Answer by tomcatNov 04, 2022
my 25 yr old cat is the same way. i mix this with fancy feast pate but you could use a brand your cat likes too, about 60/40 mix 40% k/d food.

Cat enjoys the food

Our vet told us our cat Blossom had high kidney values so prescribed this food for her. She used to always snitch the c/d food her sister eats so she was happy that she got her own food that she likes just as well. She hasn't really been on it long enough to know if it's working but i'm glad she likes the flavor.

So much better than the chicken flavor!

My two cats devoured this, they love the ocean fish flavor. The chicken product was awful, it looked like they were trying to eat rocks as the kibble was so hard and crunchy. As a result, they ate as little as possible and were always hungry for something more. Din't have this issue with the ocean fish, they eat it eagerly.

4/4 cats disapprove

I have four cats and not one of them will even go near a bowl that has any amount of this food in it. Don't know if it has a weird odor or what, but they do not like this food or the chicken flavor version of it.

Product is great, price not so much

I was shocked to find out that the price of this has jumped up almost $10 out of no where. We are not talking over several months or years even. I literally ordered this same product about 3 weeks ago and now it's almost $10 more when it was already over $60 a bag. The wet food I purchase of the same brand has jumped up a significant amount as well. It's ridiculous to charge us this much when our pets rely on this food to be healthy. Very disappointed. I have been buying from chewy because it was more affordable and more reliable than purchasing from my vet. Now I am considering finding somewhere else to shop.

KD - excellent

My cat was diagnosed with KD when I rescued him five years ago. All I can say is that his numbers have not worsened, so both the dry and wet KD food seem to be keeping him healthy!

Cat loves it

Our cat needed k/d for both her kidney and urinary tract issues. She refused to eat the chicken so we were concerned what to do. The vet suggested the Ocean flavor and she loves it. Just very expensive.

All the cats eat it.

All of my cats eat it, so 4 stars for that reason! It's not my cats' favorite food, but they eat it regardless and seem satisfied with it.

My cat loves it

Luckily my cat isn’t picky about her food because she has no problem eating her KD food. She scarfs it down.

A favorite for my feline!

I know this product can only help my cat if she eats it. Thankfully, she loves it!
