by beaconpet

If you notice your feline friend vomiting frequently, it is important to understand the different causes behind this worrying behavior. From hairballs to food allergies, inflammatory bowel disease to chronic kidney disease, there are many factors that can come into play. To make an accurate diagnosis and find the best treatment option, a thorough veterinary examination is essential. Treatment may include medication, dietary changes, surgery, or increased fluid intake. To prevent further episodes of illness, Beaconpet notes it is important to take preventative measures such as feeding smaller meals regularly, using automatic feeders, carefully reading ingredient lists, and Control pets in your home. By taking these steps and keeping toxic substances out of your cat’s reach, you can help minimize the frequency of vomiting and ensure your furry friend lives a happier, healthier life.



Hairballs are a common cause of frequent vomiting in cats. Cats groom themselves by licking their fur, and during this process, they ingest loose hairs. Normally, these hairs can pass through the digestive system without causing any issues. However, when a large amount of hair accumulates in the stomach and forms a compact mass, it can lead to the formation of hairballs.

Signs and symptoms of hairballs include hacking or retching sounds, frequent vomiting, coughing, reduced appetite, and constipation. The presence of hairballs in the vomit or feces may also be observed. If a hairball becomes lodged in the cat’s gastrointestinal tract, it can cause a blockage, which requires immediate medical attention.

Treatment options for hairballs include regular brushing to remove loose fur, feeding a specialized hairball control diet, and using hairball remedies such as hairball lubricants or gels. These substances help the hair pass through the digestive system more easily. In severe cases, surgical removal of a hairball may be necessary.

Food Allergies

Food allergies are another potential cause of frequent vomiting in cats. Common food allergens for cats include beef, fish, dairy products, and grains. When a cat ingests a food to which it is allergic, the immune system reacts by releasing histamines, which can lead to inflammation and gastrointestinal symptoms.

Signs and symptoms of food allergies include frequent vomiting, diarrhea, flatulence, bloating, itching or excessive grooming, and skin problems such as rashes or hair loss. In some cases, food allergies can also cause respiratory symptoms like sneezing or coughing.

Diagnostic tests for food allergies may involve an elimination diet, where certain ingredients are removed from the cat’s diet to determine the specific allergen. If the symptoms improve during the elimination diet and worsen when the suspected allergen is reintroduced, a food allergy can be confirmed.

Treatment options for food allergies involve identifying and avoiding the allergen. This often requires feeding a hypoallergenic or limited ingredient diet. In some cases, medications such as antihistamines or corticosteroids may be prescribed to alleviate symptoms.


Poisoning is a potentially life-threatening cause of frequent vomiting in cats. There are various substances that can be toxic to cats, including certain plants, chemicals, medications, and human foods. Cats are curious animals and may ingest something harmful without their owner’s knowledge.

Signs and symptoms of poisoning can vary depending on the toxic substance involved. Common signs include vomiting, diarrhea, drooling, muscle tremors, seizures, difficulty breathing, and changes in behavior or consciousness. It is important to note that not all toxic substances will cause immediate vomiting, and some may have delayed onset symptoms.

If you suspect that your cat has been poisoned, it is crucial to seek immediate veterinary assistance. While on the way to the vet, you can contact a pet poison control hotline for advice on what steps to take based on the specific toxin involved.

Treatment options for poisoning depend on the toxin ingested. In some cases, inducing vomiting or administering activated charcoal may be necessary to prevent further absorption of the toxin. Cats may also require supportive care such as intravenous fluids, medications to control symptoms, and in severe cases, antidotes.

Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic condition that causes inflammation in the lining of the cat’s gastrointestinal tract. The exact cause of IBD is unknown, but it is thought to be related to an abnormal immune response to the cat’s own intestinal bacteria or certain dietary components.

Signs and symptoms of inflammatory bowel disease can include chronic vomiting, diarrhea, weight loss, decreased appetite, and abdominal pain. Cats with IBD may also have a poor coat condition and may show signs of discomfort or distress during or after eating.

Diagnostic tests for inflammatory bowel disease may include blood tests, fecal exams, imaging studies, and an endoscopic biopsy of the intestinal tissue. These tests help to confirm the diagnosis and rule out other potential causes of vomiting.

Treatment options for inflammatory bowel disease may involve dietary changes, such as feeding a hypoallergenic or novel protein diet. Medications to control inflammation and modulate the immune system, such as corticosteroids or immunosuppressants, may also be prescribed. In some cases, antibiotics or probiotics may be used to restore a healthy balance of intestinal bacteria.



Pancreatitis is the inflammation of the pancreas, an organ that produces enzymes necessary for digestion. The exact cause of pancreatitis in cats is often unknown, but it can be related to factors such as obesity, dietary indiscretion, infections, or certain medications.

Signs and symptoms of pancreatitis can vary but commonly include frequent vomiting, diarrhea, loss of appetite, abdominal pain, and lethargy. Cats with pancreatitis may also exhibit dehydration, jaundice, or abnormal behavior.

Diagnostic tests for pancreatitis may involve blood tests to measure pancreatic enzymes and assess organ function. Imaging studies, such as ultrasound or X-rays, may also be used to evaluate the pancreas for inflammation or other abnormalities.

Treatment options for pancreatitis may include supportive care, such as intravenous fluids to maintain hydration and nutrition, and medications to manage pain and control vomiting. In severe cases, hospitalization may be necessary for more intensive management.

Chronic Kidney Disease

Chronic kidney disease (CKD) is a progressive condition that affects the functioning of the kidneys. It can be caused by factors such as aging, genetic predisposition, infections, or underlying conditions like high blood pressure or diabetes.

