Feline diabetes

In cats, obesity is the most recognized risk factor for diabetes. 

Affected cats develop insulin resistance that, when the pancreatic beta cells eventually fail to compensate, results in persistent hyperglycemia. 

Almost 4x greater risk of diabetes than cats in ideal body condition.

Obesity causes insulin resistance in cats.2-4

Weight loss can help to decrease insulin resistance and reduce the risk for diabetes mellitus.2

Canine diabetes is typically more similar to type 1 diabetes in people. While obesity does not appear to be a direct risk factor, insulin resistance has been reported in overweight dogs5 and can make canine diabetes more difficult to manage.6

Key things to remember

  • Obesity is the most recognized risk factor for feline diabetes, and obese cats have an almost 4 times greater risk than cats in ideal body condition.
  • Weight loss can help to decrease insulin resistance and reduce the risk for diabetes mellitus.
