Try this, I am so glad I did.
My 18 year old tabby started with renal problems and uraemia. She has always been a faddy eater after an awful start in life, I hand reared her and 7 siblings from a few hours old after some creep dumped them in a verge. Turns her nose up at anything but chicken and small amounts of Gourmet gold. She got to the point of only eating a couple of mouthfuls before walking away, weighed nothing wondered around yowling whilst looking for some inappropriate place to pee. Any prescription low protein food was a no no. But...guess what? Hurrah! She eats two tins of this a day,along with some chicken and has steadily put on more than a kilo in 8 weeks, no more yowling, is calmer, happier and stopped being a miserable witch with the other cats.
I am thrilled, especially as I am not a fan of commercial pet food. She likes both flavours, the fishy one is not too fishy, she never liked fish but eats this as well as the chicken. Try it, as a hater of mass produced pet food I'm having to eat my words on this particular product. She will be having more blood tests next month to see how much her blood work has improved. It is such a relief to see her so happy with herself and looking so well.
