Blood in Cat Stool: Understanding the Causes and Treatment



As a cat owner, you rely on your furry friend to keep you entertained, cuddled, and happy. When your cat starts exhibiting abnormal behavior or signs of illness, it’s natural for you to feel concerned.

One of the most common symptoms that pet owners report is blood in their cat’s stool. This can be an alarming sight, but it’s essential to understand the different causes of bloody stool in cats, as well as what you can do to help your feline friend.


1. Diarrhea

Diarrhea can cause irritation and bleeding in your cat’s gastrointestinal (GI) tract, leading to soft, watery stools that may contain fresh blood.

Diarrhea is usually caused by infections, dietary changes, or allergies. Some cats may also have emotional stress that can lead to diarrhea.

2. Constipation

When your cat strains to defecate because of hard stools, they may rupture blood vessels in their anus, rectum, or colon, leading to bloody diarrhea.

Constipation is also associated with GI problems, such as inflammatory bowel disease or tumors, among others. 3.


Polyps, cysts, and tumors in your cat’s GI tract can cause internal bleeding, leading to bloody stools. These growths can be benign or malignant and can occur in different parts of the digestive system.

4. GI Problems

GI problems, such as ulcers, colitis, and gastritis, can cause dark-colored or tarry stool that has a significant amount of blood.

These problems often occur in the stomach or small intestine and can be caused by infections, medications, or poor diet. 5.


A urinary tract infection (UTI) can also lead to blood in your cat’s stool. UTIs can cause inflammation, irritation and bleeding in the urinary tract, leading to droplets of blood being visible in the stool.


If you notice that your cat has bloody stool, the best thing to do is to contact your vet immediately. Abnormal bowel movements are a sign that something is not right, and your cat could be suffering from an illness or an underlying medical condition that requires immediate attention.

Your vet will perform a full examination, including taking a stool sample, to determine the cause of the problem.


The stool sample will be examined for parasites, bacteria, fungal infections, or other underlying health issues. Your vet will also check for organ function, abdominal radiographs, and ultrasound to get a clearer picture of what’s happening inside your cat’s body.

The diagnostic tests will help your vet to design an appropriate treatment plan for your cat.


The treatment options for bloody stool depend on the underlying cause and severity of your cat’s condition.

In most cases, your vet will prescribe GI support medication and probiotics to help with diarrhea and constipation. Additionally, your cat may need a diet change to a more fiber-rich diet that promotes healthy digestion.

Parasite screening will also help to ensure that your cat is not harboring any harmful organisms that may contribute to bloody stool. For constipation, your cat may require a laxative or additional fiber in their diet.

Along with this medication and dietary changes, careful monitoring and attention to your cat’s health can help prevent further issues and stop the symptom from returning.


In conclusion, blood in your cat’s stool is not a problem you should ignore. Instead, it’s a sign that something is not functioning correctly, and your cat could be in a lot of pain.

If you notice signs of abnormal bowel movements, such as diarrhea, constipation or straining to defecate, it is important to contact your vet as soon as possible. With a full examination and diagnosis, treatment options can be applied to address the root cause of the bloody stool and help your cat recover to good health.

In summary, blood in your cat’s stool can be caused by several factors like diarrhea, constipation or GI problems and it’s important to seek veterinary help immediately if you notice any abnormal bowel movement. A full examination and diagnosis will be done to determine the underlying cause and an appropriate treatment plan will be prescribed.

Preventive measures like parasite screening and a fiber-rich diet can help to keep your cat healthy. Taking prompt action can help to prevent further issues and ensure your feline friend lives a happy and healthy life.
