Why is my cat vomiting?

Occasional vomiting can occur, but repeated vomiting is not simply “normal for cats.” Frequency, appetite, hydration, weight and what the vomit looks like all help determine urgency.

Quick answer

Repeated vomiting, inability to keep water down, blood, marked lethargy, abdominal pain or vomiting with loss of appetite deserves prompt veterinary evaluation.

Vomiting or regurgitation?

Vomiting is an active process often preceded by nausea, salivation or abdominal contractions. Regurgitation is typically more passive and may occur soon after eating. Video can help your veterinarian distinguish the two.

Common causes of vomiting in cats

Causes range from hair ingestion and dietary problems to parasites, foreign bodies, inflammatory gastrointestinal disease, pancreatitis, kidney disease, hyperthyroidism, toxins and other systemic illnesses.

Urgent signs: repeated vomiting in a short period, blood, severe lethargy, painful or distended abdomen, suspected string/foreign body, toxin exposure, collapse or inability to keep water down.

What will the veterinarian check?

Depending on history and examination, testing may include bloodwork, urinalysis, fecal testing, radiographs or ultrasound. Chronic vomiting often deserves investigation even when the cat seems otherwise well.
