s feces, including bacterial infections like salmonella or E. coli, viral infections such as feline panleukopenia virus, and parasitic infections like Giardia or coccidia. Inflammation can be triggered by different factors such as stress, dietary changes, or allergies.

If your cat is experiencing an infection or inflammation, they may display symptoms such as diarrhea, vomiting, loss of appetite, and lethargy. It is crucial to take your cat to the veterinarian as soon as possible to determine the root cause of the problem and receive appropriate treatment.

Treatment for infection or inflammation may include antibiotics, anti-inflammatory medications, and changes in diet. It is important to follow your veterinarian’s instructions carefully and keep a close eye on your furry friend for any changes in their symptoms.

Ingested Objects or Toxic Substances

There are many potential causes of this issue, and one of them is ingested objects or toxic substances. Let’s take a closer look at what this means for your feline companion.

Cats, especially kittens, are known for their curious and playful nature. They love to explore the world around them and may ingest anything they can get their paws on – from small toys to string and other foreign objects. Unfortunately, these objects can cause serious damage to their digestive system if swallowed. The resulting irritation and inflammation can lead to ulcers or lesions in the intestines, which can cause bloody stools.

Toxic substances are another culprit behind bloody stools in cats. Household cleaners, pesticides, and certain human medications are all examples of toxic substances that can be dangerous to cats if ingested. To keep your furry friend safe, make sure to keep these items well out of your cat’s reach. And if you suspect your cat has consumed any toxic substance, contact your veterinarian immediately.

If you notice symptoms such as vomiting, diarrhea, dehydration, lethargy, or loss of appetite alongside the bloody stools, it’s critical to seek veterinary care immediately. Depending on the severity of the situation, treatment may include surgery to remove the foreign object or medication to treat the toxicity. In some cases, hospitalization may be necessary to provide supportive care until your cat recovers.

Prevention is always better than cure when it comes to ingested objects or toxic substances causing bloody stools in cats. Keep hazardous items out of reach and supervise your cat’s playtime closely. Regular check-ups with your veterinarian can also help detect any potential health issues before they become more serious.

Serious Underlying Conditions

While it could be caused by something as simple as ingesting an object or toxic substance, there are also serious underlying conditions that could be the source of this symptom. These conditions include inflammatory bowel disease, cancer, and viral infections such as feline leukemia virus and feline immunodeficiency virus.

Inflammatory bowel disease is a chronic condition that affects the digestive tract and can cause symptoms like vomiting, diarrhea, and weight loss. Cancer can also lead to vomiting and weight loss, as well as changes in appetite and behavior. Feline leukemia virus and feline immunodeficiency virus are viral infections that can weaken a cat’s immune system, making them more susceptible to other infections and illnesses. In addition, these viruses can also cause gastrointestinal symptoms like vomiting and diarrhea. If left untreated, these viral infections can lead to severe health problems.

It’s important to keep in mind that while serious underlying conditions can be a reason for blood in your cat’s poop, other factors like dietary changes or stress can also contribute to this symptom. Therefore, it’s critical to have your cat examined by a veterinarian if you notice blood in their stool. A veterinarian will be able to determine the underlying cause and provide appropriate treatment.

What to Do When You Notice Blood in Your Cat’s Poop

As a cat parent, seeing blood in your cat’s poop can be distressing. Here are some steps you should take when you notice this issue.

Step 1: Observe Your Cat’s Behavior

The first step is to observe your cat’s behavior. Is your cat still eating and drinking normally? Is your cat acting lethargic or showing signs of pain? These observations can help your veterinarian determine the severity of the issue.

Step 2: Schedule an Appointment with Your Vet

The next step is to schedule an appointment with your veterinarian. This visit is essential to get a proper diagnosis of the underlying cause of the blood in your cat’s poop. During the appointment, your vet will perform a thorough physical exam and request a stool sample for analysis. They may also recommend additional diagnostic tests, such as blood work or imaging studies, to determine the root cause of the bleeding.

