Cat Throwing Up Bile? Cat Vomit Color Chart & Causes

You hear your cat retching, reach for paper towels, and find a yellow puddle on the floor. Yesterday it was food. This time there’s barely anything solid in it. What changed?

A cat vomit color chart helps you identify what may be coming up. Yellow or green fluid often contains bile, clear liquid may be water or stomach fluid, and orange or brown material often contains food. Pink, red, or dark coffee-ground-like material raises concern for blood.

Start with the color, then look at the texture, timing, and how your cat behaves afterward. Together, those details tell a more useful story.

What Your Cat’s Vomit Color Could Mean

Yellow Vomit: Why Is My Cat Throwing Up Bile?

Bile is a digestive fluid produced by the liver. Mixed with stomach fluid, it can make vomit look pale yellow, mustard-colored, or slightly greenish.

A typical scenario is finding a small yellow puddle before breakfast, several hours after dinner. Bile can also appear after repeated vomiting has emptied the stomach. Check whether your cat missed a meal, ate less than usual, or already brought up food earlier. These situations can produce a similar-looking puddle for different reasons.

Green Vomit: Bile or Something Your Cat Ate?

Green liquid may contain bile. Green vomit with obvious leafy pieces points toward swallowed grass or plant material. Food dyes can also affect the shade.

Check nearby plants and bouquets for bite marks. Photograph any plant your cat may have chewed so it can be identified. The plant’s identity matters more than how much green material appears in the vomit.

White Foam: What Are Those Bubbles?

White vomit often looks like a small mound of froth surrounded by watery fluid. Air mixes with digestive secretions during retching, creating the bubbles.

This can happen when little food remains in the stomach and may accompany digestive irritation. Watch the sequence: bringing up dinner followed by foam suggests the stomach has emptied during successive episodes. Foam by itself offers limited information about the underlying cause.

Clear Liquid: Did Your Cat Just Drink?

Clear vomit may contain water your cat recently swallowed or fluid from the stomach. You might notice a transparent puddle with a little mucus or a few bubbles.

Record whether it happened immediately after drinking and whether your cat visibly heaved. Repeatedly returning to the bowl and bringing water back up is an important pattern to recognize.

Orange or Brown Vomit: Look Closely at the Texture

Kibble and wet food often give vomit a tan, orange, or brown appearance. Recognizable chunks may appear soon after a meal; partially digested food can look softer and more uniform.

Compare it with what your cat ate. Brown food-colored material looks different from dark granules resembling wet coffee grounds. Those granules may be digested blood and belong in the urgent category.

Pink, Red, or Black Vomit: Possible Bleeding

A small amount of fresh blood can turn fluid pink or leave red streaks through mucus. Larger amounts may form red clots. Partially digested blood can become dark and grainy.

Food coloring can create similar shades, so photograph the material and contact a veterinarian immediately when blood is possible. Coffee-ground-like vomit requires emergency assessment.

What If There’s Food, Hair, or Worms in It?

Food coming up immediately after eating: Watch the movement. Vomiting involves retching and abdominal contractions. Regurgitation is more passive, with food coming back up suddenly and little visible effort. Eating quickly can contribute to bringing up food; recurring episodes need investigation.

A compact roll of hair: Hairballs often look like damp, elongated bundles of fur surrounded by fluid. Note how often they appear and whether your cat has started grooming more intensely.

Pale, spaghetti-like strands: These may be roundworms. Take a photograph and ask the clinic whether to bring a sample for identification and appropriate treatment.

What Should You Do After Your Cat Throws Up?

After one episode, check whether your cat returns to their usual activities. A comfortable, alert adult cat can be watched closely at home while you note any further symptoms.

• Take a photograph before cleaning. Capture the color, texture, and any recognizable contents.
• Record the timing. Include the last meal, recent drinking, and the number of episodes.
• Keep fresh water available. Let your cat drink voluntarily.
• Check appetite and bathroom habits. Record skipped meals, diarrhea, and changes in urination.
• Review recent changes. New treats, medications, chewed plants, and damaged toys are useful clues.

Avoid forcing food or water, giving human medicines, or trying to induce vomiting. Ask for individual feeding advice if nausea continues; prolonged fasting is especially risky for kittens and cats with medical conditions.

When Does Cat Vomiting Need Veterinary Care?

Seek immediate care for suspected blood, coffee-ground-like material, severe weakness, abdominal pain, repeated vomiting that prevents water staying down, or possible ingestion of a toxin or foreign object. Suspected lily exposure is an emergency even before symptoms develop.

Arrange a prompt appointment for recurring episodes, appetite loss, weight loss, or accompanying diarrhea. Cornell’s feline health guidance recommends assessment for vomiting more frequently than once a week. Several episodes close together also warrant a prompt call.
