So, let’s embark on this journey together and shed light on the enigma of why your cat may be throwing up food while acting completely normal.

What to do if your cat is throwing up food 

Vomiting, also called throwing up, is the emptying of a cat’s stomach contents. Cats vomit for many different reasons. Some of the causes of vomiting are extremely serious, and others are less worrisome.

The first thing you should do if your cat is throwing up food but acting normal is to observe your cat closely. How often is your cat vomiting? Is it just once or twice, or more frequently? What does the vomit look like? Does it contain food, hairballs, blood, bile, or foreign objects? Is your cat showing any other signs of illness, such as lethargy, loss of appetite, weight loss, diarrhea, or dehydration?

If your cat is vomiting only occasionally and seems otherwise healthy, it may not be a cause for concern. However, if your cat is vomiting more than once or twice a month, or if the vomit contains blood, bile, or foreign objects, you should take your cat to the vet as soon as possible. These could be signs of a serious medical problem that needs immediate attention.

Common Causes of Vomiting in Cats

There are various reasons why a cat might be vomiting up food but acting utterly normal after that. There is no need to panic in most cases, especially if there aren’t any other notable symptoms. But, if throwing up is followed by loss of appetite, lethargy, weight loss, then you should be alarmed.

Let’s find out more about what causes vomiting and how you should deal with it.


One of the most common causes of vomiting in cats is hairballs. Cats groom themselves by licking their fur, which results in swallowing some of the loose hair. Most of this hair passes through the digestive system without any problem, but sometimes it accumulates in the stomach and forms a ball that can’t be digested.

When this happens, the cat tries to expel the hairball by coughing or vomiting. This is usually not a serious issue, unless the hairball is too large or too frequent and causes an obstruction or inflammation in the stomach or intestines.

According to Animalpath.org, hairballs are more common in long-haired cats, such as Persians or Maine Coons, and in cats that shed excessively or groom themselves more often than usual.

To prevent hairballs, you can brush your cat regularly to remove the loose hair and use hairball remedies that can help lubricate the digestive tract and facilitate the passage of hair. You can also feed your cat a special diet that is designed to reduce hairball formation.

Eating Too Fast or Too Much

If there’s something that cats are guilty of, it is being obsessed with food. Our felines love a good meal! However, sometimes they love it so much that they decide to gobble it down in a matter of seconds. This is the situation when you see all the food that they just ate all over your floor.

Since the feline didn’t even have time to process this food, the act is not called vomiting – it’s regurgitation. That’s how fast everything happens!

Felines have an esophagus that is positioned horizontally and not vertically. So, when they eat too fast, it’s pretty easy for the food to come back up.

Eating too fast is very common in households with multiple cats. As you probably already know by now, felines are very competitive. When you give them food, one or more of the cats will get competitive and they’ll start eating with the speed of light.

Another reason why cats might eat too fast or too much is boredom or stress. If your cat doesn’t have enough stimulation or enrichment in their environment, they might turn to food as a source of comfort or entertainment.

Eating too fast or too much can cause not only vomiting but also indigestion, bloating, gas, diarrhea, obesity, and diabetes. Therefore, it’s important to control your cat’s eating habits and make sure they don’t overeat or gulp down their food.

To slow down your cat’s eating pace, you can use slow feeders, puzzle toys, or elevated bowls that make them work for their food and prevent them from swallowing large chunks at once. You can also feed your cat small and frequent meals throughout the day instead of one large portion.

Food Allergies or Intolerance

Did you know that cats can get allergies? Just like humans, cats can be allergic to things, including certain foods. Allergies don’t necessarily have to appear when the cat is born either, and your feline can develop them at any age. This is one of the main reasons why owners are caught by surprise when their adult cat that loved chicken and ate it regularly starts being allergic to it.

If your cat is throwing up but seems otherwise fine, then you can suspect allergies. This could also be a reason why your cat has diarrhea but seems fine. Other potential symptoms include respiratory issues, itching red skin, hair loss, and weight loss.

Food allergies are different from food intolerance, which is a digestive problem that occurs when the cat can’t properly digest or absorb a certain ingredient in the food. Food intolerance can also cause vomiting, diarrhea, gas, and abdominal pain.

Some of the most common food allergens or intolerances in cats are chicken, beef, dairy, eggs, fish, wheat, corn, and soy. However, any food can potentially cause a reaction in your cat, depending on their individual sensitivity.

If you think that your feline is suffering from allergies or intolerance and you notice any of these symptoms, call your vet. They will do tests to figure out what causes the sensitivity and how to treat it. Usually, the treatment involves eliminating the offending food from the cat’s diet and replacing it with a hypoallergenic or novel protein diet that doesn’t contain any ingredients that the cat has been exposed to before.

Eating Grass or Foreign Objects

Another reason why your cat might be throwing up food but acting normal is that they ate something that they shouldn’t have. Cats are curious creatures and they like to explore their surroundings with their mouth. Sometimes, they might ingest grass, plants, toys, strings, bones, or other objects that can irritate their stomach or cause an obstruction in their digestive tract.

Some cats eat grass on purpose because it helps them induce vomiting and get rid of hairballs or other indigestible materials. Grass also contains folic acid, which is an essential vitamin for cats. However, not all grasses are safe for cats and some might contain pesticides or parasites that can harm them.

Other cats eat foreign objects accidentally or intentionally because they have a condition called pica, which is an abnormal appetite for non-food items. Pica can be caused by nutritional deficiencies, medical problems, behavioral issues, or boredom.

