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: Cover and refrigerate unused portion. Gradually transition to your pets new food over a 7 day period. Exclusively feed the recommended Prescription Diet dry food & 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.

  • Great if water is added

    By on

    I bought this food after trying to give my 13 year old cat meds for her thyroid. She ate her regular food with meds in it for 3 days then she quit eating her food all together. Reading online the side effects for that med was loss of appetite. So this was the second thing to try. I couldn't believe how dry this food is. You have to add some water to it. When I gave the food to my cat I couldn't believe she ate it like she was starving. My cat has been eating this for a week now. My cat gained her weight back and is looking better than ever. I wish there was more variety of y/d food instead of just pate. The only reason I gave this 3 stars.

  • My boys love it!

    By on

    My boys absolutely love this food. They had no issues transitioning, and seem to barf less than before. My cat with the thyroid issues had already put on a couple of ounces!!! My only complaint is that they love it so much, they always want more and being so expensive, I cringe at their enthusiasm.

  • Kitty Thyroid care

    Happy to say that my cat likes it and eats it all every day. I give her 1/4 of a can each day besides the dry Thyroid Care food. She also likes that and already is gaining some weight back.

  • Diet change rewuired

    By on

    My 14 yo cat had been a on Hills j/d for several years because of joint issues. The vet recommended the move to y/d when George developed thyroid problems. The food is thicker, pastier, not a loose grind. I add filtered water so it isn't so sticky. After several weeks on this diet, he seems to have adjusted well.

  • Yummy, please serve me more of that tasty cat food!

    By on

    Sammie has hyperthyroidism and for the last 10 months I served him the YD dry cat food. I would let it on the floor for him to eat as he pleases. I figured that, by now, he might be bored only eating the YD dry cat food, so I decided to try the wet canned US cat food. Like the dry meal, he just loved the wet canned cat food. He would polish up the bowl. Being very frugal, I divide the can into 3 parts and add some warm water (it is sort of dry) and he lives it! I serve it once a day at supper. Diane Roach

  • Great product

    By on

    Having to put my cat on a prescription food was my one of the choices my vet gave me for my cat's hyperthyroidism. My cat loved it from the get go and has gained 3 oz. in little over a week. She loves the food and eats more of it then the old food. Am very delighted with the results

  • hyperthyroid

    By on

    I took my very large 14 year old cat to the vet for a check-up. He had lost 6 pounds! After blood work, my vet determined he had hyperthroidism, normal level is 1-4, his was 7.1. I started him on the yd diet, both canned and dry. He loves the food and a month later his level is 2.3! The canned food is very dense, so much so, that after adding a little water, I am able to get 6 feedings per can. It's expensive and has the worst ingredients, but it works. Unfortunately, the vet said he would probably gain the 6 pounds back.

  • Expensive way to find out....

    By on

    Since there are no trial sizes offered , I am pretty bummed that I spent so much money on a product of my cat will not try. I am sure the product is excellent, but my cat will not come near it. Have tried numerous ways of introducing it to his diet, but he will not eat it!

  • They love it!

    By on

    My senior hyperthyroid cat (and his healthy brother) started y/d dry recently. They seemed to love it and adjusted very quickly, but also missed their canned food. I hesitated to try y/d canned after reading reviews that cats didn't like the consistency and wouldn't eat it. Fortunately, I followed the advice of a few reviewers to add a bit of warm water to soften this food. They love it! After about 3 weeks on dry (and about 2 weeks on canned), my boy is starting to gain weight.

  • Food helped my cat regain her normal weight

    By on

    This product has really helped my 10 year old cat with thyroid troubles. She has regained her normal weight. She doesn't eat a lot of the wet food but gets great nutrition from her portion. She also loves the dry food version.
