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.

    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

    After losing my husband a few months ago , his baby ,miss Emm came down sick . They say its her thyroid , I think it is a bit of a broken heart too. After 3 months of nothing working and watching my poor baby get thinner and sicker,I stumbled upon your website . I thought , I may as well try this ,nothing else is working . I was losing her . She has been on this for only 10 days . Already a profound difference. She is keeping her food down ,her coat actually has a shine to it . She has not gained much weight back yet ,but I am sure that will follow . Outside of removal or irradiation of her thyroid ,I feel this is the best next step . That and a whole lot of extra lovin..Thank you so much , After losing my husband a few months ago , his baby ,miss Emm came down sick .

    My cat loves this dry food! The vet recommended this for our 18 year old cat who is suffering with thyroid problems. It seems to be helping!

  • Excellant service

    By on

    Have had my cat on this food for over a year. Prescribed by vet. He has gained weight. Was able to purchase 8.5 pound bag. At the vet only had 4 pound bags. Ordered and arrived the next day. This will save me time having to go to the clinic. It arrives right at your doorstep. Can't beat that!!!

  • To soon to tell

    By on

    We are still working on stabilizing our 11 year old Siamese cat's blood levels for his thyroid. We think he has gained weight and both our cats seem to eat the food without any issues. Our next vet visit should tell us if the food is working.

  • Not Tastey

    By on

    My cat does not like this food. She just nibbles at it. I am going to have to find a way to prepare it so she will eat it. The food does work Because her T cells went down. This was a surprise to me because she ate such a small amount.

  • Very happy customer.

    By on

    I could not be more happier with the Science Diet Thyroid diet y/d and the wet can food y/d. They went to it right away, at least Allyson did, she was the one with the problem. Abby it took a little longer for her, she is on the dry and she gets a different wet food. But, I hope this will help in there recovery in the long run. I love your company, such great service ,speedy delivery. I am one happy camper. Thank you, Ms. Bonnie Sella
