If the cat has chronic gastroenteritis, it can drink a small amount of yogurt appropriately. If the cat has acute gastroenteritis, it is best not to drink yogurt. Chronic gastroenteritis in cats is due to low gastric acid and pepsin secretion, which makes the intestines and stomach prone to indigestion. Drinking some yogurt can promote gastrointestinal motility. Cats with acute gastroenteritis need to fast and drink nothing, otherwise it will increase the burden on the gastrointestinal tract and aggravate symptoms such as vomiting.
