Our 12 year old shorthaired domestic x28moggyx29 is a rescue cat who has landed on her paws She spent 4 years in France with us when we lived there and now travels over with us for 6 months at a time Over there back in 2011 she was diagnosed with kidney problems and put on a special diet When we came back to the UK we could not find the food she needed over here but our vet recommended this product as as good or better then the French variety We find that she loves her biscuits and her condition has continued to improve Couldnt ask for better

I loved it Debra on 2 May 2013

My cat has bad kidneys and needed to move to renal care cat food He absolutely loves this food and so does my other cat

great as long as your cat drinks well Rosie on 10 November 2011

Cats on this diet are reknown for not drinking enough and dried foods make this problem worse As my cat loves the taste of these biscuits they make a good variation in what is a very narrow diet
