Vomiting
Is it a normal cat thing
If you’ve lived with cats for any length of time, you’ve probably heard that all-too-familiar sound. The hacking, gagging noise right before your cat throws up. Many cat parents assume that occasional vomiting is just a normal part of feline life. After all, don’t cats throw up hairballs all the time? The truth is, vomiting is not normal in cats, and frequent episodes should always be taken seriously. While the occasional hairball or upset stomach can happen, regular vomiting is often a sign that something more concerning is going on with your cat’s health.
Why Vomiting Isn’t Normal
Cats have sensitive digestive systems, but that doesn’t mean throwing up should be routine. Many people chalk it up to “just cats being cats,” but experts agree that vomiting is usually a symptom, not a quirk. Occasional vomiting from eating too fast or the occasional hairball can happen, but repeated episodes point to underlying issues.
Chronic vomiting can damage the esophagus, cause weight loss, and leave your cat dehydrated or nutrient-deficient. Just as with humans, frequent vomiting is your cat’s way of telling you something is off—and it shouldn’t be ignored.
How Much Vomiting Is Too Much?
One of the most common questions cat parents ask is: How often is too often? A cat that vomits once every few months after a hairball is usually fine. But if your cat vomits more than once or twice a month, it’s worth keeping an eye on. If it happens weekly or more, that’s a clear red flag and should be discussed with your veterinarian.
Keep in mind that even mild but frequent vomiting isn’t normal. For example, if your cat vomits small amounts of food or bile a few times a month, it’s still cause for concern. Tracking the frequency, timing, and what’s in the vomit can help your vet determine the underlying problem.
Common Causes of Vomiting in Cats
There are many reasons why a cat may vomit, ranging from simple to serious. Understanding the possibilities can help you decide when to seek veterinary attention.
​
1. Hairballs
Cats groom themselves constantly, and some swallowed fur is normal. Occasionally, this forms a hairball that your cat will vomit up. However, if your cat is bringing up hairballs more than once every few weeks, it could indicate excessive grooming, digestive motility issues, or another health condition.
​
2. Dietary Issues
Food sensitivities, allergies, or diets high in fillers and artificial ingredients can irritate a cat’s stomach. Sudden food changes or poor-quality diets can also trigger vomiting. Some cats simply eat too quickly, gulping air along with food, which then comes back up soon after meals.
​
3. Gastrointestinal Disorders
Chronic vomiting may point to inflammatory bowel disease (IBD), gastritis, or even gastrointestinal cancers. These conditions require veterinary diagnosis and often long-term management with special diets or medications.
4. Parasites
Intestinal worms, such as roundworms or hookworms, can cause vomiting, weight loss, and a poor coat condition. Regular deworming and fecal checks are crucial, especially for cats who go outdoors or hunt.
​
5. Toxins and Foreign Objects
Cats are curious by nature, and ingesting plants, chemicals, spoiled food, or non-food items can result in vomiting. Foreign objects like string, plastic, or toys can also block the digestive tract, leading to repeated vomiting and requiring immediate veterinary attention.
​
6. Systemic Illness
Diseases that affect other organs—such as kidney disease, liver disease, hyperthyroidism, or pancreatitis—can all cause vomiting as a secondary symptom. Regular blood-work at the vet can help catch these issues early.
7. Stress or Environmental Changes
Cats are sensitive to their surroundings, and stress can manifest in physical ways, including digestive upset. Moving, new pets, or changes in routine can sometimes trigger vomiting episodes.
​
When to See the Vet Immediately
Some vomiting is an emergency. Contact your veterinarian right away if your cat:
-
Vomits multiple times in one day
-
Brings up blood or a coffee-ground appearance
-
Has projectile vomiting
-
Shows signs of lethargy, dehydration, or refusal to eat
-
Has diarrhea alongside vomiting
-
Produces no stool or vomits unproductive retches (could signal a blockage)
​
Final Thoughts
While the occasional hairball or upset stomach may not be unusual, vomiting should never be considered normal for cats. If your cat vomits more than once or twice a month, it’s time to investigate further with your vet. Causes can range from minor diet issues to more serious medical conditions, but catching the problem early is the best way to protect your cat’s health.
​
Your cat can’t tell you what’s wrong—but their body will. By paying attention to vomiting patterns and seeking veterinary guidance when needed, you’ll help keep your feline friend comfortable, healthy, and thriving.
