Q. Best food for an underweight senior cat?
A. Any senior diet will help, but, if your cat has not had senior blood work in the past six months, it's a great idea to have this done. Underweight senior cats are often hyperthyroid, 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. Hyperthyroidism is easily treatable with medication and regular monitoring to make sure the medication is getting the thyroid levels into the correct range.
