Cat Vomiting Clear Liquid: Main Causes
A cat vomits clear liquid for several reasons, often benign… but not always.
The Most Frequent Causes
- Empty stomach
- Difficult digestion
- Stress
- Hairballs
A Common Phenomenon
When the stomach is empty for too long, it produces bile which can irritate the lining and cause vomiting.
According to the Cornell Feline Health Center, occasional vomiting is common in cats, but should be monitored if it becomes regular.

Bile Vomiting in Cats: Explanation
A cat vomits clear or slightly yellowish liquid when it expels bile.
Why this happens
Bile is produced by the liver and stored in the gallbladder. When it goes back up into the stomach, it can cause vomiting.
- Prolonged fasting
- Irregular meals
- Excess acidity
A Natural Mechanism
This type of vomiting is often observed in the morning or after a long period without eating.
| Type of Vomiting | Color | Probable Cause |
|---|---|---|
| Clear liquid | Clear | Empty stomach |
