Definition

• Glucose is the primary source of energy for a cat. When the cat's body is no longer able to regulate its glucose levels because of a lack of sufficient insulin, hyperglycemia (diabetes) develops.
  
  

Significance

• When a cat's glucose levels rise, a variety of symptoms will be present. Typically, cats will develop weight loss despite a ravenous appetite, along with increased drinking and increased urination.
  
  

Identification

• In cats, usually glucose is calculated in milligrams per deciliter. Healthy glucose levels in cats range between 80 and 120 mg/dL. Cats with levels as high as 400 to 600 mg/dL are considered diabetic.
  
  

Method

• A cat's blood glucose level should be periodically monitored through blood-glucose curves performed at the vet's hospital. Owners may also monitor glucose levels at home through various testing kits.
  
  

Considerations

• Glucose levels in cats may get high at times because of excitement or anxiety. This is called ''stress hyperglycemia'' and may be mistaken for diabetes.
  
  

Prognosis

• The goal for a cat with high glucose levels is to bring them down to an acceptable range of 100 to 300 mg/dL. This is accomplished through regulation with insulin injections.
