Cat Vomiting: Causes, Symptoms, Treatment & Home Remedies

Introduction

Seeing your little furball vomit on the floor, carpet, or bed can be really alarming. This can instantly raise concerns for pet parents. While occasional vomiting may happen due to hairballs or eating too fast, frequent or repeated episodes may indicate an underlying health concern that needs veterinary attention.

Studies suggest that digestive complaints, including cat vomiting, are among the common reasons cats are taken to veterinary clinics. Many pet owners often wonder, why do cats vomit even when they seem otherwise healthy. The answer can vary from mild stomach irritation to infections, food intolerance, parasites, or chronic medical conditions¹.

In this article, we will discuss the causes of cat vomiting, common symptoms, diagnosis, cat vomiting treatment options, supportive home care tips, and what to do when a cat vomits frequently.

What is Cat Vomiting?

Vomiting in cats refers to the forceful expulsion of stomach contents through the mouth. It usually involves abdominal contractions, nausea, and retching¹.

It is important to understand the difference between vomiting and regurgitation. Regurgitation usually happens without forceful abdominal movements and often involves undigested food returning soon after eating².

Common Types of Cat Vomiting

Cat vomiting may appear in different forms depending on the underlying cause, frequency, and the material being expelled. Understanding the different types of vomiting helps to reach an accurate diagnosis.

• Acute Vomiting: This starts suddenly and may last for a short period. It may happen due to dietary changes, spoiled food, or minor digestive irritation¹.
• Chronic Vomiting: Vomiting that continues for several days or occurs repeatedly over weeks may require medical evaluation¹.
• Hairball Vomiting: Cats swallow loose hair while grooming, which may form hairballs and trigger vomiting³.
• Food Vomiting: Presence of undigested food in vomit usually indicates the cat vomited shortly after eating³.
• White Foam Vomiting: White foamy vomit contains stomach fluids and mucus and may occur when the stomach is empty³.

Causes of Cat Vomiting

There can be several causes of cat vomiting, ranging from mild digestive upset to more serious illnesses. Common causes may include³:

• Sudden Diet Change: Rapid changes in diet may cause stomach upset and vomiting.
• Overeating or Eating Too Fast: Eating large amounts or eating quickly can trigger vomiting.
• Toxic Ingestion: Consumption of toxic substances, harmful plants, or unsafe human foods can cause vomiting.
• Foreign Body Obstruction: Swallowing objects may block the digestive tract and induce vomiting.
• Infectious Diseases: Viral, bacterial, or parasitic infections may result in vomiting.
• Food Intolerance or Allergy: Sensitivity to certain food ingredients may lead to vomiting.
• Inflammatory Bowel Disease (IBD): Inflammation of the digestive tract can cause recurrent vomiting.
• Obstruction in the urinary tract: The cat’s urinary tract is blocked, and it is unable to pass urine.
• Systemic Diseases: Disorders affecting the liver, kidneys, or pancreas may lead to vomiting.
• Toxin Exposure: Exposure to toxins can irritate the digestive system and trigger vomiting.
• Constipation or Large Bowel Disease: Digestive disorders affecting the bowel may contribute to vomiting.
• Cancer: Certain cancers may cause vomiting in cats.

Pet parents who frequently ask why do cats vomit should know that repeated vomiting is not considered normal and may need veterinary attention.

Symptoms of Cat Vomiting

The symptoms associated with cat vomiting may vary depending on the underlying cause. Common signs may include³:

• Restlessness and Agitation: Cats may appear uneasy or uncomfortable before vomiting.
• Excessive Swallowing and Lip Licking: Frequent swallowing, lip licking, and increased salivation can occur before vomiting.
• Abdominal Contractions: Strong stomach and abdominal movements are commonly seen during vomiting.
• Fatigue After Vomiting: Cats may appear tired or distressed after vomiting due to the effort involved.

Persistent symptoms should not be overlooked, particularly in kittens, old cats, or those with pre-existing health conditions.

