Cats are smaller animals than humans. Which would you expect to have a (relatively speaking) more active thyroid glan

A final conclusion is not possible from this information

Explanation:

In mammals, the thyroid is an endocrine gland composed of two lobes that are connected by a bridge of tissue referred to as thyroid isthmus. The thyroid gland produces different types of hormones including calcitonin, triiodothyronine and thyroxine. These hormones are known to increase basal metabolism and thus affect metabolic-associated mechanisms including appetite, nutrient absorption and gut motility. However, thyroid hormones are not directly associated with the growth rate. It is important to note that the growth hormones are synthesized by the pituitary gland.