Step 3: Follow Your Vet’s Recommendations for Treatment

Depending on the cause of the blood in your cat’s poop, treatment options can vary. If it is due to a dietary change or food intolerance, switching to a different type of food may be enough to resolve the issue. However, if it is due to a more serious condition such as inflammatory bowel disease or cancer, more extensive treatment may be necessary. It’s crucial to follow your veterinarian’s recommendations for treatment and follow-up care.

Step 4: Provide Supportive Care at Home

In addition to veterinary care, there are some steps you can take at home to support your cat’s digestive health. Ensure that your cat has access to clean water at all times, and feed them high-quality, easily digestible food. Avoid giving them table scraps or treats that could upset their digestive system. Incorporating probiotics or digestive enzymes into their diet may also be helpful.

Step 5: Monitor Your Cat’s Health

Finally, it’s essential to monitor your cat’s health and behavior after treatment. Your veterinarian may recommend periodic check-ups or ongoing monitoring and management to ensure your cat stays healthy and comfortable.

The Importance of Seeking Veterinary Attention

This means taking their health seriously and seeking veterinary attention whenever you notice any unusual symptoms, including blood in their stool.

While it’s easy to dismiss blood in a cat’s poop as a minor issue, it can actually indicate a wide range of health problems, both minor and serious. For instance, intestinal parasites like worms or coccidia can cause bleeding in the intestines and lead to more severe health concerns if left untreated. More serious issues such as inflammatory bowel disease (IBD), tumors, infections, and food allergies can also manifest as blood in your cat’s stool.

That’s why it’s crucial to seek prompt veterinary attention if you notice any bloody stools from your feline buddy. Your vet will perform diagnostic tests and exams to determine the underlying cause of the bleeding and recommend appropriate treatment options to ensure your cat stays happy and healthy.

Remember that catching any potential health issues early on is key to ensuring your cat’s long-term wellness. By seeking veterinary attention at the first sign of unusual symptoms, you’ll be able to provide the best possible care for your furry friend and avoid any unnecessary complications.

Preventative Measures to Keep Your Cat Healthy and Happy

The good news is that there are preventative measures you can take to achieve this goal and reduce the risk of blood in their poop.

Firstly, a well-balanced diet that is appropriate for your cat’s age, size, and activity level is crucial. This will help prevent gastrointestinal issues that may cause blood in their stool. Make sure to provide fresh water at all times as dehydration can lead to constipation and blood in their poop.

Secondly, regular exercise is essential for maintaining your cat’s health and preventing digestive issues. Physical activity not only helps keep your cat fit, but it also prevents boredom and stress which can lead to gastrointestinal problems.

Thirdly, don’t skip out on routine veterinary checkups. Such checkups can help identify any underlying medical conditions that may cause blood in their stool. Your vet can also recommend preventative measures such as deworming medications or vaccinations to keep your cat healthy.

Fourthly, cleanliness is key when it comes to preventing blood in your cat’s poop. Ensure that their litter box is clean and free of bacteria buildup that can lead to infections or inflammation in their digestive tract.

By following these preventative measures, you can play an active role in keeping your cat healthy and happy. However, if you do notice any blood in your cat’s stool, seek veterinary care immediately as it could be a sign of a serious medical condition.


In conclusion, discovering blood in your cat’s poop can be a distressing situation that requires immediate action. As a devoted pet owner, it’s essential to comprehend the most common reasons for bloody stool in cats and promptly seek veterinary help if you notice any unusual changes in their behavior or health.

There are numerous causes of bloody stool, including gastrointestinal infections, parasites, food intolerance, inflammatory bowel disease, cancerous growths, foreign objects, constipation, diarrhea with blood, infection or inflammation, and ingested objects or toxic substances. However, some severe underlying conditions like viral infections and inflammatory bowel disease could also be the source of this symptom.

To maintain your cat’s health and prevent such issues from occurring in the future, it is crucial to take preventative measures such as providing a well-balanced diet appropriate for your cat’s age and activity level. Regular exercise can also prevent boredom and stress-induced digestive issues.

Additionally, routine veterinary checkups can identify any underlying medical conditions early on. Ensuring that their litter box is clean can prevent bacteria buildup that may lead to infections or inflammation in their digestive tract.

Remember that early detection of any illness can lead to better outcomes for your feline friend.
