If your cat is vomiting, you’re not alone—this is one of the most common health issues cat owners face. But not all vomiting is the same. Sometimes it’s harmless, while other times it signals a serious medical problem.

Types of Cat Vomiting
Understanding the type of vomit can give important clues about what’s wrong.
- Hairball Vomiting – Cats groom themselves constantly, and swallowed fur can clump into hairballs, which are often vomited out.
- Foamy Vomit – Usually linked to stomach irritation, gastritis, or bile.
- Undigested Food Vomiting – May occur if your cat eats too fast or has digestive issues.
- Yellow or Green Vomit – Often bile; could indicate an empty stomach or liver/gallbladder issues.
- Bloody Vomit (Hematemesis) – A red flag that requires urgent veterinary care.
- Clear Liquid Vomit – Can mean stomach irritation or drinking too much water.
- Worm-Related Vomit – Sometimes parasites like roundworms can appear in vomit.
Common Causes of Cat Vomiting
Vomiting can result from many different triggers:
- Hairballs – Very common in long-haired breeds.
- Eating too fast – Food may come up undigested.
- Dietary changes – Sudden switch of food or treats.
- Food intolerance/allergy – Certain proteins or ingredients may upset your cat.
- Parasites – Worm infestations often cause vomiting.
- Toxins – Plants, chemicals, or spoiled food ingestion.
- Infections – Viral or bacterial infections can irritate the stomach.
- Foreign object – Cats may swallow toys, string, or bones, blocking the stomach.
- Chronic diseases – Kidney disease, hyperthyroidism, pancreatitis, or liver issues.
- Cancer – Though less common, tumors can cause persistent vomiting.
