Hiatal Hernia in Cats
 
A hernia occurs when one part of the body protrudes through a gap or opening into another part of the body. For example, a hiatal hernia takes place at the opening of the diaphragm where the food pipe joins the stomach. Part of the stomach pushes through the opening, and a hernia is formed. It is most likely to occur before a kitten has reached the first year, and is usually inherited (congenital). However, trauma may bring on an acquired hiatal hernia, and this can occur at any age.
