  • Fabulous Food That Promotes Oral Health For My Feline!

    By on

    My cat is loving this food and I am so glad to have finally found a food that he likes. I cannot or have not changed his food before because he just does not like change... but he loves this and I am running with it. I love that this is going to be a great addition to ensuring that Shadow has healthy teeth and gums all while actually liking the food itself! He is even asking for food a lot less than before because he is satisfied! And I know he needs to lose a few pounds... what a great product! Thank you Hill's Science Diet!

  • HILL'S Oral Care

    By on

    I agree with many other reviewers. My Cats like this food; however the pieces are to large for the average Cat to chew. I have a manual chopper and very carefully I cut the pieces in half. The chopping causes some of the pieces to turn into dust; these I just throw out to the wild animals. I ask that Chewy.com contact Hill's Science Diet and tell them about this problem. I cannot recommend this product at this time.

  • My cats go crazy for this

    By on

    The pieces are really large, so my cats are forced to crunch, which I love. My elderly cat who had lost his appetite in recent years actually goes to eat more often since I added this to their dry food mix, and my younger ones pick this out of their bowls.

  • Great service!

    By on

    I used Chewy for the first time for prescription food for my cat ordered by my vet. He would not eat the food much and developed terrible diarrhea so I thought I was out the money. Chewy forgave the bill and sent us food he would eat which amazed me. I am a devoted customer now! They told me to donate the food which I thought was so nice.

  • My kitty has kidney issues

    By on

    This food in fish flavor is only 1 she will eat. It cleared up the crystals . She would have died a painful death wit out it. You cannot wait a single minute if your cat stops urinating or if urine slows way down, get to vet limmediately.

  • Good for teeth?

    By on

    I can't brush my rescue cat's teeth (she barely tolerates the comb), and I don't feed her dry food. But my vet suggested this will help even if I feed it as a 'treat.' That's what I've been doing, and she loves this.

  • Good substitute for TD

    By on

    I can no longer afford TD, so I went looking for an alternative. I found Hills Science Diet Oral Care. It looks a lot like TD. But it's much less messy. My cat's fur is shiny.

  • Great kibble to keep teeth clean, works as treats as well

    By on

    Fussy eating cat owner here. This is the only other kibble he gobbles after he is done with Royal canin savory dry food. The vet recommended this and it does seem to keep his teeth clean.

  • Service FAST

    By on

    I have gotten Oral Care food for my cats ever since one had to have an abscessed tooth pulled. The bigger size makes them chew more, which in turn helps with their dental health. I have used a service for shipping to my home for the past 7 years and have loved it. Recently, when I checked prices, Chewy beat the competitor for the same service by a substantial amount so I switched. Not only was the service great, easy to place the order etc., the food literally landed on my doorstep the very next day. Now that's fast! I look forward to our future of feeding my fur babies through their home delivery service.
