Rated 4 out of 5 by from Great product for a reasonable price This is a great food for my older cat. I was having problems with him keeping down other kinds of food, but he has no trouble with this. Overall, it's a great product.

Rated 5 out of 5 by from Both mt cats and a dog prefer this over wet food. I like the convenience and love the delivery to my door. Great value. Cats love it. Easy to store. Love the rolling sealable container.

Rated 5 out of 5 by from Great Quality My Cat loves it I have been looking for a more complete senior cat food. I know Hills Science has also been highly recommended so when I came across this formula and read the reviews I went for it. My cat absolutely loves it! He begs for food each day. I will be ordering this again!

Rated 5 out of 5 by from It gives the nutrients and old cat needs and enjoys Fantastic product. Our 15 year old cat enjoys eating again and has a bounce to her steps. Thank you.

Rated 5 out of 5 by from Super Seniors need good food All my cats are over 10 years of age, with one pushing 20. I was happy to find a food that made their age and particular needs a priority. As soon as I put it out, everyone bellied up to the bar so to speak, and had a good nosh. They continue to enjoy it and it seems to be doing just as it promised. All seniors need special attention be they two or 4 legged, and I'm a happy camper this food is filling a need and fitting the bill.

Rated 5 out of 5 by from Great for older cats! My 14 year old cat wasn't interested in eating as much a he used to which is typical in older cats until I bought this cat food. Although he still doesn't make eating a priority he will spend more time eating this food and likes it better than other types I've tried. He'll race around the house now after he eats which mean he's happy with the meal!! We also tried the wet which he likes much better because of the shredded meat. Must make it easier for an old guy to eat.

Rated 5 out of 5 by from Good for gulpers Our cat has a very sensitive stomach, she throws up any food she eats. On top of that she's a gulper, so big pieces promote gagging even more, which leads to throwing up even faster. We tried every brand on the market, and nothing worked, but Science Diet small bites! She's now been on S.D. for at least 7 years, and, since she's now 14yo, we get the Senior one and she still looks and acts like a kitten, and never throws up (except for the occasional hair ball, of course)! So I would say if you have a cat with a sensitive stomach, I would definitely recommend at least trying this food!

Rated 5 out of 5 by from A great product for older cats I have just started using this age 11+ dry cat food & all three of my cats are liking it. It is a little smaller pellets than the younger age product that I was feeding them and they appear to be digesting this product without any problems.
Date published: 2016-11-22
Rated 5 out of 5 by from My cat loves it! My cat is somewhat finicky, but loved this food. It is in smaller pieces so it is easier for your older cat to eat too.
Date published: 2016-12-27
Rated 4 out of 5 by from Great if your cat prefers tiny kibble size. My cats all eat Hill's, both Science and Prescription Diets. None of them would touch this, and I believe it was because the kibble is the smallest I've ever seen. My seniors still like to crunch their food. I gave the bag to my neighbor, who has a cat with only one tooth. She said he loved it and had me order her another bag. She said it seemed to give him more energy and a shinier coat. So -- if you have cats with dental issues who need a tiny kibble, give this a try.

Rated 5 out of 5 by from Great price My cats love this food. But most of all we like the customer service and the taste. Taste for my cats and customer service and price for me.

Rated 5 out of 5 by from this product is enjoyed by my senior cats I switched my 4 cats to this food and it worked out well. They all are enjoying the food with no fuss
Date published: 2016-09-07
Rated 5 out of 5 by from The only dry food I feed my cats. I've been feeding my cats and kittens Science Diet dry food for over 30 years. Barring accidents, my cats have lived a long and healthy life that I attribute to the excellent diet provided them. I have tried other brands but usually they have been a waste of money - the cats just didn't want anything else. Additionally, when my neutered male cats suffered a bout of FUS the vet has prescribed the canned SD prescription food. I will continue to use Science Diet cat food as long as I own cats.

Rated 4 out of 5 by from They like it! When one of my cats had a severe kidney infection, I needed to switch to a more "kidney friendly" food. Since she lives with other cats, it needed to be something they could also eat and something I could afford. I did a lot of research on low phosphorus cat food and found that many of the "over 7" foods from Hill's fit the bill and I didn't have to go to the prescription foods. Since all the cats involved are over 7, this was perfect. They all seem to like the food. They've been eating this for close to a month and they are all doing well with it.

Rated 4 out of 5 by from Taste and small kibble size works. Hills Science Diet Age Defying Dry Catfood for Senior cats (11 and up)is a winner at our house. I feed it to 4 of my 5 cats and they like it. The small kibbles are easier to eat for the 2 cats that don't have many teeth.

