ResumoThis chapter describes the pathogenesis, clinical signs, diagnosis, and treatment of diabetes mellitus in dogs and cats. Dogs are susceptible to insulin-dependent diabetes mellitus or absolute insulin deficiency as a result of genetic predisposition to immune-mediated islet destruction or as a result of exocrine pancreatic disease. It is commonly thought that most cats develop type 2 diabetes mellitus characterized by obesity, insulin resistance, and pancreatic amyloid deposition. Dogs present with polydipsia, polyuria, and cataract formation; however, the diagnosis of early type 2 diabetes in cats can be challenging. Diagnosis in dogs is made on the basis of fasting hyperglycemia and glucosuria; however, cats are susceptible to stress hyperglycemia and have a higher renal threshold for glucose, therefore glycated blood proteins are often used to diagnose diabetes in cats. Dogs require insulin therapy to prevent development of ketoacidosis. Cats, on the other hand, can often be managed with diet and insulin, diet and oral hypoglycemic therapy, or diet alone.