Diagnosis of Cat Vomiting

Veterinarians may diagnose the cause of vomiting through:

• Physical examination: The vet may check the cat for physical parameters such as weight, temperature, abdominal discomfort; signs of dehydration and any other signs that may be linked to the cat’s vomiting⁴.
• Blood tests: These help assess hydration levels, infection markers, and other internal changes that may have led to vomiting⁴.
• X-rays or ultrasound: Imaging techniques help identify inflammation, blockages, or structural abnormalities in the abdomen⁴.
• Endoscopy: This procedure allows the veterinarian to examine the inside of the stomach using an endoscope, a flexible tube fitted with a camera. In some cases, it can help identify the cause of vomiting directly, while in others, it may be used to collect small tissue samples (biopsies) for microscopic examination to detect underlying disease⁵.
• Laparoscopy: This is a minimally invasive technique used when a blockage or obstruction in the gastrointestinal tract is suspected or biopsies are needed. It allows the veterinarian to examine and operate on the abdominal organs and may help identify the cause of vomiting⁶.
• Urine analysis: This helps analyse the pH level and the presence of red blood cells, white blood cells, bacteria, or protein in the urine⁷.

The veterinarian may also ask how often the cat is vomiting, what the vomit looks like, and whether there are any other associated symptoms. Proper diagnosis is important because many conditions may have similar symptoms.

Treatment of Cat Vomiting

The approach to cat vomiting treatment may depend on the underlying cause, the severity of symptoms, and the cat’s overall condition. Care for your sick cat may include supportive measures such as⁴:

• Medicines to Control Vomiting: Antiemetic drugs may be prescribed to control vomiting, reduce fluid loss, and relieve abdominal discomfort.
• Stomach Protectants: Medications such as stomach protectants may be prescribed to help reduce stomach irritation in some cases.
• Pain Management: Pain-relieving medications may be prescribed if vomiting is associated with abdominal pain.
• Prednisone Therapy: Prednisone may be used in cases of inflammatory bowel disease (IBD), but only under veterinary supervision due to its possible side effects.

In severe cases, hospitalisation and advanced supportive care may be necessary. Pet parents should avoid giving human medications to cats without professional guidance, as some medicines may be unsafe.

Home Remedies for Cat Vomiting

Certain supportive home remedies for cat vomiting may help in mild cases. However, these measures are not substitutes for veterinary care if symptoms continue or worsen³.

• Slow Feeding Methods: Using puzzle feeders or slow feeder bowls can help cats eat more slowly, improving digestion and reducing vomiting after meals.
• Sensitive Stomach Diets: Switching to specially formulated cat food for sensitive stomachs may help reduce vomiting, preferably under veterinary guidance.
• Regular Grooming: Daily brushing helps reduce loose hair ingestion and minimises hairball-related vomiting.
• Providing Cat Grass: Allowing cats access to fresh grass may support digestion and provide beneficial nutrients, which can help some cats with occasional vomiting.

Further studies are needed to establish the effects of supportive home remedies for cat vomiting on feline digestive health.

How to Stop Cat Vomiting?

Pet parents often search for how to stop cat vomiting safely. Based on the underlying cause of vomiting, helpful measures may include⁴:

• Fluid Therapy: Fluids may be given under the skin or intravenously to prevent dehydration and maintain hydration caused by vomiting.
• Dietary Changes: Easily digestible or prescription diets may be recommended to reduce stomach irritation and identify food intolerance or allergies.
• Limited-Ingredient Diets: Cats with chronic vomiting may benefit from special diets designed for dietary sensitivities.

If vomiting occurs frequently or is associated with other symptoms, professional evaluation is recommended.

When to See a Veterinarian?

Seek veterinary attention if your cat³:

• Has repeated or severe vomiting.
• Cannot retain food or water.
• Has lethargy, diarrhea, weight loss, or appetite changes along with vomiting.
• Has worms in the vomit (may indicate a parasite infection).
• Cat is not passing urine (the urinary tract may be blocked).

Pet parents wondering what to do when cat vomits repeatedly should avoid delaying veterinary consultation, especially in kittens and elderly cats.

Conclusion

Cat vomiting can occur due to several reasons, such as hairballs, digestive upset, infections, dietary issues, or chronic health conditions. While occasional vomiting may sometimes occur in otherwise healthy cats, repeated or persistent vomiting should not be overlooked.

Understanding the causes of cat vomiting, recognising warning signs early, and seeking timely veterinary guidance may help support better outcomes and overall wellbeing of your cat.

If vomiting persists or your cat develops additional symptoms, consulting a qualified veterinarian is the safest approach.
