The vets at the Animal Hospital of Dauphin County have been evaluating a new cat food that is the first clinically proven diet to treat a medical condition. We’re very excited about the results. The new food was designed, researched and tested by the Hill’s Pet Food company for more than 10 years. It is used to treat feline hyperthyroidism, a condition in which the thyroid gland produces too much thyroid hormone. The thyroid gland is considered the “regulator” of the body. It determines how quickly the body uses energy, digests food, and makes proteins for other parts of the body to use. When a cat has hyperthyroidism, they can drink more water, urinate more, vocalize/meow more and have a big appetite despite losing weight. If you suspect your cat may have this condition our veterinarians can run blood tests to measure the amount of thyroid hormone produced in the body. There are four ways to treat hyperthyroidism: surgery to remove the thyroid gland, an injection of radioactive iodine which stops the overactive thyroid gland from producing too much hormone, a medication which suppresses the production of too much hormone and — now — the new Hill’s diet, called Hill’s Prescription Diet y/d. Hill’s y/d contains low iodine levels which “starves” the thyroid of its building block (iodine) which it uses to make thyroid hormone. It is clinically proven to lower the thyroid hormone level in as little as three weeks. Newly diagnosed cats can be started on the food and cats received anti-thyroid medications can be transitioned to the new diet. Even cats with normal thyroid function can eat it! The “normal” cats just need 1 tablespoon of regular cat food daily. Above is a picture of Cleo, one of the first patients at AHDC to be placed on Hill’s y/d. Her thyroid level went from 11.9 to 3.5 in 8 weeks. She loves the y/d and is doing great! If your cat has been diagnosed with hyperthyroidism, call us to discuss the option of Hill’s y/d diet!
