Well, Adelaide can be a fussy eater but she will eat the regular KD dry food if her non-prescription food bowl is empty (which I let happen overnight to encourage her to eat the prescription stuff), but she absolutely will not eat the KD with Mobility Care added ingredients. I don’t know what the difference is other than the addition of some glucosamine and condroitin, but when she smells the kibble bits she turns her head away in disgust and will not touch it. Interestingly enough we also tried Cosequin for her arthritis for several months and she had bad poop issues as a result, so I stopped that and she now gets monthly shots for arthritis pain from the vet. Maybe she has an allergy to Cosequin or Glucosamine or something like that and reacts to the odor in this kibble because of that?? Anyway, I think I will donate the rest of the opened bag to my vet’s office. Purrhaps one of their clients can use it for their less discriminating kitty. This was a bust for us.

This food has made an obvious difference in Tiger’s mobility. I took her off the food for a month thinking it hadn’t made a difference. I put her back on it and within a week I saw a huge difference. Her limp is noticeably less. I highly recommend this food.

K/D he will eat.

My cat has kidney disease and doesn’t like the food!!! Until I found Hill’s KD/JD. He likes the wet food & the dry food plus beside the kidney support he gets joint

My cat has kidney disease and doesn’t like the food!!! Until I found Hill’s KD/JD. He likes the wet food & the dry food plus beside the kidney support he gets joint support as well. My cat is running, jumping & acting like a young cat at 17 1/2 years old. We still provide him with fluids, but the food has made an enormous difference.
