Blue Buffalo Natural Veterinary Diet K+M Kidney + Mobility Support Grain-Free Dry Cat Food, 7-lb bag

I like that the product is grain free. My cats do very well with Blue Buffalo grain free products. I don't know much about the Kidney and the mobility food because my cats haven't been on it for very long. So far there has been no problems.

My boys don't usually like Blue Buffalo products, but after trying the kidney support, they did eat it at first, probably because it was something "new". So the first few days I could see they were eating it, but less and less the following days. I am continuing to feed it to them, hoping they will find a renewed fondness for it.

I have 2 elderly cats with kidney disease and I was having a really hard time treating it until I found this because one of the cats can't eat corn and it's in all of the other kidney diet foods that I found. Both cats seem to tolerate this well. I is extremely annoying though that it's a tiny 7 lb bag. I feel like I'm constantly having to have more shipped. They need to offer a larger bag.

My cat won’t eat any of the prescription foods! This includes other renal food we purchased! Don’t know why. Maybe too finicky. Chewy is a fabulous on line store and very helpful!

So I was able to basically cold-turkey these cats on to this food. I know that’s not typically recommended, but I tried mixing and they were just pick out the old food. I tried the other formulas from other brands, no luck at all. Everyone did great on Blue Buffalo, absolutely no gastro troubles and everybody loves the food. I have 3 x 12-year-olds, one with more severe kidney issues, the other two, well, they are 12. All siblings. HOWEVER what’s up with these frankenberries mixed in? These little dark kibbles, all the cats reject them. If they are supposed to hold important nutrients, no luck here. I clean up a little pile of them every day outside of the bowl, see photo.

I have hopped from one other dry kibble grain-free brand to BB with these cats their whole lives, and they have always loved BB, but they have never liked the “LifeSource Bits.” Seems more like a marketing ploy to make the food look interesting to the humans! I wish BB would go ahead and mix these nutrients into the actual kibble. … more

My precious Odie diagnosed with kidney failure - refused to eat anything. My Milo who tests very healthy, also refused to eat anything when Odie became ill. But Milo did eat a little of Blue Buffalo K+M dry - while turning his nose up the food he loved before. I fed Odie another RX can food and he began nibbling the RX dry also. Both are eating it now. Still feeding Odie the can and he is perky and wanting to play again.

My cat's vet recommended he begin a kidney support diet. We tried Hills and it was no-go. He wouldn't touch the dry and ate the wet reluctantly (previously I fed him Blue Basics dry and assortment of good quality wet food). He then began throwing up the wet. He likes this dry food very much! Thank goodness!!

Our 13 year old was diagnosed at the very upper limits of functional kidney values a few months ago. Our vet recommended putting him on one or both of the two main prescription diets for pets. After seeing the ingredients (basically pork digest and saw dust), I did my own research. I found this food, requested the rx, and our cat loves it. Even his little sister goes after this food when she is done with hers! I love that this diet includes joint support and I think more diets should include it. Probably they want to make money selling additional supplements that cats don’t like. Wish I had found this food sooner- the ingredients are fantastic for a lower protein diet.

My cat Shadow, a 14 year old rescue was adopted by me two months ago. The first thing I did was take her to my vets to get a physical. It was discovered that she was in the very early stages of kidney failure. Vet gave me several samples of wet and dry foods to try for her condition. Blue K+M was the only one who's ingredients were acceptable to me. There are no by-product meals, corn, wheat or soy in this food. All the other samples were mostly just that kind of ingredient. One sample didn't even list a meat source. Cats don't digest plant protein efficiently. Even though she's in early kidney failure, I feel she needs real meat. She has transitioned to this diet and likes it. With My cat Shadow, a 14 year old rescue was adopted by me two months ago. The first thing I did was take her to my vets to get a physical.

My first rescue passed two years ago, but I used Chewy for her needs too. Chewy is a great company to do business with because if something is wrong, they will make it Right! … more

Recommended by my cat's vet. My cat is in stage 3 kidney failure. He loves this food and his coat is nice and shiny. Also vomits much less now.
