Hills 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!

Dry food available in 1.5kg and 5kg bags.

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.

Key benefits of Hills 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.

Hills Prescription Diet Y/D 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.

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.
