Gastritis is an inflammation or damage to the lining of the stomach. This can be the result of any of the following:

  • Infectious disease
  • Swallowing a foreign object (toy)
  • Food allergy
  • Dietary intolerance (lactose intolerance)
  • Eating spoiled food
  • Ingesting toxins or medications

If your cat does have gastritis take him/her to the vet immediately. Gastritis can be an indicator of a more serious problem and if left unchecked gastritis can lead to ulcers, chronic gastritis, and stomach disorders.

Symptoms to look for:

  • Vomiting
  • Blood in the vomit or stool
  • Gas
  • Belching
  • Decreased appetite
  • Decreased water intake
  • Diarrhea
  • Seizures
  • Restlessness
  • Irritability
  • Lethargy or restlessness
  • Weight loss


Your vet will examine your cat by taking blood or urine samples, and your cat may have an X-ray taken to see if there is gas or foreign objects in the stomach. Based on the cause of the gastritis your vet may prescribe any or all of the following 1) fluids to fight dehydration, 2) antibiotics, 3) anti-emetics for vomiting, and 4) pain relievers. Your vet may also ask you to limit food intake for 24-36 hours while the stomach gets back to normal.

Precautionary measures:

Keep your cat on a steady, healthy diet and avoid changing your cat’s diet. Also avoid over-stressing your cat. Try to keep all substances that could be toxic to your cat out of his/her reach. Also keep all food and water bowls clean and disinfected.
