It can be alarming to witness your cat vomiting, and even more concerning when it’s a yellow liquid. Vomiting, in general, is a forceful expulsion of stomach contents through the mouth, and cats can vomit various substances – from hairballs to undigested food, and sometimes, a yellow liquid. This yellow liquid is often bile, and understanding why your cat might be vomiting it is crucial for their health and well-being.
Any instance of vomiting in cats warrants attention, especially if accompanied by other signs like decreased appetite or lethargy. Let’s delve into the common reasons behind cats throwing up yellow liquid, often identified as bile, and determine when a trip to the veterinarian is necessary.
Decoding Yellow Vomit: What is Bile?
If you notice your Cat Vomiting Yellow Liquid, it’s highly likely to be bile. Bile is a yellowish-green fluid produced by the liver and stored in the gallbladder. Its distinctive yellow color comes from bilirubin, a byproduct of the liver’s breakdown of old red blood cells.
Bile plays a vital role in digestion, being released during meals to aid in the breakdown of fats. However, when a cat’s stomach remains empty for extended periods, bile can accumulate and irritate the stomach lining, triggering vomiting of this yellow fluid.
Occasionally, yellow vomit might also indicate that your cat has ingested something yellow, such as certain foods with artificial coloring or a yellow household object.
However, in most cases, when a cat vomits yellow bile, it’s primarily due to an empty stomach and bile reflux. While a single episode of vomiting yellow bile might not always be an emergency, especially if your cat is otherwise behaving normally, it’s important to monitor for any additional symptoms.
Vomiting yellow liquid can become a medical emergency if it’s linked to an underlying health problem, ingestion of toxic substances, or intestinal blockages. These situations are usually accompanied by other concerning symptoms like lethargy, reduced appetite, and abdominal discomfort, requiring immediate veterinary attention.
If you are unsure about the cause of your cat’s yellow vomit, or if it’s accompanied by other symptoms, it’s always best to consult with a veterinarian promptly. For non-emergency situations where your cat vomits yellow liquid without additional concerning symptoms, consider utilizing online veterinary services to assess if a vet visit is needed.

Common Causes of Cats Vomiting Yellow Liquid
There are several reasons why your cat might vomit yellow liquid, ranging from minor dietary issues to more serious medical conditions. If your cat is consistently vomiting yellow liquid, consulting your veterinarian is crucial to pinpoint the exact cause and determine if treatment is necessary.
Let’s explore some of the most common reasons behind cats throwing up yellow liquid:
1. Hairballs
Hairballs are a frequent occurrence in cats, particularly those with longer fur. Cats are meticulous groomers, and their tongues have tiny, backward-facing barbs that help them remove loose hair. During grooming, cats inevitably swallow hair. While most of this hair passes through their digestive system, some can accumulate in the stomach.

Hair is indigestible, and if it doesn’t move into the intestines, it can form a hairball in the stomach. This accumulation can irritate the stomach lining, leading to vomiting to expel the hairball. Often, these hairballs are vomited up with some bile, resulting in yellow liquid.
Occasional hairball vomiting, perhaps once a week, is generally not alarming. However, if your cat is frequently vomiting hairballs, it could indicate an underlying issue. Consulting your vet about hairball prevention is advisable. Special diets and oral medications can help minimize hairball formation.
If your cat is vomiting bile, refusing food, and exhibiting weight loss, it could signal a more serious problem – a hairball causing an intestinal blockage. This is a serious situation requiring immediate veterinary intervention.
2. Empty Stomach and Bile Buildup
As mentioned earlier, an empty stomach is a primary reason for cats vomiting yellow liquid. When a cat goes for extended periods without food, bile can build up in the stomach. This bile accumulation can irritate the stomach lining, triggering vomiting.
This scenario can occur if your cat skips meals, is fasting before surgery, or suffers from bilious vomiting syndrome (BVS). BVS is a condition where bile refluxes into the stomach, causing irritation and vomiting, particularly in the morning or after long intervals without food.
To prevent bile-related vomiting, ensure your cat receives regular meals. Cats with sensitive stomachs might benefit from smaller, more frequent meals throughout the day to avoid prolonged periods of an empty stomach.
3. Underlying Health Conditions
Sometimes, vomiting yellow liquid is an early indicator of an underlying medical condition that requires veterinary treatment. Several health issues can manifest as yellow vomit in cats:
- Inflammatory Bowel Disease (IBD): Inflammation of the digestive tract can lead to various symptoms, including vomiting, sometimes with bile.
- Pancreatitis: Inflammation of the pancreas can cause vomiting, among other signs.
- Liver Disease: As bile is produced in the liver, liver dysfunction can disrupt bile flow and contribute to vomiting.
- Kidney Disease: Kidney problems can also lead to vomiting as a secondary symptom.
- Hyperthyroidism: An overactive thyroid gland can sometimes cause gastrointestinal upset, including vomiting.
- Gastroenteritis: Inflammation of the stomach and intestines, often caused by infections or dietary indiscretion, can result in vomiting.
Less commonly, conditions like hiatal hernias and acid reflux can also cause cats to vomit yellow liquid.
Vomiting yellow liquid in cats can be a subtle sign of a more significant health issue that needs veterinary diagnosis and care.
When Veterinary Care is Necessary
As a pet owner, it’s crucial to know when cat vomiting yellow liquid requires a vet visit. If you are uncertain about the cause of your cat’s vomiting, or if it persists or worsens, contacting your veterinarian is always the safest course of action.
For instance, if your cat vomits bile once, but you know they missed a meal and are otherwise acting normally, the vomiting is likely due to an empty stomach. However, if your cat exhibits other symptoms alongside vomiting bile, such as:
- Lethargy or weakness
- Loss of appetite or refusal to eat
- Diarrhea
- Abdominal pain or tenderness
- Dehydration (dry gums, sunken eyes)
- Weight loss
- Changes in behavior
These accompanying symptoms could indicate an underlying health condition that needs prompt veterinary attention.
In any situation where you are concerned about your cat’s health, especially when vomiting yellow liquid is involved, it is always best to err on the side of caution and consult with your veterinarian. They can accurately diagnose the cause of the vomiting and recommend the appropriate treatment plan to ensure your feline companion’s well-being.
