Hill's Prescription Diet y/d Thyroid Care for Cats


Groundbreaking Nutrition for Thyroid Health
Hill's breakthrough formula was designed to help felines with hyperthyroidism thrive. Cats with this disorder have an overactive thyroid gland—meaning it produces too much of the thyroid hormone—but limiting iodine in your cat's food can help regulate it. Prescription Diet y/d does that and more, all in a tasty kibble your cat will love. You may even see a difference in as little as three weeks.
Clinical Nutrition
With Hill's, it's not just high-quality ingredients that count. Their focus is on the proper balance of nutrients in every recipe. So, Hill's designed food to help pets with health conditions, providing the right nutrients to support their health. Hill's alliance with veterinarians puts them in a position to find a nutrition recommendation for your pet, no matter what health issue your pet is facing.


Formulated by Veterinarians
Hill's Prescription Diet started with a veterinarian's belief that some health issues could be managed through nutrition. What began as a theory has now been proven through extensive research by a team of over 220 vets, PhD nutritionists and food scientists. The results can be seen in Hill's Prescription Diet therapeutic pet foods.
Meeting the Highest Standards
Providing a food that delivers exactly what it says it does is Hill's number one priority. In fact, they perform over five million safety and quality checks every year. They've established relationships with trusted suppliers and will only accept ingredients that meet stringent standards.


The Taste Factor
You might know that Hill's Prescription Diet is good for your pet, but she's only concerned with the taste. Even though they place a heavy emphasis on nutrition, Hill's hasn't forgotten about palatability. Savory ingredients are combined to produce foods with enticing aromas, textures, and shapes that your pet can't resist.
