2. Stomach Upsets (Gastritis) .
An inflammation of the cat’s stomach lining is simply referred to as gastritis. This condition may be mild or severe, but regardless of its type, make sure you bring your cat to visit the vet if it doesn’t show improvement in a day or two, or if the symptoms are severe.
Gastritis has many causes, from eating spoiled food to eating too fast to allergies or bacterial infections. If your cat is vomiting, belching, has a lack of appetite or bloodstained poop or diarrhea, a visit to the vet will help straighten things out. Treatments depend on the cause, but generally include medication, fluid therapy and even antibiotics.
