Hill's Prescription Diet Y/D Feline

Prescription Diet Y/D is the safe effective and easy way to restore thyroid health in 3 weeks. Hill's Prescription Diet Y/D Feline is a scientific breakthrough - the first and only clinically proven pet food to help support your cat's thyroid health.

The thyroid gland produces hormones that have an impact on a variety of metabolic functions from appetite regulation to heart rate, gut function to behavioural characteristics. A cat with a healthy thyroid has a body that's kept in balance, with the end result that your cat feels great.

It is available in 2 x 1.5kg and 5kg bags.

Key benefits of Hill's Prescription Diet Y/D:
- Great taste your cat will love
- Supports kidney health with controlled phosphorus and low sodium
- Visible improvement in skin and hair coat

Ingredients: Liver, pork, chicken, maize, rice, animal fat, vitamins, digest, cellulose, minerals, trace-elements, fish oil, L-carnitine.

Important: Iodine from other pet food sources compromises the effectiveness of low-iodine nutrition, so it's critical that you follow your vet's feeding instructions carefully and feed only Y/D.

For orders over £29 postage is free. For orders under £29 we charge £2.99 for postage

Once again excellent service starting with easy access on your site to delivery of goods and my cat loves it


I gave this to my cat to begin with even though she was hungry she wasn't too keen on it. To begin with I put a few drops of her usual food to get her used to it. I now mix it with a little of the we y/d canned food. She will now eat it on its own as well.


Macy's fur is a lot better and her tachycardia is at a better level. This food was recommended by the vet. She enjoys it too.




Cat enjoyed dried food and I will try canned food later


Just as you expect from hills 👍




Blended with cats usual food for a week and now in it exclusively, no problems at all


Suits my catvwho has a thyroid condition.
