My cat is throwing up blood — why?
If you’ve ever noticed your cat throwing up blood, it can be a deeply distressing experience. Seeing any sign of illness in your furry friend is alarming, and hematemesis (the medical term for vomiting blood) is no exception.
While there are many potential causes, it’s crucial to understand the symptoms, underlying reasons, and treatment options to ensure your cat gets the care they need.
While there are many potential causes, it’s crucial to understand the symptoms, underlying reasons, and treatment options to ensure your cat gets the care they need.
Let’s explore why this might happen and what you can do to help your beloved companion.
What Is Hematemesis in Cats?
Hematemesis refers to the presence of blood in a cat’s vomit. It can vary in appearance from fresh, bright red blood to dark, coffee-ground-like material, which indicates digested blood. This condition is distinct from regular vomiting, which may involve undigested food or hairballs.
Cats can experience hematemesis for a variety of reasons, ranging from minor irritations to serious underlying health conditions. Recognizing it early is essential to prevent further complications.
Symptoms of Hematemesis in Cats
While the sight of blood in your cat’s vomit is the primary symptom, other signs often accompany hematemesis. Keep an eye out for:
- Changes in the color or texture of vomit, as noted in a cat vomit color chart (e.g., bright red or dark brown).
- Excessive drooling or nausea.
- Lethargy or lack of energy.
- Loss of appetite.
- Weight loss over time.
- Visible signs of pain or discomfort, such as hiding or reluctance to move.
If your cat displays any of these symptoms, it’s important to consult a veterinarian immediately to rule out serious conditions.
Common Causes of Cats Throwing Up Blood
Hematemesis in cats can result from a wide range of causes, including:
Gastrointestinal Issues
- Ulcers: Damage to the stomach lining caused by medications, stress, or other factors.
- Foreign Objects: Ingested items, such as string or small toys, that irritate the digestive tract.
- Inflammation: Conditions like gastritis, which inflame the stomach lining.
Toxins or Poisons
Exposure to substances like certain plants, antifreeze, or medications not intended for cats can lead to internal bleeding.Trauma
Injuries from falls, accidents, or even rough play can damage internal organs, leading to blood in vomit.Diseases
- Liver Disease: Impaired liver function can cause bleeding disorders.
- Kidney Disease: Toxins that accumulate due to kidney issues may lead to gastrointestinal bleeding
- Cancer: Tumors in the stomach or intestines can erode blood vessels, causing hematemesis.
Parasites or Infections
Hookworms, roundworms, and certain bacterial or viral infections can irritate the gastrointestinal tract.
When to Worry About Your Cat Vomiting Blood
So, how do you know if your cat’s condition requires immediate attention? Here are some key indicators:
- Persistent vomiting or recurring episodes within 24-48 hours.
- Lethargy or noticeable weakness.
- Blood appearing alongside other symptoms like diarrhea or labored breathing.
- Significant weight loss or dehydration.
These signs warrant a trip to the vet as soon as possible.

How Is Hematemesis Diagnosed in Cats?
When you take your cat to the vet, they will perform a thorough examination to identify the underlying cause of the hematemesis. Here’s what you can expect:
Medical History and Physical Exam
Your vet will ask about your cat’s diet, recent behavior, and any potential exposure to toxins. A physical exam may reveal signs of abdominal tenderness or dehydration.
Diagnostic Tests
To pinpoint the cause, your vet may recommend:
- Bloodwork: Identifies infections, anemia, or liver/kidney dysfunction.
- X-rays or Ultrasounds: Detects tumors, blockages, or internal injuries.
- Endoscopy: Allows visualization of the stomach lining for ulcers or foreign objects.
- Fecal Tests: Checks for parasites.
Treatment Options for Cats Throwing Up Blood
Treatment depends on the diagnosis. Here are some common approaches:
Medications
- Antibiotics: For bacterial infections.
- Anti-Nausea Drugs: To control vomiting.
- Gastroprotective Agents: Medications like sucralfate to coat and protect the stomach lining.
Dietary Changes
- Transitioning to a bland diet, such as boiled chicken and rice, to reduce stomach irritation.
Surgery
- In cases of foreign object ingestion or tumors, surgical intervention may be required.

My pet has the following symptoms:
Vomiting Blood
Two of my cats are vomiting blood that is bright red. Neither one has been outside or exposed to plants or poison. I did give them canned meat last night and they don't usually have it. The only emergency vet near by is an hour and a half away. Is there anything I can do or watch for to help them or should I go to the vet?

Hello, vomiting blood is very concerning and the best thing that your cats see a vet. This meat could have been bad and upset their stomachs. Usually, when a pet is vomiting, I recommend a bland diet. But vomiting blood could be an indication of a GI ulcer or something more serious wrong that would need immediate vet attention.

Thank you for your question.
Vomiting blood is a problem, I see why you are concerned. If he/she is still having this problem, it would be best to have your veterinarian look at your pup to make sure that all is okay, and see if any treatment is needed.
I hope your puppy is okay!
