Understanding Your Cat’s Vomiting: Causes, Concerns, and When to Seek Vet Care

Overview of Cat Vomiting

Vomiting in cats is a common but sometimes concerning issue. While an occasional upset stomach isn’t always cause for alarm, frequent or severe vomiting can signal an underlying health problem that requires veterinary attention. Understanding the difference can help you act quickly and ensure your cat stays healthy.

At Livingston Veterinary Hospital, we are committed to helping pet owners recognize, manage, and prevent vomiting in cats.

Common Causes of Vomiting in Cats

Dietary Causes

Cats can be sensitive eaters, and dietary issues are a leading cause of vomiting.

  • Eating too quickly – Some cats eat too fast, leading to regurgitation.
  • Dietary indiscretion – Consuming spoiled food, plants, or non-food items (like string or plastic) can upset the stomach.
  • Food allergies or intolerances – Some cats react poorly to certain ingredients, leading to chronic digestive issues.

A consistent, high-quality diet is key to preventing digestive problems. If your cat frequently vomits after eating, your veterinarian may recommend a diet change or elimination trial.

Hairballs: A Frequent Cause of Vomiting

Hairballs are a common cause of vomiting, especially in long-haired cats or those that groom excessively. While an occasional hairball is normal, frequent vomiting of hairballs may indicate an underlying gastrointestinal issue.

Prevention strategies include:

  • Brushing regularly to reduce hair ingestion
  • Hairball control diets that help hair move through the digestive system
  • Laxative-based supplements to assist in hair passage

Infections & Parasites

Viral, bacterial, or parasitic infections can cause vomiting, often accompanied by diarrhea, lethargy, or weight loss. Common culprits include:

  • Gastrointestinal infections (bacterial, viral, or fungal)
  • Roundworms, hookworms, or tapeworms

Routine fecal exams and deworming help prevent parasite-related vomiting.

Chronic Diseases That Can Cause Vomiting

Some long-term illnesses contribute to frequent or severe vomiting, including:

  • Chronic Kidney Disease (CKD) – Causes nausea, weight loss, and increased thirst.
  • Hyperthyroidism – Leads to excessive hunger, weight loss, and vomiting.
  • Diabetes – Can cause vomiting due to metabolic imbalances.

Early detection and proactive management can help your cat live a longer, healthier life.

What Does the Type of Vomit Indicate?

The appearance of vomit provides important clues about its cause:

  • Clear or foamy vomit – Gastric irritation or acid reflux.
  • Yellow or bile-stained vomit – May indicate prolonged fasting or liver/gallbladder issues.
    Undigested food – Eating too quickly, food intolerance, or possible obstruction.
  • Blood in vomit – Could signal ulcers, internal bleeding, or toxin ingestion.
