Re-checks are at the discretion of your recommending vet; it is recommended that cats with compromised kidney function should be seen more frequently.

Brilliant for my 17 year old cat who had a thyroid condition. He loves this food. Victoria Rataj-Worsnop on 20 September 2021
Good Value MU on 14 December 2018

Having a cat that has a under active thyroid, it is a mission to get food that isn't too expensive, whilst still maintaining your cats health. Pet Planets y/d food is about 50% less than what you would get in a vet's I would recommend this product, it does have a bit of a smell, but you get used to it and I would suggest keeping it in an air tight container as once you open the bag it never quite seals correctly again.

Excellant Sadams on 20 October 2016

After my cat was diagnosed with Thyroid problems I was pleased that I was able to use this product and avoid having to give my cat dreaded tablets to control her condition Most pet owners know how difficult it is to make a pet take tablets so using this food is so much easier and she loves it

She like them! pkmshaw on 29 August 2021

Our cat is very happy to eat these which is just as well as she can only eat a special diet for hyperthyroid cats. She also eats the tinned equivalent but this is her favourite.
