Hyperthyroidism in Cats: Causes, Symptoms, and Treatment
What Causes Hyperthyroidism in Cats?
Benign Tumor
In most cases of hyperthyroidism, the culprit is a benign tumor called an adenoma.
Diet
Interestingly, some fish-flavored wet foods (canned) have been linked to the development of hyperthyroidism in cats.
Age
Hyperthyroidism occurs often in cats, but there isn’t a genetic predisposition for the condition. In most cases, hyperthyroidism occurs during middle age and older kitties. On average, cats receive this diagnosis around age 13.
PBDEs
Flame-retardant chemicals, also known as PBDEs, may be present in your home furnishings. These chemicals go airborne and get circulated throughout your home and have been linked to the development of hyperthyroidism in cats.
