What is Gum Disease in Cats

Gum disease, also known as periodontal disease, is a common condition in cats. It's primarily caused by bacterial plaque buildup, leading to more severe types of inflammation (Gingivitis) and/or the destruction of the tissues and bone that support the teeth, leading to tooth mobility and eventual loss (Periodontitis).    

Several factors can cause gum disease in cats:  

• Congenital factors  

• Diet and lack of oral hygiene  

• Infectious diseases - e.g. feline immunodeficiency virus or feline leukaemia virus
