What is Feline Hyperthyroidism?
Feline Hyperthyroidism is a disorder that occurs when the feline thyroid gland produces an excess of thyroid hormone. An excess of thyroid hormone affects all of the cat's organ systems.
Hyperthyroidism occurs in middle aged and senior cats. Both feline sexes and all breeds are equally at risk.
The thyroid gland is butterfly-shaped and is located in the neck region of the cat. Hyperthyroidism is caused by a tumor in this gland. Ninety eight percent of these tumors are benign (adenoma) and two percent are cancerous (carcinoma). Seventy percent of cats have both lobes affected.
Symptoms of Feline Hyperthyroidism may include:
changes in behavior - anxiety or nervousness
excessive appetite or decreased appetite
increased water intake
hyperactivity or lethargy
excessive shedding, hair loss (alopecia), poor coat condition
diarrhea or vomiting
cardiac symptoms - rapid heart rate, arrhythmia
Feline Hyperthyroidism is fatal if left untreated!
