Feeding Instructions

Because iodine intake from other food sources (treats, another cats food, etc.) can compromise the effectiveness of low-iodine nutrition, its critical that you follow your veterinarians feeding instructions carefully and feed only y/d. Adjust feeding amounts as necessary to maintain optimal weight. If you are unsure, ask your veterinarian. For best results & safety practices: Gradually transition to your pets new food over a 7 day period. Exclusively feed the recommended Prescription Diet dry and/or canned food. Keep fresh water available at all times. Have your veterinarian monitor your pets condition.

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.

  • Chewy is good; the food I have to buy is a racket.

    By on

    This is food I have to buy for my hyperthyroid cat. Other treatment options are expensive and/ or require monitoring (more $.) I was buying this food from my vet and prices recently doubled through them. I will continue to feed my cat this gross kibble until it no longer helps her or it stops being cost effective. While I feel bitter about forking out high high prices to Colgate-Palmolive for my pet's health, using Chewy has made it possible for me to take care of my pet in a way that makes sense for my life.

  • Chewy Has a Clue-y

    By on

    A few weeks ago I purchased 2 bags of Hills Prescription Y/D Cat Food from a nationally known pet store, for our beloved Lucius, who suffers from hyperthyroidism. They were offering a sale on all types of Hills Brand Prescription Cat Food, but not in the size that was available for Y/D. (Every other type of prescription cat food had the sale size on the shelf.) When I asked a store manager why the size I needed was not available, I was told, "Because that's our policy," along with a look of total boredom. When I got home I was still steaming, so I called Chewy. My experience with Chewy was the exact opposite.

  • Thank you Hills

    By on

    Jerry is very finicky. But he pounce on it the first time I gave it to him. He hasn't gained any weigh but at least I don't have to fight with him to take his meds. Thank you, Hills prescription, for giving us a food with the meds in it.

  • Saved our cat Maddie

    By on

    Our 17 year old cat Maddie ended up loosing her hair from the tabs, and surgery just wasn't an option with her age and temperament, so this food was her last chance despite some hesitance from her vet that it would help. Fortunately, she loved the food and her thyroid levels were back to normal after a month on this. I think we changed our vets opinion on this food as well, it is definitely an option and can help with with a cats thyroid issue. BTW, it was very quick to get this from Chewy.com despite having to get the verification from our vet. Much quicker then other online sites!

  • Great website

    By on

    The ordering was great, shipping was fast, got the food very quickly. Unfortunately my cat won't eat it. She is a very picky eater. My cat had a reaction to methimazole pills for hyperthyroid and had a bad reaction so we tried the food. Now she is on a transdermal methimazole. So far so good.

    I am so very pleased with Chewy.com! I ordered my prescribed cat food easily and it came before the vets office could get some in for me. My cats (2 of them) love the food, I was even able to use it to wean them off unhealthy treats with their own new food! Love this
