Great quality product and very good price

by Louisa -

Very good product, can be a bit pricey as it is a special diet food but the special offer makes it more accessible. Overall the service was impeccable, it arrived fast and in great condition. The website is easy to navigate and I found all the c/d products I require for my cat.

Great product, great value

by Neil M -

Having being recently advised from a trip to see the vet with an unhappy cat that I needed to buy a specific food that would aid in his recovery and wellbeing. I have 2 cats and figured it would be easier to feed them both the same rather than investing special bowls that work of their microchips. I bought a smaller bag of the Hill's Prescription Diet C/D Urinary Stress food initially to test and can say that both of the cats love it; hence the big bag! The one who needs it is a much happier cat these days and I would very much recommend the product.

Does what it says

by Pinkbunny -

Was recommended to my by my vet as my poor cat had a kidney stone, she now has to eat this for life as it prevents it happening again, she eats it no problem. The price at Petshop is far cheaper than through my vet and the customer service is excellent 😁
