DIABETES MELLITUS IN CATS
Diabetes mellitus is a common condition in cats, and usually occurs when they are middle aged or older. It is
more common in neutered males but can occur in both sexes. If left untreated, complications develop which can
eventually be fatal.
The most common signs of diabetes mellitus are:
• Increase in urination and thirst
• Weight loss
• Increase in appetite
Less common signs include:
• Weakness in hind legs, reluctance to jump and/or walking in crouched position
• Dry, lusterless hair coat
• Urinary tract infections
• Vomiting, decreased appetite, depression (potentially an emergency)
Diabetes mellitus is caused because a hormone called insulin is no longer produced or is not effective. Insulin
enables sugar (glucose) in the blood to be taken up by body to then provide them with energy.
Diabetes is diagnosed by testing a blood and urine sample, and finding high glucose in both of these.
In cats it is relatively common for diabetes to occur secondarily to another condition or disease. Diabetes can be
a complication of obesity, certain drugs or other medical conditions. In these cases it may be reversible with
treatment of the underlying condition. Your vet may suggest further tests or treatment if this is suspected.
If you are concerned that your cat is displaying any of the above symptoms please contact the practice to
arrange an appointment.