Signs and symptoms of chronic kidney disease can include frequent vomiting, increased thirst and urination, weight loss, decreased appetite, lethargy, and changes in the appearance or smell of urine. Cats with CKD may also experience electrolyte imbalances or high blood pressure.

Diagnostic tests for chronic kidney disease may involve blood tests to measure kidney function and assess other organ systems. Urinalysis may also be performed to evaluate kidney health. In some cases, imaging studies such as ultrasound or X-rays may be used to assess the size or structure of the kidneys.

Treatment options for chronic kidney disease aim to slow the progression of the disease and manage the associated symptoms. This may involve dietary changes, such as feeding a low-protein or kidney-supportive diet. Medications to manage high blood pressure or control symptoms like vomiting or nausea may also be prescribed. In some cases, fluid therapy or other supportive treatments may be necessary.


Diabetes is a condition in which the cat’s body is unable to properly regulate blood sugar levels. It can be caused by factors such as obesity, genetics, or underlying conditions that affect insulin production or function.

Signs and symptoms of diabetes can include frequent vomiting, increased thirst and urination, weight loss, increased appetite, lethargy, and changes in behavior or grooming habits. Cats with diabetes may also develop urinary tract infections or other complications.

Diagnostic tests for diabetes may involve blood tests to measure blood glucose levels and evaluate organ function. A urine sample may also be analyzed to check for the presence of glucose or ketones.

Treatment options for diabetes often involve insulin therapy to regulate blood sugar levels. This may require regular injections given by the owner. Dietary changes, such as feeding a low-carbohydrate or high-fiber diet, may also be recommended. Monitoring blood glucose levels at home and regular veterinary check-ups are important for the management of diabetes.


Hyperthyroidism is a condition in which the cat’s thyroid gland produces an excessive amount of thyroid hormone. It is typically caused by a benign tumor on the thyroid gland and is more commonly seen in older cats.

Signs and symptoms of hyperthyroidism can include frequent vomiting, weight loss despite an increased appetite, increased thirst and urination, restlessness or hyperactivity, rapid heart rate, and changes in behavior or appearance.

Diagnostic tests for hyperthyroidism may involve blood tests to measure thyroid hormone levels and assess organ function. Additional imaging studies such as ultrasound or scintigraphy may be used to evaluate the size or activity of the thyroid gland.

Treatment options for hyperthyroidism include medication to suppress the production of thyroid hormone, such as methimazole, or surgical removal of the thyroid gland. In some cases, radioactive iodine therapy may be recommended to target and destroy the abnormal thyroid tissue. Regular monitoring of thyroid hormone levels is necessary to ensure proper management.

Other Possible Causes

There are several other potential causes of frequent vomiting in cats that may require further investigation and management.

Gastrointestinal obstruction can occur when a foreign object or abnormal mass blocks the cat’s digestive tract. Signs and symptoms include persistent vomiting, abdominal pain, restlessness, and lack of appetite. Immediate veterinary attention is necessary to remove the obstruction surgically.

Liver disease can cause vomiting, along with other symptoms such as jaundice, weight loss, and changes in bowel movements or behavior. Diagnostic tests may involve blood tests to assess liver function and imaging studies to evaluate the liver’s structure.

Infections, such as viral or bacterial gastroenteritis, can cause vomiting in cats. Other signs may include diarrhea, fever, lethargy, or loss of appetite. Treatment options may involve antibiotics or supportive care to manage symptoms.

Cancer, particularly gastrointestinal tumors, can cause frequent vomiting in cats. Signs and symptoms may include weight loss, changes in appetite, lethargy, or the presence of abnormal masses. Treatment options for cancer may vary depending on the type and stage of the disease.

Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or certain antibiotics, can cause gastrointestinal side effects in cats, including vomiting. If your cat is taking any medications, consult with your veterinarian about potential side effects and alternative options if necessary.

Preventive Measures

Preventive Measures

While addressing the specific causes of frequent vomiting in cats is important, implementing preventive measures can help decrease the frequency and severity of vomiting episodes.

Feeding frequent small meals can help reduce the likelihood of overeating and minimize the strain on the cat’s digestive system. Using automatic feeders can also help regulate meal times and portion sizes.

Reading ingredient lists carefully when selecting cat food can help identify potential allergens or ingredients that may trigger sensitivities. Opting for high-quality, balanced diets can support overall digestive health.

Pet-proofing the home is essential to prevent cats from accessing toxic substances or ingesting foreign objects that could lead to vomiting or other health issues. This includes keeping cleaning products, medications, and toxic plants out of reach.

Regularly brushing the cat can help prevent the formation of hairballs by removing loose fur from the coat. This is particularly important for long-haired cats who are prone to hairball-related issues.

Keeping toxic substances away from the cat includes storing household chemicals or medications in secure locations, and being cautious about leaving human foods within reach. Common human foods that can be toxic to cats include chocolate, onions, garlic, and caffeine.

In summary, frequent vomiting in cats can be caused by a wide range of factors, including hairballs, food allergies, poisoning, inflammatory bowel disease, pancreatitis, chronic kidney disease, diabetes, hyperthyroidism, and more. A thorough veterinary examination is necessary to accurately diagnose and determine the best treatment options for frequent vomiting in cats. Treatment depends on the underlying cause and may involve medication, dietary changes, surgery, and increased fluid intake. Implementing preventive measures such as feeding frequent small meals, using automatic feeders, reading ingredient lists carefully, pet-proofing the home, brushing the cat to prevent hairballs, and keeping toxic substances away from the cat can help decrease the frequency and severity of vomiting episodes.
