Cats are known to vomit occasionally, and while it can sometimes be a minor issue like expelling a hairball, the color of a cat’s vomit can provide important clues about their health. Different vomit colors can signal various conditions, ranging from simple digestive upset to more serious medical issues. Paying attention to the color and consistency of your cat’s vomit can help you determine when to take action and when a vet visit is necessary.
Common Causes of Vomiting in Cats
Cats may vomit for several reasons, and the cause of the vomiting often determines the appearance of the vomit itself. Some of the common causes of vomiting in cats include:
- Hairballs
- Eating too fast or dietary indiscretions (eating non-food items)
- Food allergies or intolerances
- Gastrointestinal inflammation or infection
- Parasites
- Kidney or liver disease
- Stress or anxiety
Understanding what might trigger vomiting in your cat can help you identify the underlying cause of the color and type of vomit.
Cat Vomit Color Chart
The color of your cat’s vomit can indicate different health conditions or reactions. Below is a guide to what the various colors of vomit may mean:
Clear or Foamy
Clear or foamy vomit usually indicates that your cat is vomiting stomach acid or bile due to an empty stomach. This often occurs early in the morning or late at night when your cat has gone several hours without eating. If this happens infrequently, it’s generally not a cause for concern.
Possible Causes: Acid reflux, an empty stomach, or mild nausea.
What to Do: Try feeding smaller, more frequent meals to prevent the buildup of stomach acid.
Yellow or Green
Yellow or green vomit often indicates the presence of bile, which is produced in the liver and stored in the gallbladder. Bile vomit typically occurs when a cat is vomiting on an empty stomach or has gastrointestinal irritation. If your cat vomits bile frequently, it could be a sign of liver or digestive issues.
Possible Causes: Bile due to an empty stomach, gastrointestinal issues, or liver problems.
What to Do: If this occurs regularly, consult your vet for a check-up.
Brown
Brown vomit can be concerning, as it may indicate the presence of digested blood, especially if your cat has a gastrointestinal ulcer or internal bleeding. In other cases, it might suggest your cat has eaten something brown, such as dirt or feces.
Possible Causes: Internal bleeding, ingestion of foreign material, or severe gastrointestinal upset.
What to Do: Immediate veterinary attention is recommended if the vomit is brown and your cat appears lethargic or shows other signs of illness.
Red or Pink
Red or pink vomit is a clear indication that there is fresh blood present. This could be due to damage or irritation in the esophagus, mouth, or stomach. Cats that have ingested sharp objects or have ulcers may vomit blood.
Possible Causes: Ulcers, trauma, or ingestion of sharp objects.
What to Do: Seek emergency veterinary care as soon as you notice blood in your cat’s vomit.
White and Foamy
White foamy vomit is commonly associated with hairballs, as cats will often gag or retch when trying to expel one. This type of vomit can also indicate that your cat is experiencing mild nausea or excess stomach acid.
Possible Causes: Hairballs, mild nausea, or stomach acid.
What to Do: Offer hairball remedies or increase fiber in your cat’s diet. If the vomiting persists, consult a vet to check for other gastrointestinal issues.

Green or Yellow Mucus
Green or yellow mucus in your cat’s vomit may point to gastrointestinal irritation or inflammation. This could also indicate bile or a gallbladder issue. Vomit with mucus may suggest that your cat’s body is producing excess fluids in response to inflammation.
Possible Causes: Intestinal inflammation, bile issues, or infection.
What to Do: Monitor your cat closely, and if the problem continues, visit your vet to rule out more serious conditions.
Black or Coffee Grounds
Black vomit or vomit that resembles coffee grounds is usually digested blood. This color is a sign of gastrointestinal bleeding, which could stem from ulcers or severe infections.
Possible Causes: Bleeding ulcers, tumors, or severe gastrointestinal issues.
What to Do: Take your cat to the vet immediately if you notice black or coffee ground-like vomit.
Undigested Food
Vomiting undigested food typically occurs when a cat eats too fast or experiences mild digestive upset. If this happens frequently, it could indicate a more serious issue such as a blockage, food allergy, or intolerance.
Possible Causes: Eating too quickly, food allergies, or digestive obstruction.
What to Do: Use slow-feeder bowls to slow down your cat’s eating pace, and consult a vet if the vomiting persists.
Green or Plant Matter
If your cat vomits up green plant material, this usually indicates that they have been eating grass or other plants. Cats sometimes eat grass to soothe an upset stomach or induce vomiting when they feel nauseous. However, if your cat ingests toxic plants, this could lead to more serious health issues.
Possible Causes: Grass or plant ingestion, often to self-induce vomiting.
What to Do: Ensure that any houseplants in your home are non-toxic. If vomiting persists or your cat shows other signs of illness, consult your vet.
When to Be Concerned About Cat Vomiting
While occasional vomiting may not be unusual for cats, there are certain scenarios where it becomes a cause for concern:
Frequent Vomiting
If your cat is vomiting more than once or twice a week, it could indicate an underlying health problem such as inflammatory bowel disease, pancreatitis, or even organ failure. Chronic vomiting should always be investigated by a vet.
Vomiting Paired with Other Symptoms
If your cat’s vomiting is accompanied by lethargy, loss of appetite, diarrhea, or changes in behavior, this could be a sign of a serious condition. Diseases like kidney disease, liver disease, or gastrointestinal infections often present with multiple symptoms.
Vomiting Blood
The presence of blood, whether it appears fresh (red or pink) or digested (black or brown), is a medical emergency. This could indicate internal bleeding or trauma and requires immediate veterinary attention.
Dehydration
Vomiting can quickly lead to dehydration in cats, especially if they are not drinking enough water. Signs of dehydration include sunken eyes, dry gums, and lethargy. If your cat shows signs of dehydration, contact your vet immediately.
Common Causes of Vomiting by Vomit Color
Each color of vomit can point to a different cause. To recap:
- Clear/White Foamy: Stomach acid, hairballs, or mild nausea.
- Yellow/Green: Bile, gastrointestinal distress, or liver problems.
- Brown: Potential internal bleeding or ingestion of inappropriate materials.
- Red/Pink: Fresh blood from the upper gastrointestinal tract, possibly due to trauma or ulcers.
- Black/Coffee Grounds: Digested blood indicating gastrointestinal bleeding, which requires immediate attention.
- Undigested Food: Eating too quickly or potential gastrointestinal blockage.
How to Treat and Prevent Cat Vomiting
While occasional vomiting may not be a cause for alarm, taking steps to reduce it can help prevent it from becoming a chronic issue:
Dietary Adjustments
Switch to a high-quality, easily digestible diet that suits your cat’s nutritional needs. If your cat suffers from food allergies, your vet may recommend a special diet.
Hairball Remedies
For long-haired cats prone to hairballs, regular grooming and hairball prevention products can help reduce vomiting. A diet high in fiber may also help your cat pass hairballs more easily.
Hydration
Ensure your cat is drinking enough water to stay hydrated, especially after vomiting. Providing a cat water fountain may encourage more frequent drinking.
Veterinary Check-Ups
Regular vet check-ups can catch underlying health problems before they become severe. If vomiting becomes chronic, a vet can perform tests to rule out serious conditions like kidney disease or gastrointestinal disorders.
While vomiting can be a common occurrence for cats, it’s essential to monitor the color and frequency to determine if there are any underlying health concerns. Certain vomit colors, such as red, brown, or black, are major warning signs that require immediate veterinary attention. By understanding the different causes and taking steps to manage your cat’s health, you can ensure your feline companion stays happy and healthy.
