Why is my cat's stomach gurgling? Causes, when to worry, and what to do

A cat's stomach noises (borborygmi) are often harmless — hunger or digestion — but can signal illness when paired with vomiting, diarrhea, pain or lethargy. Learn causes, red flags, and when to see a vet.

Introduction

If your cat's belly is making audible gurgling or rumbling noises you might be alarmed. Those sounds — called borborygmi — can be completely normal, but they can also be an early clue that the gastrointestinal (GI) tract is irritated, inflamed, obstructed, or infected.

This guide explains when stomach gurgling is harmless, common causes ranked by likelihood, what other symptoms change the urgency, safe home care steps, and clear guidance on when to contact your veterinarian or seek emergency care.

Primary source: Merck Veterinary Manual and veterinary emergency guidance are used throughout (see citations at the end).

What are normal vs abnormal GI sounds?

• Normal: Occasional soft gurgling or rumbling, especially when a cat is hungry, after a meal as gas and liquids move through the gut, or in very thin cats where sounds transmit more easily. These are brief, not associated with other signs, and the cat behaves normally.
• Abnormal: Loud, continuous, or frequent gurgling combined with other signs — vomiting, diarrhea, lethargy, abdominal pain, poor appetite, weight loss, fever, or changes in drinking/urination. Abnormal sounds may reflect increased intestinal motility, inflammation, partial obstruction, or infection.

When stomach gurgling is usually not urgent

• Your cat is bright, alert, grooming normally, eating and drinking as usual, and has normal litterbox habits.
• Gurgling occurs around mealtime or right after eating, and resolves within 24–48 hours.
• No vomiting, no diarrhea, no signs of pain.

When gurgling becomes concerning — urgent vs emergency

Decision support: use the following to decide how fast to act.

Urgent (see your veterinarian within 24 hours):

• Repeated vomiting (more than once or ongoing)
• Diarrhea lasting >24 hours or producing blood or large volumes
• Reduced appetite for >24 hours or noticeable drop in energy
• Signs of dehydration (sunken eyes, tacky gums, reduced skin elasticity)
• Weight loss, persistent abdominal discomfort, or changes in urination

• Continuous retching with little to no production of vomit
• Distended, painful abdomen or signs of severe abdominal pain
• Collapse, severe lethargy, or unresponsiveness
• Difficulty breathing, pale gums, or rapid heart rate
• Visible blood in vomit or stool, or inability to pass stool
• Suspected toxin ingestion or swallowing of foreign object/linear material

When to See a Vet Immediately

If your cat has stomach gurgling plus any of the emergency signs above, take them to an emergency veterinary clinic immediately. Some causes that present this way (intestinal obstruction, severe pancreatitis, sepsis, toxin exposure) can become life-threatening quickly and require diagnostics and supportive care that cannot be provided at home.

What your vet will likely do

• Physical exam and hydration assessment
• Bloodwork (CBC, chemistry, electrolytes), urinalysis
• Fecal testing for parasites and pathogens
• Abdominal X‑rays and/or ultrasound to look for obstruction, masses, or inflammation
• Specific testing for pancreatitis or metabolic disease if indicated
• IV fluids, antiemetics, pain control, and targeted therapy depending on diagnosis

Home care steps (safe, conservative measures)

Do these only if your cat is stable (bright, drinking, not repeatedly vomiting) and you have ruled out emergency signs.

• Monitor: Keep a close log of appetite, water intake, vomiting episodes, diarrhea, and any changes in behavior.
• Hydration: Encourage access to fresh water. If your cat is drinking less, contact your vet — dehydration can be dangerous in cats.
• Food: Offer small, frequent bland meals (a tiny amount of boiled chicken or a prescribed gastrointestinal diet) rather than withholding food long-term. Important: Do not fast adult cats for more than 24 hours without veterinary advice — prolonged anorexia can precipitate hepatic lipidosis.
• Grooming: Brush long-haired cats to reduce hairball formation.
• Remove hazards: Keep potential toxins and string/linear objects out of reach.
• Do NOT give human medications (Pepto-Bismol, acetaminophen, ibuprofen) or over-the-counter antidiarrheals without veterinary approval.

Red Flags — Seek Emergency Care

• Repeated or forceful vomiting, especially if unable to keep water down
• Severe abdominal pain, distension, or sensitivity to touch
• Blood in vomit or stool (bright red or black/tarry)
• Rapid breathing, collapse, or seizures
• Signs of shock: pale gums, cold extremities, very weak or unresponsive

Examples of common scenarios and what to do

• Scenario A: Cat gurgles before breakfast, eats normally, plays and uses the litterbox — action: watchful waiting, normal.
• Scenario B: Cat gurgles then has one episode of soft stool and eats a little less for a day — action: monitor closely, offer water and small meals; call vet if symptoms persist >24–48 hours.
• Scenario C: Cat gurgles, then repeatedly vomits and becomes lethargic — action: urgent vet visit or emergency clinic now.

Preventive measures

• Feed a consistent diet and avoid sudden food changes.
• Use slow-feeder bowls if your cat eats too quickly.
• Regular parasite prevention and fecal checks.
• Regular grooming to prevent hairballs.
• Keep small objects, strings, and potentially toxic foods/medications out of reach.

Key Takeaways

• Occasional stomach gurgling (borborygmi) is commonly normal, especially around mealtimes.
• Watch for accompanying signs: vomiting, diarrhea, loss of appetite, lethargy, abdominal pain — these raise concern.
• If your cat is bright, eating, drinking and behaving normally, monitor for 24–48 hours; if signs worsen or persist, contact your vet.
• Seek urgent veterinary care for repeated vomiting, dehydration, severe abdominal pain, bloody stool/vomit, collapse, or suspected toxin/obstruction.
• Never give human medications or attempt to treat serious conditions at home — diagnostics and treatment should be guided by a veterinarian.
