Why Does My Cat Keep Throwing Up? Causes, Solutions & Prevention

Is your cat throwing up frequently? If so, you’re not alone. Many cat owners find themselves asking, “Why does my cat keep throwing up?” or “Why is my cat throwing up so often?” Occasional cat vomiting may not be a cause for concern, but frequent episodes require attention. According to a study by the American Veterinary Medical Association (AVMA), about 35% of feline vet visits are related to digestive issues, including vomiting.

Vomiting in cats can be caused by a variety of factors, including diet, allergies, hairballs, infections, or even underlying medical conditions. While a single episode may not be alarming, consistent vomiting should never be ignored. In this detailed guide, we will break down the causes of vomiting in cats, provide effective solutions, and offer preventive measures to ensure your cat stays healthy and happy.

Common Causes of Cat Vomiting

1. Hairballs (Trichobezoars)

Cats are natural groomers, and in doing so, they ingest a significant amount of fur. This fur accumulates in their stomach and can form hairballs. When these hairballs become too large to pass through the digestive system, the cat expels them through vomiting. While an occasional hairball is normal, frequent hairball vomiting can indicate excessive grooming or a digestive issue that prevents proper hair elimination.

Cause	Symptoms	Solutions
Excessive grooming	Frequent hairball vomiting, constipation	Brush your cat daily, use hairball control food
Low fiber diet	Hard stool, vomiting	Increase fiber intake through special cat food
Digestive inefficiency	Lethargy, loss of appetite	Consult a vet for digestive enzyme supplements

Key Tip: To prevent excessive hairballs, consider giving your cat a hairball prevention treat or adding a teaspoon of pumpkin to their diet to improve digestion.

2. Eating Too Fast

Some cats gobble down their food too quickly, leading to regurgitation shortly after eating. This occurs because the stomach expands too fast, triggering a reflux response. Fast eating can be a learned behavior, especially in multi-cat households where competition over food may be a factor.

Cause	Symptoms	Solutions
Competitive eating	Vomiting whole food, bloating	Use a slow feeder bowl, feed cats separately
Food texture	Regurgitation of kibble pieces	Soften dry food with water or switch to wet food
Overeating	Vomiting right after meals	Serve smaller, frequent meals

Key Tip: If your cat continues to eat quickly, try placing a large, clean stone or a ping-pong ball in their food dish to slow them down.

3. Food Allergies or Intolerances

Food allergies or intolerances occur when a cat’s immune system reacts negatively to certain proteins or ingredients in their diet. The most common allergens include dairy, beef, fish, and artificial additives. Symptoms may include vomiting, diarrhea, and skin irritations.

Common Allergens	Symptoms	Solutions
Dairy	Vomiting, diarrhea	Remove dairy from diet
Grains	Itchy skin, inflammation	Use grain-free food
Artificial additives	Lethargy, digestive upset	Choose natural, high-quality food

Key Tip: If you suspect a food allergy, switch your cat to a limited-ingredient diet and introduce new foods gradually.

4. Poisoning or Toxins

Cats are naturally curious, which often leads them to ingest harmful substances. Household items, plants, and certain foods can be toxic to felines, causing severe vomiting.

Toxic Substance	Symptoms	Emergency Response
Lilies	Severe vomiting, kidney failure	Immediate vet visit
Human medication	Drooling, lethargy	Call poison control
Chocolate	Diarrhea, seizures	Induce vomiting under vet supervision

Key Tip: Always keep harmful substances out of reach and educate yourself on what is toxic to cats.

5. Gastrointestinal (GI) Disorders

Chronic vomiting can be a sign of an underlying GI disorder, such as inflammatory bowel disease (IBD), pancreatitis, or gastroenteritis. These conditions require professional diagnosis and long-term management.

Condition	Symptoms	Treatment
IBD	Chronic vomiting, weight loss	Prescription diet, steroids
Pancreatitis	Lethargy, stomach pain	Hospitalization, IV fluids
Gastroenteritis	Diarrhea, dehydration	Antibiotics, hydration support

Key Tip: If your cat is vomiting persistently, seek veterinary care immediately to rule out serious conditions.

Preventing Cat Vomiting

1. Choose the Right Diet

A well-balanced diet tailored to your cat’s age and health needs can prevent many digestive issues. Look for high-quality protein sources and avoid fillers or artificial additives.

2. Maintain a Stress-Free Environment

Stress can trigger vomiting in cats. Provide a safe, quiet space for your cat to eat and rest without disturbances.

3. Regular Vet Checkups

Routine checkups can help catch health issues early, preventing severe conditions that may cause vomiting.

4. Use Digestive Supplements

Probiotics and digestive enzymes can help improve gut health and reduce vomiting episodes.

Conclusion

Vomiting in cats is a common issue, but it should never be ignored, especially if it happens frequently. Understanding the underlying causes, such as hairballs, food allergies, toxins, or gastrointestinal disorders, is key to providing the right treatment and prevention. By making dietary adjustments, slowing down their eating habits, and ensuring a stress-free environment, you can significantly reduce vomiting episodes. If vomiting persists, always consult a veterinarian to rule out serious health conditions.

Pro Tip:

If your cat frequently vomits, try elevating their food bowl to a comfortable height. This can improve digestion and reduce regurgitation!
