What Causes Cat Vomiting?

It can be concerning to see your cat vomiting, especially if it happens frequently or without an obvious cause. Occasional vomiting may not be a reason to worry, but persistent or severe episodes can indicate an underlying issue. Cats vomit for various reasons, ranging from minor dietary indiscretions to more serious health conditions. If your cat is vomiting and you’re unsure why, it’s always best to consult your veterinarian. At Sahara Pines Animal Hospital in Las Vegas, NV, our team can assess your cat’s health and provide the appropriate care. Call (702) 876-7580 or book an appointment online today.

What Are Some Common Causes of Cat Vomiting?

Hairballs and Grooming Habits

Cats are known for their meticulous grooming, which often results in hair ingestion. When a cat grooms itself, loose fur is swallowed and can accumulate in the stomach, forming a hairball. If the hairball is too large to pass through the digestive tract, your cat may vomit it up. While occasional hairballs are normal, frequent vomiting due to hairballs could indicate an issue such as excessive grooming or gastrointestinal sensitivity.

To help minimize hairballs, regular brushing can reduce the amount of loose fur your cat ingests. Additionally, hairball-control diets and treats may aid digestion. However, if your cat vomits frequently and no hairballs are present, other causes should be considered.

Dietary Indiscretions and Food Sensitivities

Sudden changes in diet or eating something unusual can lead to cat vomiting. Some cats have sensitive stomachs and may not tolerate certain ingredients, especially artificial additives, dairy, or rich foods. Overeating or eating too quickly can also cause vomiting, as can ingesting spoiled food or items that should not be eaten.

If your cat vomits shortly after eating, consider offering smaller, more frequent meals. A slow-feeder bowl can help prevent gulping, which may reduce vomiting. If you suspect a food allergy or intolerance, speak with a veterinarian about an elimination diet to identify problematic ingredients.

Gastrointestinal Issues and Infections

Underlying gastrointestinal problems can contribute to cat vomiting. Conditions such as inflammatory bowel disease (IBD), gastritis, or food allergies can lead to chronic vomiting and digestive upset. Bacterial or viral infections, such as feline panleukopenia, may also cause vomiting along with other symptoms like diarrhea and lethargy. If vomiting is persistent and accompanied by weight loss, diarrhea, or a change in appetite, a veterinary evaluation is necessary. Diagnostic tests may be required to determine if an infection or gastrointestinal disorder is present.

More Serious Causes of Cat Vomiting

Toxins and Foreign Objects

Cats are curious animals and may ingest toxic substances or foreign objects, both of which can result in vomiting. Common toxins include household cleaners, human medications, certain plants (such as lilies), and chemicals like antifreeze. Additionally, ingesting string, rubber bands, or small objects can lead to an obstruction in the digestive tract. If you suspect your cat has ingested something harmful, seek immediate veterinary care. Symptoms of toxin ingestion or obstruction include vomiting, lethargy, drooling, and difficulty defecating.

Organ Disease and Chronic Illness

Vomiting can sometimes indicate an underlying chronic disease affecting the kidneys, liver, or pancreas. Conditions such as kidney disease, hyperthyroidism, and pancreatitis can cause nausea and vomiting over time. Older cats are more prone to these issues, so regular veterinary check-ups are essential for early detection. Bloodwork and other diagnostic tests can help determine if organ dysfunction is contributing to vomiting. Managing these conditions with your veterinarian’s guidance can improve your cat’s quality of life and reduce digestive distress.

Parasites and Worm Infestations

Intestinal parasites, including roundworms, hookworms, and tapeworms, can cause vomiting in cats. Kittens and outdoor cats are particularly at risk, as parasites are commonly transmitted through contaminated soil, infected prey, or flea infestations. Signs of a parasite infestation may include vomiting, diarrhea, a bloated abdomen, and visible worms in the stool or vomit. Routine deworming and parasite prevention treatments can help protect your cat from these issues. If you suspect parasites, a fecal test at your veterinarian’s office can confirm their presence.

When to Contact Your Veterinarian

While occasional vomiting may not be alarming, frequent or severe episodes should not be ignored. Contact your veterinarian if your cat:

• Vomits multiple times in a day or for more than 24 hours
• Shows signs of lethargy, dehydration, or weakness
• Has blood in the vomit or stool
• Experiences weight loss or appetite changes
• Exhibits signs of pain, such as vocalizing or hiding

If your cat is vomiting, identifying the cause is the first step toward finding relief. Observing their eating habits, monitoring for additional symptoms, and seeking veterinary guidance can make a significant difference. Sahara Pines Animal Hospital in Las Vegas, NV, is here to help.
