Why Is My Cat Vomiting?

Vomiting is one of the most common reasons cat owners visit the vet. While occasional vomiting can be normal, frequent or severe episodes deserve attention.

Common Causes

• Hairballs: The most common cause, especially in long-haired cats. Usually produces a tubular mass of fur. See our article on hairballs

• Eating too fast: Some cats eat so quickly they regurgitate undigested food minutes later

• Dietary issues: Food sensitivities, sudden diet changes, or spoiled food

• Foreign objects: String, rubber bands, small toys — cats are curious eaters

• Parasites: Intestinal worms can cause vomiting, especially in kittens

• Toxins: Plants (lilies are extremely dangerous), chemicals, certain human foods

• Medical conditions: Kidney disease, liver issues, pancreatitis, inflammatory bowel disease

When to Worry

See your vet promptly if:

• Vomiting occurs more than 2–3 times in 24 hours

• Vomit contains blood (red or dark brown)

• Your cat is lethargic, not eating, or seems in pain

• Vomiting is accompanied by diarrhea

• Your cat may have ingested something toxic

• Vomiting has been happening regularly for more than a week

Simple Solutions for Mild Cases

• Use a slow feeder or puzzle feeder for fast eaters

• Feed smaller, more frequent meals

• Ensure fresh water is always available

• Brush regularly to reduce hairballs

• Transition food gradually (over 7–10 days) — see our Feeding Guide
