I have a 17yr old cat with several health concerns including sensitive stomach. Like most cats he’s a picky eater but loves this dry food and it doesn’t upset his stomach. The kibble size is small enough that he’s able to eat it even with some teeth issues. I had him on the Adult formula from this brand but the kibble size was a little larger and he had some difficulty eating it at times. I slowly transitioned him to this kibble over the course of 3 weeks or so with no issues. Our vet recommended the Senior formula and so far (on our second bag) he’s doing great.

The cats love it. I also purchased the ROYAL CANIN FELINE HEALTH NUTRITION AGING 12+ Loaf in Sauce to fortify their diet after doing some research. Although it's still to early to determine if it is helping with age related issues (a little arthritis & unhealthy coat), they love both products. I'm hoping this does the trick.

I have been buying this food for about 6 months for my 17 and 11 year old cat. The 17 year old has ckd. Neither cat will touch it now. I opened two fresh bags and they both smell very different than before. Our 17yr old cat started getting sick because he wasn’t eating. I will be asking for a refund!

I started using this food for my then 12 year old cat, many years ago. She is now almost 19, and doing so well. This and some soft food do wonders for her. If you have an older cat and or one that may have issues with their urinary or kidneys. I recommend this food.

I'm truly disappointed with Hill's products. My cats have slowly rejected all of their food products. I would test out any Hill's products before buying in bulk

Hard to find things a cat 18+ can eat. Wish the kibble was a little bit smaller, but I haven’t found many. She gets wet food, but it’s nice to have to have some
