The Signs of Hyperthyroidism

Sometimes the sight of an older, skinny cat is thought to be “normal.” However, some cats might have a disease process that is causing them to look thin and frail with a rough haircoat – perhaps Hyperthyroidism?

Hyperthyroidism is an endocrine disease of the thyroid gland causing it to produce too much thyroid enzyme. The clinical signs that an owner recognizes are:

· Vomiting

· Weight loss

· Rough, unkept haircoat

· Voracious appetite

· Change in behavior-hyperactive – seeking extra attention

· Increased thirst

Hyperthyroidism is diagnosed by doing bloodwork, and it is a treatable disease. There are various options for treatment that should be discussed with a veterinarian. After treatment is initiated, clients are pleasantly surprised when their cat starts to gain weight and has a “normal appetite” again.
