Transition Instructions

A gradual transition to a new pet food is important to avoid digestive upset. To transition, mix your pet’s current food with the new food. Over 7 days, gradually decrease the amount of the current pet food while increasing the amount of new pet food. In some cases, your veterinarian may recommend no transition or a shorter transition time.

Can I use a veterinarian's authorization if it was written by a veterinarian out of state? Yes. We accept valid authorizations from anywhere in the United States, Canada, and U.S. territories such as Puerto Rico.

Why do I need a veterinarian's authorization?

Because these diets are formulated for medical issues, veterinary authorization is needed to advise you on the best way to give them to your pet and to monitor your pet's health while they are on the diet.

Can someone else (such as a caretaker or family member) place an order for my pet?

Yes, but we'll need them to contact us and provide the full name of the pet's owner after the order is placed. This is so the veterinary clinic can locate your pet's records when we contact them. Email us at vetdiet@chewy.com or call us 24/7 at 1-800-672-4399.

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

Groundbreaking Nutrition for Thyroid Health

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

The Taste Factor

You might know that Hill's Prescription Diet is good for your pet, but she's only concerned with the taste.
