If your cat is nearing middle or old age, keep an eye out for signs of hyperthyroidism, a common disease of older cats. Thyroid glands in the neck normally produce hormones to drive the body’s engine, or metabolism. But enlarged glands produce too much of a good thing. Excessive thyroid hormone levels can overwork the heart as well as increase the blood pressure, which can injure the eyes, kidneys, heart and brain.
Suggestive signs in your cat include an increased appetite along with weight loss, excessive drinking and urinating, hyperactivity, vomiting, diarrhea or a poor hair coat.
If you have suspicions, it’s time to schedule an appointment with your veterinarian who will examine your cat and perform tests. Treatment options can then be discussed in order to cool your kitty’s revved-up engine.
