Cats
Repeated vomiting is not automatically a harmless hairball; string, lilies and urinary obstruction can be dangerous.
SYMPTOM → WHAT DO I DO?
Vomiting
Understand what happened, what to document, and when vomiting becomes urgent.
CALL YOUR VETERINARIAN PROMPTLY
READ THIS FIRST
Observations can help your veterinarian. They cannot rule out an emergency.
Contact an emergency veterinary facility immediately for difficult breathing, collapse, ongoing seizures, inability to urinate, major bleeding, abnormal gum color, sudden severe abdominal swelling or rapidly worsening weakness.
What could be behind this symptom?
These are possibilities, not a diagnosis. The right explanation depends on the examination, species and medical history.
- Dietary indiscretion or a sudden food change
- Parasites, infection, inflammation or pancreatitis
- Foreign material, intestinal blockage or toxic exposure
- Kidney, liver, endocrine or medication-related disease
What can you safely check at home?
Write down what you see and bring photographs or video only when doing so does not delay care.
- How many episodes occurred and whether food, foam, bile or blood appeared
- Whether the animal is trying to vomit but producing little or nothing
- Appetite, water intake, stool, energy and abdominal comfort
- Possible access to toys, string, bones, medications, plants or spoiled food
Avoid actions that can make things worse.
- Do not give human antacids, anti-nausea medications or pain relievers.
- Do not induce vomiting unless a veterinarian or animal poison professional directs you.
- Do not force food or water into an animal that is actively vomiting.
- Do not pull string hanging from the mouth or rectum.
When should you contact your veterinarian?
- Call the same day for repeated vomiting, continued nausea, reduced appetite or an animal that is very young, old or medically fragile.
- Discuss any new medication, chronic disease, recent diet change or possible foreign material.
- A single mild episode in an otherwise bright adult still deserves a call if it recurs or the animal changes.
Get emergency help immediately if you see:
- Repeated unproductive retching, a swollen abdomen or severe abdominal pain
- Blood, dark coffee-ground material, collapse, weakness or pale gums
- Suspected poison, swallowed object, inability to keep water down or breathing difficulty
The same symptom can mean different things in different animals.
Rabbits & small mammals
Rabbits cannot vomit. Gagging, choking, drooling or abdominal distension requires urgent rabbit-experienced care.
Birds
Distinguish behavioral regurgitation from forceful vomiting, head shaking or food on the face; illness can progress quickly.
Domestic equines
Horses, donkeys and mules generally cannot vomit; material from the nostrils, choking or abdominal pain is an emergency.
