Feline Diabetes


What are the signs of diabetes mellitus in cats?


Depending on how severely insulin production or utilization is impaired, the symptoms can range from subtle to obvious. The most common signs of diabetes are:


  • Increased thirst (polydipsia) and urination (polyuria)

  • Inappropriate elimination (urinating outside the litter box)

  • Change in appetite

  • Weight loss

  • Change in gait (walking)

  • Decreased activity, weakness, depression

  • Vomiting


How is diabetes diagnosed?


The diagnosis of diabetes mellitus in cats is based upon the presence of persistently high blood glucose levels (hyperglycemia) even when the animal had not eaten recently (fasted), concurrent glucose in the urine (glucosuria), and clinical signs. Clinical signs alone cannot be a basis for the diagnosis since hyperthyroidism and kidney disease, both very common diseases in older cats, can have similar signs. Your pet's doctor will use the history, physical examination findings, and laboratory results together to provide a diagnosis.


How is diabetes treated?


As in people, diabetes is more often managed with lifestyle changes than treated with a single treatment. The most common treatments include diet change and insulin or oral hypoglycemic agents. Treatment is tailored specifically to each individual's life style and needs.
