What is the difference between this and the T/D version, besides that one requires a prescription?

This food is made with interlocking fiber technology which works to clean your cat’s teeth and freshen her breath. Hill's Prescription Diet t/d Dental Care Chicken Flavor Dry Cat Food is clinical nutrition especially formulated to keep your cat's teeth clean and help control the oral bacteria found in plaque.

Approximately how many cups of food are in the 7lb bag?
Answer by ChewyJul 05, 2020
There will be approximately 4 cups per pound of kibble. The 3.5 pound bag will have close to 14 cups, the 7 pound bag close to 28 cups.

Is it the size of the kibble that helps remove plaque by crunching or is there a component in the formula that helps remove the plaque? If so, please tell how it works. Thank you
Answer by ChewySep 23, 2021
The unique Oral Care kibble has an innovative texture designed to work like a toothbrush as your pet chews. Additionally, the interlocking fiber technology cleans teeth to help freshen breath with every bite.

New to this food

Our Vet recommended this food for our cats oral health. We were not sure how well they would adjust to it but was necessary not a option. We mixed half the Oral Care food with their regular food for a week; than each time we filled the bowl more of the Oral Care food was added than their regular food. They adjusted to the Oral Care food in a week, with only one stomach upset by our older and most sensitive cat, that first week. He loves this food as well as the other two.

Needs better seal on bag

I can’t speak to the effectiveness of this on my cat’s teeth yet, but I can say that the seal on the 7 lb bag is very poor. It doesn’t close properly most of the time so the food gets too hard; when I first bought it you couldn’t hear my cat eat it but now it makes a hard crunch. He likes it but I’m going to have to throw out half the bag. It’s supposed to let the tooth sink in, scraping it; not break in half with a cracking sound.

Great stuff

Much loved by my 3 guys. A replacement for Royal Canin's prescrip SO indexed dental food. I use it as a treat (ea guy gets sevl per day) to go along w/their kibble. This food has real, good ingredients, not just hydrolyzed protein. RC's non prescip dental fd was unavailable, so I tried this one from Science Dt. Very glad I did; my cats are glad, too.

Great for older cats

I started Oral Care food when my 2 cats, brother and sister, were 7 years old. The girl-cat had to have her teeth cleaned + 2 extractions, due to much tarter build-up. Her brother was OK. Now they are both a healthy 15 years old. My girl cat has had no further problems, and my boy cat is just diagnosed with some tarter build up. I was given the option of having his teeth cleaned before he gets much older. I agreed to have his teeth cleaned. I give all the credit to my cats aging healthy teeth to Oral Care. It was suggested by my vet at the time my girl cat had her teeth cleaned. My cats like it, and I also like the fact that it gives them more fiber in their diet. The kibbles are large and crunchy. I don't have to give additional dental treats to them. I have always mixed it in 50/50 with Hills prescription i/d for sensitive stomach, since my girl cat has a nervous stomach. I highly recommend Oral Care.

Great taste and works well

I have never gotten a Science Diet food and not had my three cats go crazy for it. That is especially good for this type, and it definitely improved their breath. When I ran out and didn't buy more, I noticed a big difference in my cats' breath and plaque buildup. Now I mix it in with their regular food to assure their teeth are kept in good shape.

Cat favorite

This is the only kibble I have known that NO cat will turn down! They all love it! Although it is a tad pricey I feel good that it helps with their dental care. Since the pandemic it has been in short supply locally but have been lucky to always have received it with my Chewy orders. I use this kibble a few days a week to make it more affordable while feeding Iams and purina too.

Kibble is pretty big

My cat refused to eat this food because the kibble size is so large. It is practically the size of dog food. Just something to be aware of if you have a fussy eater!

Cat Approved!

My vet said one of my kittens was getting gingivitis and recommended this food because the large pieces force him to chew. My nine month old kittens love it! Since they are still very young, I was a bit concerned of the size of the pieces, but they have no issues. I have it blended with their kitten kibble and they pick out this food and leave the Blue Buffalo.

does the job

Last year my oldest cat needed a teeth cleaning at the vet which was very expensive. Afterwords, the vet recommended I put all my cats on hills oral care of dry cat food, continue to brush their teeth every night and couple all of that with oxy French dental water additive. I did all that and when they recently had their vet check up a few weeks ago she said she saw significant improvement from last year to now. I believe they’re continuous improvement in their dental care is partly because of hills are real care in for that reason I won’t use any other cat food.

Too Large!

Cats won't eat this. Even when I pounded with a mallet to get smaller pieces they wouldn't eat it. It is very hard and they arrest attracted to the flavor.
