Cats vomit for many reasons. Sometimes it’s harmless, like coughing up a hairball. Other times, it can signal serious health problems. Occasional vomiting may not be a cause for concern, but frequent or sudden vomiting might require immediate attention.
In this guide, we’ll explore the most common causes of cat vomiting, including hairballs, food sensitivities, and illnesses. We’ll also cover remedies, prevention tips, and when it’s time to call the vet. By the end, you’ll know how to keep your cat healthy and happy.
What Causes Cat Vomiting?
Cats vomit for various reasons, ranging from simple digestive issues to serious illnesses. Understanding the causes can help prevent long-term health problems.
Hairballs – The Most Common Cause
Cats clean themselves by licking their fur, which leads to swallowing loose hairs. These hairs can clump together and form hairballs, which cats expel through vomiting.
Hairballs are usually harmless, but frequent vomiting of hairballs may indicate digestive issues or over-grooming caused by stress. Cats with long fur are more likely to develop hairballs, especially if they aren’t groomed regularly.
Remedies for Hairballs:
- Brush your cat regularly to remove loose fur.
- Feed specialized hairball-control cat food.
- Use hairball gels or treats to help the fur pass through the stomach naturally.
| Type of Vomiting | Signs | Action Needed |
|---|---|---|
| Normal Hairball Vomit | Occurs 1–2 times a month. | Monitor and increase brushing. |
| Frequent Vomiting | More than once a week. | Try hairball gel or special food. |
| No Hair in Vomit | Vomiting but no hair is visible. | Contact a vet for further tests. |
Eating Too Fast or Too Much
Cats that eat quickly may swallow air, leading to regurgitation soon after meals. Eating large portions can also stretch the stomach, causing vomiting.
Tips to Prevent Overeating:
- Serve smaller, more frequent meals instead of one large portion.
- Use slow-feeder bowls to force slower eating.
- Maintain a regular feeding schedule to avoid hunger-related binge eating.
Food Allergies and Sensitivities
Food allergies are a common cause of vomiting in cats. Ingredients like chicken, beef, and dairy are often allergens. Cats may also react poorly to artificial preservatives or fillers in low-quality cat food.
Symptoms of Food Sensitivities:
- Vomiting shortly after eating.
- Skin rashes or excessive itching.
- Loose stools or diarrhea.
Solutions:
- Switch to hypoallergenic or limited-ingredient cat food.
- Avoid giving your cat human food or table scraps.
- Transition to new diets slowly to reduce stomach upset.
Gastroenteritis and Upset Stomachs
Gastroenteritis, an inflammation of the stomach and intestines, can lead to vomiting, diarrhea, and loss of appetite. It may be caused by infections, spoiled food, or sudden dietary changes. Stress and environmental changes can also trigger stomach problems.
Mild cases can be treated at home by fasting your cat for 12 hours, offering small amounts of water, and feeding plain boiled chicken or rice for a day. If symptoms persist, your vet may need to perform blood tests or prescribe medications to treat infections or parasites.
Serious Health Problems
Vomiting can sometimes signal serious illnesses like kidney disease, diabetes, or hyperthyroidism. Older cats are especially prone to these conditions.
Common Health Issues That Cause Vomiting:
- Kidney Disease: Symptoms include vomiting, bad breath, weight loss, and increased thirst.
- Diabetes: Look for vomiting, excessive thirst, and weight changes.
- Hyperthyroidism: This condition speeds up metabolism, causing vomiting, weight loss, and hyperactivity.
| Illness | Symptoms | Treatment Options |
|---|---|---|
| Kidney Disease | Vomiting, weight loss, bad breath | Fluids, special diet, medications. |
| Diabetes | Vomiting, thirst, weight changes | Insulin, low-carb diet, vet checkups. |
| Hyperthyroidism | Vomiting, weight loss, hunger | Medication, surgery, or iodine therapy. |
Diagnosis and Treatment:
Your vet may recommend blood tests, ultrasounds, or X-rays to diagnose these problems. Treatments might include medications, special diets, or ongoing monitoring.
When to Worry About Cat Vomiting?
Most cats vomit occasionally, but certain signs mean you should contact a vet immediately.
Emergency Symptoms to Watch For:
- Vomiting several times in one day.
- Blood or foam in the vomit.
- Weakness, hiding, or refusing food.
- Sudden weight loss or bloating.
These symptoms could point to poisoning, blockages, or internal diseases that need urgent care.
How to Treat Cat Vomiting at Home
Safe Remedies for Mild Vomiting
If your cat vomits occasionally but seems otherwise healthy, you can try simple home treatments.
- Fasting for 12 hours gives the stomach time to settle.
- Offer water in small amounts to prevent dehydration.
- Feed bland foods, like boiled chicken or plain rice, after fasting.
- Return to regular meals slowly.
Remedies for Hairballs:
Brushing reduces loose fur and prevents hair buildup. Special diets and gels can also help hairballs pass through the digestive system without vomiting.
Managing Food Sensitivities:
Switch to a limited-ingredient diet and introduce new foods gradually to avoid reactions.
Preventing Cat Vomiting in the Future
Prevention is easier than treatment. Regular care can lower the risk of vomiting.
Tips for Preventing Vomiting:
- Brush your cat daily to reduce hairballs.
- Feed smaller, more frequent meals to slow down eating.
- Use slow-feeder bowls to prevent overeating.
- Provide fresh water to keep your cat hydrated.
- Schedule regular vet visits for health monitoring.
Older cats may need softer foods or diets designed for sensitive stomachs. Regular care and attention can help prevent many causes of vomiting.
When Should Senior Cats Get Extra Care?
Senior cats are more likely to suffer from chronic illnesses that cause vomiting. Kidney problems, arthritis medications, and dental issues are common concerns.
Soft foods and special diets for older cats can reduce stomach stress. Regular checkups allow vets to monitor your cat’s health and catch problems early.
