When your cat starts vomiting brown liquid, it's natural to feel concerned. This alarming symptom often signals a potentially serious health issue that requires immediate veterinary attention. Understanding the causes, symptoms, and appropriate responses can help you make informed decisions about your cat's health.
In this comprehensive guide, we'll explore why cats vomit brown liquid, what it means, and when you should seek emergency veterinary care. This information could be crucial for your cat's well-being, as brown vomit often indicates the presence of digested blood in the gastrointestinal tract.
Common Causes of Brown Vomit in Cats
Several serious medical conditions can cause a cat to vomit brown liquid:
Gastrointestinal Bleeding
The most common reason for brown vomit is the presence of digested blood in the stomach, often appearing like coffee grounds. This can result from ulcers, tumors, or trauma to the digestive tract.
Internal Organ Disease
Liver disease, kidney failure, or pancreatic inflammation can lead to brown vomiting. These conditions often require immediate medical intervention and long-term management.
Foreign Body Obstruction
When cats swallow non-food items, they can become stuck in the digestive tract, causing damage and bleeding that results in brown vomit.

Watch for these additional symptoms that often accompany brown vomit:
- Lethargy and weakness
- Loss of appetite
