A. A voracious appetite coupled with weight loss or no weight gain can be a sign of diabetes or hyperthyroidism. Many older cats have hyperthyroidism, where the thyroid gland produces too much hormone and causes the cat's metabolism to run much higher than normal. This puts extra strain on the heart and kidneys and causes weight loss, even if the cat is still eating well. I recommend getting your cat in to see your vet for an exam and labwork. Hyperthyroidism is easily treatable with medication and regular monitoring to make sure the medication is getting the thyroid levels into the correct range.
