Hill's y/d is the first and only clinically proven nutrition that is specially formulated to help support your cat's thyroid health. The y/d diet carefully restricts the levels of iodine to help support thyroid function, particularly in cats with hyperthyroidism, whilst providing a complete daily nutrition with a taste your cat will love.
Hills y/d diet also provides extra benefits in addition thyroid health, including:
-Supports kidney health with controlled phosphorus and low sodium
-Helps maintain bladder health with controlled mineral levels
-Promotes heart health with essential nutrients like taurine and carnitine
-Promotes healthy skin and a luxurious hair coat with high levels of omega-3 and -6 fatty acids.
IMPORTANT
Because iodine intake from other food sources -- treats, another pet's food, etc. -- can compromise the effectiveness of low-iodine nutrition, it's critical that you follow your veterinarian's feeding instructions carefully and feed only Hills Y/D.

Excellent product, my Cat really likes it.
Customer recommends this product
My Cat needs this food, because of a thyroid problem. She has put on weight, and seems to like it. As she is 14 years old, don’t want her to undergo surgery.
Customer recommends this product
My cat loves the dry food (Not the wet) and he's much happier and has even put weight on. This stuff is great. He still gets a little iodine.
Customer recommends this product
My cat is on an iodine-free diet to control a thyroid tumour. y/d products have kept her condition under control for 4 years. The wet food gives her a nice change from the dry food, and she really likes it.

Below are some recent questions we've received regarding Hill's Prescription Diet y/d Thyroid Care with Cat Food, including answers from our team.
Cindy
My cat normally eats dry food and has been recommended the y/d diet by our vet. Can she continue just eating the dry food or does it have to be mixed with the wet food?
You can choose wet or dry, or a combination of the two, it will be fine as far as her hyperthyroid treatment is concerned. The main issue with this diet is that it tastaes a bit boring to cats, so they tend to go off it after a while. Using both wet and dry can help to provide interest, so I would recommend that is what you do. It is important that she does not eat any other type of food at all.
Bailey
My cat has a thoroid problem & won't rejects Felimazole tablets in any form.
Q1. Does the y/d only come in one variety (which my cat doesn't like) - are there any other varieties.
Q2. Is there any way of making it taste like Chicken or Beef?
Thanks
There is only one form of y/d diet and it is true that lots of cats do not enjoy it. Adding anything significant to it to improve the flavour will probably prevent it from being fully effective, so I would not recommend that. If hunger will encourage your cat to eat it then you will have to work on that, but this is a problem for many cat owners.
kay barnett
i can't find anywhere, whether it is OK for prescription y/d to be fed to other healthy cats within the household, or must it ONLY be fed to the cat diagnosed with hyperthyroidism?
This diet is safe for other cats to eat, but ideally they should get some other foods as well. A hyperthyroid cat should not be allowed to eat anything else at all. The y/d diet is not especially tasty, so your other cats would probably prefer other food anyway. You have to make sure you do not offer any other foods when the hyperthyroid cat is present, or that one will not want to eat the prescription food either. If you can cope with the hassle of organising the feeding, the y/d dose seem to be very effective.
