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.

Save your fur-baby’s life!

This food, saved my cats life! I have an old cat (almost 22, now) but about a year ago, I found myself in tears because Miyagi was throwing up a lot, lost weight and looked like he only had days to live. Our vet put him on this diet and it was almost an immediate turnaround! Now, he’s more social than he has ever been and has the energy of an adult (not senior) cat. We do have to add water to each serving. Otherwise, it dries quickly and Miyagi has a hard time pooping. Only downfall is, we can’t get the shipments right since it’s not always in stock. At first, we didn’t get enough and now, we have a huge surplus. But, that’s just the norm with many items since the pandemic.

A big hit!

Janie absolutely love this new food! I've never seen her get so excited about eating. Both wet and dry are a hit with her. And it seems to agree well with her sensitive tummy! Hopefully her next blood work will show that it's helping her thyroid issues too, making it expensive but well worth the cost. Based on her weight she gets half a can of wet and 1/4 cup of dry a day. At first she was begging for more but has adjusted her expectations and is satisfied with this daily portion.

Improved my cats thyroid!!

I started my cat on this about 4 months ago because she is "pre-thyroid disease," (elevated thyroid values). We switched from Blue Buffalo, canned and dry. I was worried my cat would not like it, as she can be a little picky, but she loved it! I have ONLY fed her this food, no treats, etc. which was difficult for her but she loves the food. We got her bloodwork done again, and her thyroid values are lower than last time! Still on the high end but controlled. Seems like the diet is working :)

Amazing Results!!!

Our 18 year old cat had severe hyperthyroid. Her T4 levels were at 22. After one dose of medication she was a mess, could barely walk and could barely eat. After a few days, the meds were out of her system we started her on this food. In 3 weeks of eating the wet and dry food exclusively, her numbers are almost normal (4.4) She can't eat it fast enough!!!

Finnicky cat with a thyroid problem

After the cat refused to eat the wet food, we contacted Hill's. They suggested heating it in the microwave on the lowest temperature for 10 to 13 seconds. Make sure it is not too hot. It enhances the flavor. We also found if we add just a touch of water and chop it up then it is more like the flaked food in gravy that the cat is prefers.

Price increase Why did my price go up from $76.99?

Wonderful service and reliability. I have had no problems in all the years I have been receiving Chewy proscription food for my cat Thor.

Cat doesn't like

I need to preface this by saying my cat does not like pate. I have tried mixing it with a little warm water(which had been suggested) and try to make it into little bits. Still will not eat it.

Prescription for thyroid disease

My cat liked it okay at first, but now I have a hard time getting her to eat it. It's difficult because according to my vet that's all she supposed to eat

My cat is not crazy about can YD

I wish this came in a smaller size. Wet food is very dry. I have to add water to it for moisture, mush it like baby food & then heat for a few seconds. My cat is not a picky eater. He loves the dry, but can is not his favorite.

Great service

I needed to order a prescription cat food because the Vet couldn’t get it. I checked with Chewy they had it, sent it out and I received it the following day! That was a big relief because the food is my cats medication!
