Cat throwing up is one of the most common reasons pet owners rush to emergency veterinary clinics, yet many cases don't actually require urgent care. Knowing when vomiting signals a true emergency can save your cat's life—and potentially save you unnecessary stress and expense.
Understanding what your cat's vomit looks like and what other symptoms accompany it helps you make better decisions about when to seek immediate help. Let's explore when cat vomiting requires emergency attention and when it can wait for a regular veterinary visit.
Top Questions About Cat Vomiting
When should I seek emergency care for my cat's vomiting?
Seek emergency care if your cat is throwing up blood, has multiple vomiting episodes within a few hours, or shows signs of low energy. Cats who have ingested known toxins like lilies, household cleaners, or human medications need quick veterinary attention. Persistent vomiting combined with inability to keep water down also warrants urgent care.
Call ahead to confirm the emergency clinic can see your cat right away. This helps the veterinary team prepare for your arrival.
What does the color of my cat's vomit mean?
Bright red blood in vomit indicates active bleeding and requires quick veterinary attention. Dark, coffee-ground-like material suggests digested blood, which is equally concerning. Yellow-green bile in repeated vomiting episodes may signal bile duct or liver issues.
Foamy vomit with undigested food could indicate regurgitation rather than true vomiting. White foam may appear when a cat has an empty stomach but continues to vomit.
How can I tell if my cat is too sick to wait for a regular vet appointment?
Multiple vomiting episodes in a day, blood in vomit, or extreme weakness are signs your cat needs emergency care. Cats unable to stand or who collapse when attempting to walk need help right away. Pale gums, rapid breathing, or a racing heart rate are signs your cat may be seriously ill.
Call a veterinary professional for guidance if you're unsure. They can help you decide whether your cat needs emergency care or can wait for a regular appointment.
Why Cats Throw Up
Cats can throw up for many reasons ranging from minor issues to serious medical conditions. Hairballs can happen in cats who groom frequently, especially long-haired breeds. Eating too quickly or sudden diet changes can upset a cat's sensitive digestive system.
More concerning causes include stomach blockages from swallowed objects, inflammatory bowel disease, kidney or liver problems, thyroid issues, or even cancer. Parasites, infections, and toxin exposure can also trigger vomiting episodes.
Spotting Mild Cases
A single vomiting episode followed by normal behavior typically doesn't require emergency care. Cats who throw up hairballs but continue eating, drinking, and acting normally are usually experiencing a common feline issue. Occasional vomiting (less than once weekly) without other symptoms may simply reflect a sensitive stomach.
Watch for continued interest in food and water, normal energy levels, and regular litter box use. These signs suggest your cat is likely not experiencing a medical emergency.
Recognizing Serious Cases
Multiple vomiting episodes within 24 hours signal a potentially serious problem. Cats throwing up blood or bile need quick veterinary attention. Vomiting accompanied by low energy, hiding, or refusing to eat or drink for more than 12 hours indicates your cat may be seriously ill.
Additional concerning signs include stomach pain (crying when touched, hunched posture), difficulty breathing, or fever. Cats with underlying health conditions like diabetes or kidney disease who begin vomiting should be seen right away, as their condition can worsen rapidly.
What To Do
Step 1: Assess your cat's symptoms
Note how often your cat is throwing up and what the vomit looks like. Check if there's blood, bile, or foreign material in the vomit. Watch for your cat's energy level, responsiveness, and whether they're showing signs of pain or stress.
Take a photo of the vomit if possible, as this can help veterinarians with diagnosis. Try to recall any recent changes in diet, new plants in the home, or potential access to toxins.
Step 2: Call a veterinary facility for guidance
Describe your cat's symptoms in detail, including when the vomiting started and any other unusual behaviors. Ask whether your cat's condition warrants an emergency visit or if it can wait for a regular appointment.
Be prepared to answer questions about your cat's medical history, current medications, and recent activities. This information helps the veterinary team assess the urgency of your cat's condition.
Step 3: Prepare your cat for transport
Place your cat in a secure carrier lined with a soft towel that can be easily cleaned if vomiting continues. Keep the environment quiet and calm to reduce stress, which can worsen vomiting. Avoid feeding your cat before transport unless specifically instructed by a veterinarian.
Bring any samples of vomit or suspected ingested materials to the appointment. This can provide valuable information for the veterinary team.
Potential Life-Threatening Conditions
Stomach blockages occur when cats swallow items like string, toys, or bones that become lodged in the digestive tract. These blockages prevent food and fluid from passing normally, causing repeated vomiting and severe pain.
Toxin ingestion from plants like lilies, household cleaners, or human medications can cause vomiting and lead to organ failure if not treated quickly. Severe stomach infections may cause inflammation and damage to the digestive tract lining. Inflammation of the pancreas triggers intense pain and vomiting that requires quick medical management.
Kidney or liver problems often present with vomiting as an early sign. These conditions can worsen rapidly without proper treatment.
Helping Your Pet Before the Vet Visit
Offer small sips of water
Provide just a teaspoon of water at a time to prevent triggering more vomiting. Excessive water consumption after vomiting can irritate the stomach and cause additional episodes. Call your veterinary clinic immediately for guidance on appropriate hydration methods for your cat's specific situation.
Ice cubes may be gentler than liquid water for some cats. Allow your cat to lick an ice cube to get small amounts of moisture without overwhelming their stomach.
Withhold food temporarily
Remove food for a short period during acute vomiting episodes to give your cat's stomach a chance to settle. Call your veterinary clinic immediately for instructions on when to resume feeding and what foods might be gentle on your cat's digestive system.
When reintroducing food, offer small amounts of bland options if recommended by your veterinarian. Watch your cat closely for additional vomiting after eating.
Preventing Future Vomiting
Maintain a consistent feeding routine
Feed your cat smaller meals throughout the day rather than one or two large meals. This helps prevent stomach distension and reduces the likelihood of vomiting. Stick to regular feeding times to establish digestive predictability.
Avoid sudden diet changes that can upset your cat's sensitive digestive system. When transitioning to new food, do so gradually over 7-10 days by mixing increasing amounts of new food with decreasing amounts of the old food.
Schedule regular checkups
Regular veterinary examinations help catch potential health issues before they cause chronic vomiting. Regular blood work can detect early signs of conditions that commonly cause vomiting in cats.
Discuss any recurring vomiting patterns with your veterinarian, even if they seem minor. What appears to be "normal" hairballs might actually indicate an underlying digestive issue that can be addressed with proper treatment.