Eating grass or foreign objects can cause not only vomiting but also choking, perforation, infection, inflammation, or blockage in the cat’s digestive system. Therefore, it’s important to keep your cat away from toxic plants, chemicals, or objects that they might ingest and provide them with safe and appropriate toys to play with.

If you suspect that your cat has eaten something that they shouldn’t have and they vomit more than once or show signs of distress, such as drooling, pawing at their mouth, gagging, difficulty breathing, or abdominal pain, take them to the vet immediately. They might need surgery to remove the foreign object from their stomach or intestines.

Stress or Anxiety

Cats are sensitive animals and they can get stressed or anxious by various factors in their environment. Some of the common stressors for cats are:

  • Moving to a new home
  • Introducing a new pet or person
  • Changing their routine or schedule
  • Loud noises or unfamiliar smells
  • Lack of attention or stimulation
  • Conflict or aggression with other cats
  • Separation from their owner

Stress or anxiety can affect your cat’s physical and mental health and cause various symptoms, such as:

  • Vomiting
  • Diarrhea
  • Loss of appetite
  • Weight loss
  • Urinary problems
  • Excessive grooming
  • Hiding
  • Aggression
  • Depression

To prevent and treat stress or anxiety in your cat, you need to identify the source of the problem and try to eliminate it or reduce its impact. You also need to provide your cat with a safe and comfortable environment where they can relax and feel secure.

Some of the things you can do to help your cat cope with stress or anxiety are:

  • Provide your cat with enough food, water, litter boxes, scratching posts, toys, and hiding places.
  • Maintain a consistent routine and schedule for your cat’s feeding, grooming, playing, and sleeping.
  • Avoid sudden changes in your cat’s environment or lifestyle.
  • Introduce new pets or people gradually and with positive associations.
  • Give your cat enough attention and affection but respect their boundaries and preferences.
  • Enrich your cat’s environment with interactive toys, puzzles, or games that stimulate their natural instincts and curiosity.
  • Use calming products such as pheromones, herbs, or supplements that can help reduce your cat’s stress levels.
  • Consult your vet if your cat’s stress or anxiety is severe or persistent. They might prescribe medication or behavioral therapy for your cat.

How to prevent or reduce cat vomiting with diet and lifestyle changes

There are some things you can do at home to prevent or reduce cat vomiting with diet and lifestyle changes. Here are some tips:

  • Consider your cat’s diet. Make sure your cat is eating a high-quality and balanced diet. That also applies to feeding too many treats or table scraps. Avoid sudden changes in the cat’s diet, as this can cause digestive upset. If your cat has food allergies or inflammatory bowel disease, you may need to switch to a hypoallergenic or prescription diet.
  • Watch for non-food items. Cats are curious creatures and may ingest things that are not meant for them. Keep potential foreign objects out of your cat’s reach, such as strings, rubber bands, coins, buttons, etc. If you suspect your cat has eaten something he shouldn’t have, contact your vet immediately.
  • Ensure they get enough water. One of the biggest causes of digestive issues is a lack of hydration. Make sure your cat has access to fresh and clean water at all times. You can also encourage your cat to drink more by providing multiple water bowls, adding water to their food, or using a fountain or dripping faucet.
  • Help them with hairballs. If your cat has frequent hairballs, you can help them by brushing them regularly to remove loose fur, feeding them a hairball control diet or supplement, or giving them a laxative or lubricant (such as petroleum jelly) to help them pass the hairballs more easily.
  • Arrange a visit to your vet. Even if your cat is not showing any signs of illness, it’s a good idea to have them checked by your vet at least once a year. Your vet can perform routine tests and screenings to detect any potential problems early and prevent them from getting worse.

Is it normal for cats to throw up occasionally?

Occasional vomiting in cats can be normal, especially if they have consumed something that doesn’t agree with their digestive system. However, frequent or persistent vomiting should not be considered normal and may indicate an underlying health problem that requires attention.

Can certain cat breeds be more prone to vomiting?

While there is no breed-specific predisposition to vomiting, some individual cats may be more prone to gastrointestinal issues or have sensitive stomachs. It’s important to monitor your cat’s overall health and behavior, regardless of breed, and address any vomiting concerns promptly.

Are there any home remedies to alleviate vomiting in cats?

While there are some home remedies that might help alleviate occasional vomiting in cats, it’s crucial to consult with a veterinarian before attempting any remedies. They can provide appropriate guidance based on the underlying cause of the vomiting. However, some general measures include feeding smaller meals, providing access to fresh water, and minimizing stressors in your cat’s environment.

Can overfeeding contribute to vomiting in cats?

Yes, overfeeding can contribute to vomiting in cats. Feeding large portions or allowing unlimited access to food can lead to overeating, which can overload the digestive system and result in vomiting. It’s important to follow portion guidelines provided by your veterinarian and establish a feeding routine that suits your cat’s needs.


In conclusion, if you find yourself wondering why your cat is throwing up food but acting normal, it’s essential to remember that occasional vomiting in cats can happen for various reasons. While it can be unsettling to witness, it doesn’t always indicate a severe health issue. However, it’s crucial to pay attention to the frequency, consistency, and accompanying symptoms of vomiting to determine if further action is needed.

Understanding your cat’s individual behavior and habits is key to deciphering the underlying cause of vomiting. Factors such as eating too quickly, hairballs, dietary indiscretions, food allergies, or stress can all play a role in this puzzling behavior. Monitoring your cat’s overall health, providing a balanced diet, promoting a stress-free environment, and seeking veterinary advice when necessary are crucial steps in ensuring your cat’s well-being.