Rated 5 out of 5 by from Cat's love it Both senior cats really liked the food. One skinny, and the other cat... not so much. It helps skinny cat keep from losing weight, and chunky cat has slimmed down a little.
Date published: 2016-02-27
Rated 2 out of 5 by from Hills A plus is that the product is for cats over 11. Unfortunately my old guy age 18 became constipated while using it. Guess he needs something with alittle oil in it which I did not see on the package ingredients.

Rated 5 out of 5 by from 2Tails Up I am cat sitting my daughter's fur babies, both 13+ years old. They seem to really like this food, which I'll keep in mind in 9 years when mine are that age. In fact, one of her cats will eat nothing else.
Date published: 2016-07-21
Rated 5 out of 5 by from Great for my picky elder cat It took some time to find a food both my cats would eat. My boy was losing weight quickly and he was skinny to begin with. This has been a life saver, literally.
Date published: 2015-12-11
Rated 5 out of 5 by from Great for Old and Young I have 6 cats. At least two of them threw up a lot. After meeting a Hill's representative at Petsmart, I bought a small bag of this food on her recommendation. The throwing up went way down, which is like an answered prayer (I mean, who wants to clean up messes several times a day?). Of the six cats eating this food, their ages are: 14, 14, 10, undetermined-but-probably-older-than-6, 5, and 1. I now have more like one or two incidents of throwing up each week. Worth the money, for sure. Oh, and I guess I should mention that the cats really like this food, too!

Rated 5 out of 5 by from Improved Fur Coats I switched my senior cats to this product about 4 months ago. I've noticed a great improvement in their skin and coats. Their fur is much softer and their skin is less flaky. Also, my long-haired cat isn't getting so many mats in his fur because it feels more moisturized.
Date published: 2016-01-14
Rated 4 out of 5 by from So far so good. We've been feeding our 14 year old cat Hill's Science Diet Senior for about a month now and she seems to like it. The kibbles are small and so it's easier for her to eat, and it's gentle on her stomach. She likes Hill's Science Diet more than she did Blue Buffalo for Sensitive Stomachs. She actually started to lose weight with Blue Buffalo and was vomiting so that's what prompted us to change. It's early days yet and that's why I haven't given 5 stars. I'll review again in a couple of months, but so far, we have a happy cat again.

Rated 5 out of 5 by from 12 year old loves it W are pleasantly shocked that our twelve year old guy likes this dry food. He's always been fuss with dry having been an indoor/outdoor farm cat his whole life. He eats this with no reservations and his black Persian-like coat has never looked better.

Rated 5 out of 5 by from Good quality food Since both of my cats are quite elderly, my vet recommended this food for them. They love it so I am happy.

Rated 5 out of 5 by from Very great and works! I have a 16 year old kitty, and lately as she aged her hair was getting dull and she was being overly tired. I am a vet tech who trained with Hills with nutrition with online courses and i learned a lot from it. As my cat is in the final stage of life, and she needs a diet to be special to that. As soon as i switched her to this in a few weeks shes shown a great improvement. She is more happy, has more energy, her long fur is silky smooth and no dander issues She is acting more happy, and keeps weight on her as this food is easy for felines with lost teeth. My other 11 year old male tabby also sneaks in her food he also acts more active.

Rated 5 out of 5 by from LOVE this food! My 15 year old cat is like a kitten on this food! We needed to decrease her protein level so I tried this food. She is running around all the time and eats this food like crazy. She has Hyperthyroidism and has been taking meds for over a year. She eats Fancy Feast canned and this food. What a change!!!! Maybe they put catnip in it-LOL

Rated 5 out of 5 by from Our "Senior" Cats Love This Cat Food Our two "Senior" Ragdoll cats made the switch to Hills Science Diet Age Defying cat food several months ago. There were no problems with the transition...they both liked the taste and the smaller kibble size is perfect for our one Ragdoll who had lost a tooth. Within a few weeks we noticed fewer digestive issues and an increased energy level. Also, it cleared up the eye discharge that one of our Ragdolls had had for many years. We are very pleased with this cat food !!!

Rated 5 out of 5 by from Helps Raise Beautiful Healthy Cats We have 3 cats which are litter mates and are 12 years old. From the day we got them at 10 weeks we have fed them only Hill's Science Diet. They've had every age specific type of food Hill's offers. They have now progressed to Hill's Age Defying. It's awesome. The small kernels are much easier for the cats to eat and easier on their old teeth. Also, Age Defying is easier on their digestive system. Our cats have always been healthy with thick, shiny coats. I wouldn't feed our cats any other brand. Have been using Hill's Science Diet around 20 years. We started with another cat we had that lived to be 18 years old.
