Cat Feline Acromegaly Welfare

Acromegaly from pituitary tumors causes insulin-resistant diabetes in cats. Recognition and treatment improve welfare for affected cats significantly.

Key Facts

Feline acromegaly is caused by growth hormone-secreting pituitary tumors
The condition causes insulin-resistant diabetes that is extremely difficult to control with insulin alone
Clinical signs include large body size, broad facial features, and diabetes that resists treatment
Pituitary tumor irradiation effectively reduces growth hormone and resolves insulin resistance
Many cats with 'brittle diabetes' are actually acromegalic and respond to appropriate treatment

Welfare Considerations

Acromegaly welfare is a case where correct diagnosis transforms treatment success. Cats with acromegaly-related diabetes fail to respond adequately to insulin and are often euthanised as 'brittle diabetics' when the underlying pituitary tumor is treatable. Recognition of acromegaly as the diagnosis and access to radiotherapy enables dramatically better welfare outcomes.

What You Can Do

Discuss acromegaly testing with your vet for diabetic cats with poor insulin response
Seek referral to a specialist if your cat's diabetes cannot be controlled with insulin
Support veterinary oncology programs developing accessible radiotherapy for feline pituitary tumors
Advocate for acromegaly screening as part of workup for all cats with newly diagnosed diabetes
