Why Is My Cat Pooping Blood?<\/h2>\n\n\n\n
![\"\"](\"https:\/\/maven.pet\/all-about-pets\/wp-content\/uploads\/2025\/09\/why_is_my_cat_pooping_blood_why.jpg\")
<\/figure>\n\n\n\nThe usual culprits for a cat to poop blood are a sudden food switch, stress-colitis, parasites, constipation or tiny anal tears, food intolerance, bacterial infections, inflammatory bowel disease, ulcers, polyps\/tumors, or blood-thinning medications or toxins.<\/p>\n\n\n\n
The blood in poop manifests itself in two forms. The fresh, bright-red blood comes from the lower bowel (hematochezia) or black, tarry poop from bleeding that takes place higher up in the gut (melena). <\/p>\n\n\n\n
Why Is My Cat Pooping Blood but Acting Normal?<\/h2>\n\n\n\n
If your cat seems totally fine but you\u2019re spotting blood in the poop, it could be that it\u2019s just a mild irritation in the lower gut. For example, it could be a case of constipation or a small anal fissure. Even stress and parasites can lead to these small streaks of bright-red blood or mucus. <\/p>\n\n\n\n
Now, it\u2019s good that your cat is acting normal, but it\u2019s important to call the vet if blood appears in 2\u20133 consecutive poops or you see clots or lots of blood, or the stool turns black\/tarry. These can indicate a deeper underlying issue. If the cat starts to vomit or its gums become pale, take it to the vet immediately. It\u2019s good to snap a photo of the stool and take a fresh sample so that the vet can run some lab work. <\/p>\n\n\n\n

Here\u2019s what usually sits behind blood in a cat\u2019s poop and how it tends to look:<\/p>\n\n\n\n
- \n
- Constipation & tiny anal tears: <\/strong>Constipation will make cats poop hard, dry pellets with bright-red streaks. That kind of stool can make the yelp from time to time or \u201cbutt scoot\u201d, so look for these signs. <\/li>\n\n\n\n
- Diet upset: A change in diet can result in softer stools<\/strong>, accompanied by red mucus. Otherwise, the stool should look normal. <\/li>\n\n\n\n
- Stress<\/strong>: If your cat is under stress, for example, on New Year\u2019s Eve, due to fireworks or you\u2019ve moved homes, it can lead to small red flecks in the stool. <\/li>\n\n\n\n
- Parasites (worms, <\/strong>coccidia<\/strong><\/a>, <\/strong>giardia<\/strong><\/a>): <\/strong>Intestinal parasites latch onto the lining of the intestine and damage it, which can lead to smelly, soft, and bloody stools. The condition is more common in outdoor cats and kittens. <\/li>\n\n\n\n
- Food intolerance: <\/strong>If you\u2019ve recently introduced a new ingredient into your cat\u2019s diet and you\u2019ve started to notice diarrhea and blood in the stool, eliminate that ingredient right away. <\/li>\n\n\n\n
- Bacterial infection<\/strong>: Bacteria, such as Salmonella, that infect the GI tract can cause bleeding in the stool. Usually, you\u2019ll see a sudden diarrhea with blood and a foul odor, so it\u2019s an immediate cause for concern. <\/li>\n\n\n\n
- Inflammatory bowel disease (IBD)<\/a>: The inflammation in the bowels can lead to recurrent soft stools with red mucus and is accompanied by weight loss, a decreased appetite, and fluctuations in symptoms.<\/li>\n\n\n\n
- Polyps or tumors: <\/strong>Polyps and tumors in the digestive tract can cause bleeding and a bloody stool. <\/li>\n\n\n\n
- Foreign bodies:<\/strong> If your cat has swallowed something it shouldn\u2019t have, like a toy or a bone, it can cause red streaks or mixed blood in the stool. <\/li>\n\n\n\n
- Medications and toxins:<\/strong> Exposure to toxins, like rodenticide, or strong medications, like steroids, can cause blood to appear in the stool. <\/li>\n<\/ul>\n\n\n\n
When It\u2019s an Emergency<\/h2>\n\n\n\n
![\"\"](\"https:\/\/maven.pet\/all-about-pets\/wp-content\/uploads\/2025\/09\/why_is_my_cat_pooping_blood_emergency.jpg\")
<\/figure>\n\n\n\nYou need to seek immediate veterinary help if the bleeding persists over the next 24 to 48 hours, the stool is black, and there\u2019s more than just a smear of blood in the stool. Additionally, if your cat also shows signs of pain, there\u2019s fever, and its gums are turning pale, you need to seek vet care. <\/p>\n\n\n\n
All of these signs can indicate more serious condition, like tumor or poison. Don\u2019t give your cat human medications and bring a sample of the stool for analysis. <\/p>\n\n\n\n
How Vets Diagnose Blood in Stool<\/h2>\n\n\n\n
Vets usually do a physical exam, followed by some fecal tests to see if there are any parasites or an infection. They may add bloodwork, like a full CBC and do an X-ray of the GI tract to check for foreign bodies or masses. Occassionally, they might do an endoscopy where a small camera is inserted in the digestive track to look for IBD, polyps and tumors. <\/p>\n\n\n\n
They could use all the help they can get, so if you can bring data from a pet health tracker<\/a>, that can help diagnose the condition faster. <\/p>\n\n\n\n
\u201cEven if your cat seems fine, blood in the stool should never be ignored. It may be the first sign of illness, and early evaluation can make a big difference in treatment.\u201d<\/em> – Dr. Joana Babo, DVM at Maven Pet <\/p>\n\n\n\n
