Vomiting is common in all cats, but excessive throwing up is not normal. If your cat is throwing up excessively every few weeks, you should take them to a vet as soon as possible. However, if this is your cat’s first time, you can try different methods at home to bring your pet back to normal.

Cats throw up for many reasons, such as food allergies, diabetes, irritable bowel disease, cancer, or kidney disorders. Vomiting might also be your cat’s reaction to eating something wrong. If you just found your cat throwing up, you are at the right place. This guide includes six crucial tips to develop your next action plan. So, let’s dive in.

Vomiting vs. Regurgitation

It’s essential to understand how vomiting differs from regurgitation before finding the treatment for your cat’s condition. Many cat owners also mistake vomiting for coughing, but all these three conditions are quite different.

Vomiting is when the content in your cat’s stomach and small intestine comes through their mouth. It begins with severe contraction of the cat’s abdominal muscles, requiring the animal to apply force to eject the vomit.

On the other hand, regurgitation doesn’t involve any type of force or abdominal contractions. Instead, it is a passive motion that expels the contents from the cat’s mouth and stomach. Regurgitation typically occurs when your cat has just finished eating or drinking, indicating an issue with the animal’s esophagus.

Coughing involves force, but nothing comes out of your cat’s mouth. It may look like your cat is vomiting by crouching down on their legs and stretching their neck. Sometimes, froth or foam may fill your cat’s mouth, but they usually swallow it again.

If you can’t understand the difference between vomiting, coughing, and regurgitation, you might record a video of your cat’s vomit and show it to your vet. Doing so will help diagnose your pet’s condition.

What Makes Your Cat Throw Up?

Cats can throw up whether or not they’re sick. They may throw up right after eating too fast or too much. They may also vomit in response to a change in their environment.

Cats with long hair are also likely to engulf hairballs that stick in their stomach, which they might end up throwing up. It’s normal if your cat vomits a hairball every one or two weeks. Doing so helps them prevent blockages from their digestive passage.

Remember, ejecting hairballs is not painful for your cat, but you should brush their fur regularly to keep it maintained. Some other common causes that make your cat vomit include the following:

  • Cancer
  • Diabetes
  • Hyperthyroidism
  • Kidney Disease
  • Food allergies
  • Food poisoning
  • Intestinal parasites
  • Inflammatory Bowel Disease
  • Foreign objects stuck in their digestive tract

These symptoms can cause a severe life threat to your pet, but early intervention can help them live a long, healthy life.

The 6 Important Tips to Treat Vomiting in Cats

Preventing the reasons for vomiting will be more comfortable for your cat than receiving the treatment. Thus, you must identify things that trigger vomiting in your cat and remove them from your cat’s surroundings.

Here are six effective tips to prevent and treat excessive vomiting in your cat:

1. Is hair involved?

Hairballs are the common cause of vomiting in cats, especially those with long hair. If this is the reason behind your cat’s illness, you can try switching to over-the-counter (OTC) hairball formulae upon your vet’s prescription.

These products prevent hairball formation by breaking it into smaller pieces through special enzymes. As a result, your cat does not throw up frequently. A high-fiber diet is also recommended for cats that vomit hairballs. Only give products to your cat after consulting a professional vet.

2. Evaluate Your Cat’s Diet

If your cat throws up, you should go through its diet and see what went wrong. Eating too many table scraps or treats can make your cat vomit at any time. Thus, modify your cat’s daily diet and monitor the quantity you give them. Always provide them with smaller portions multiple times a day.

You should always give your pet high-quality cat products and include nutritious foods in their diet. That’s the only way to keep your cat healthy in the long run.

3. Remove Objects That Are Not Edible

Your work isn’t done even if your cat has returned to their normal condition. Instead, you should look around and find non-food objects that your cat may swallow and vomit later. Cats are naturally curious, which is why they often get into accidents that make them sick.

You should remove toys, yarn, medicine, toxic plants, chocolate, and other tiny objects that your cat can ingest quickly. These objects can lead to digestive complications in your feline friend.

4. Inquire About a Special Cat Diet From Your Vet

If this is the third or fourth time your cat has vomited, you should take it to a vet to diagnose any underlying health issue. Food allergies, poisoning, and inflammatory bowel diseases are two common causes of frequent vomiting in cats.

If your doctor diagnoses any of these conditions in your cat, they prescribe you a special diet to avoid vomiting again.

5. Test for Acute Vomiting

You should immediately take your cat to a hospital for emergency treatment when its condition doesn’t seem to improve. The doctor will identify whether your cat has chronic vomiting or acute vomiting.

In acute vomiting, cats rarely throw up. To identify this condition, the veterinarian will perform the following tests:

  • A CBC blood test will show the symptoms of common diseases, such as diabetes or kidney diseases
  • A fecal test to detect parasites
  • Abdominal radiographs to identify large tumors or foreign objects

If these tests are negative, your cat is diagnosed with acute vomiting. The vet will prescribe you anti-nausea supplements for treatment.

6. Seek Medical Attention for Chronic Vomiting

Chronic vomiting is when your cat frequently vomits for months or once a week. Your vet will perform the below tests to diagnose this condition in your pet and determine the best treatment:

  • Gastrointestinal Panel. It will test your cat’s pancreas enzymes to diagnose pancreatitis. The doctor will also observe the folate and cobalamin to detect malabsorption in your pet’s small intestine.
  • The vet will test your cat’s abdomen to detect foreign objects in the pancreas. Ultrasounds will also help the doctor major the gastrointestinal tract’s wall and identify enlarged lymph nodes in case of cancer.
  • X-rays. Chest X-rays are necessary for older cats to identify the signs of cancer. This test helps the vet determine whether your cat has vomited, regurgitated, or coughed.

After performing these tests, your vet can differentiate between gastrointestinal lymphoma, food hypersensitivity, and inflammatory bowel disease. They may also recommend a new diet before performing these tests if your cat’s condition is related to food poisoning.


When Should You Call the Vet if Your Cat Vomits?

It is not necessary to contact a vet right after your cat throws up. That is because occasional vomiting is often not serious, and your cat will start feeling better after some time. However, there are some conditions in which you should call the vet right away. These include the following:

  • Your cat throws up more than three times consecutively.
  • The cat stops eating or drinking for 12 hours and has thrown up multiple times.
  • Your pet shows diarrhea symptoms after some time of vomiting. Cats need to stay hydrated in case of diarrhea, but you should never do anything without consulting your vet.
  • Your cat has a history of health issues, such as hyperthyroidism, diabetes, and kidney diseases. You should know that it is an emergency if your cat throws up with these health conditions. Early medical treatment can prevent your cat’s condition from getting worse.
  • You found worms in your cat’s vomit. After returning from the vet, you should deworm your entire home and the cat. You must also empty the cat’s litter box and ensure they live in a clean environment.

Occasional vomiting is common in all cat breeds, but excessive throwing up is not. If your cat has just thrown up, you should calm them down and remove all non-food items from their surroundings.

You can also feed them about 25% of their regular food after waiting for some hours. Wait for some time and see if your cat digested it properly. Then, increase their meal gradually over the next day.

However, if your feline vomits again, you will need a professional vet’s help to diagnose your pet’s underlying health issues. The vet will develop the best treatment plan to ensure your cat’s optimal health.
