Hyperthyroidism in cats is caused by an increase in production of thyroid hormones from enlarged thyroid glands, located on both sides in the cat's neck. In most cases, enlargement of the thyroid glands is caused by a tumor called an adenoma, which is almost always non-cancerous. The average age of cats with hyperthyroidism is 13 years of age; only about 5 percent of hyperthyroid cats are younger than 10 years of age.
Possible causes of hyperthyroidism include: 1  Iodine levels in cat food â either too low or too high. 2  PBDEs â PBDEs are fire retardant chemicals that can be found in high concentrations in some fish and also in house dust. 3  Soy in cat food â Soy is a known disruptor of thyroid gland function. If you have read my Feeding Your Cat: Know the Basics of Feline Nutrition which outlines what it means to be an obligate carnivore, you will understand that soy has no logical place in cat food.
