Rated 4.8 out of 5 by 54 reviewers.
Rated 5 out of 5 by Wonderful product We rescued a stay cat who turned out to be a dwarf. He was 3 months old and only weighed half a pound. He is now 5 months old and has gained a pound on this food. The vet recommended it because it is high calorie and he loves the taste. We will continue to feed this while he is growing. Before feeding this food he has a low blood sugar problem so he may not be absorbing all his food. In that case we may have to supplement with this for life. Any way to get a discount? :) December 29, 2013
Rated 5 out of 5 by did it's job my 16yr old toy poodle needed to get back to normal and gain some weight-he's an extremely fussy eater but ate this and it put weight back on him and got him stronger---I hope you'll never have to use this but it's good ( a relief) to know it's there-- October 19, 2013
Rated 5 out of 5 by Excellent I'm sold on Science Diet & if needed, prescription diet. However, if I didn't work at a place to get it less expensive, I don't know that I wouldn't switch. Yes, I do know what I'm paying for but that doesn't make money appear. Also, I thought we were supposed to get coupons in the mail by going through a vet clinic. Did I misunderstand? Thanks for asking. September 17, 2015
Rated 5 out of 5 by Saved Hendrix's life!!!!!! Two of our border collie pups out of our current litter came down with coccidia. After taking Hendrix to the vet for a two day stay we found out he was blind. We got him home again only to shortly lose another pup from the same thing. (In the car on the way to emergency sadly enough) Hendrix was doing well for 4 days until he was becoming increasingly more lazy and dehydrated. He went off his food and water and after another trip to the vet they gave us 3 tins of a/d to feed him with the syringe every 2 hours as he was becoming severely underweight. He isn't too much of a fan of the taste but that is possibly due to the syringe. In the last 3 days we have noticed that he has started eating on his own again when we offer him mince, he is taking water better now and is becoming more and more lively. We even got little tail wags tonight and he rolled over for a belly rub. He is now 7 weeks old and if it wasn't for Hills science diet a/d I don't think he would be with us today. Thank you for saving our pups life!!!!! February 13, 2014
Rated 5 out of 5 by Helped save his life 4 week old kitten squashed by the garage door. Took him to the vet, who wasn't sure if the little guy would make it. Survived the night, and was sent home with a/d to eat every 4 hours. Went from needing his head supported, to quickly bouncing back. Returned to vet 2 days later, and they couldn't believe it was the same kitten. Within 5 days eating a/d, the little guy is climbing out of the tub he was contained in (18 in. tall), and literally bouncing all over. Unfortunately, the kitten has no interest in nursing, just playing with it's mothers' tail, and siblings. What a fast turn around! June 5, 2015
Rated 5 out of 5 by Essential Nutrition in a can !!! My 13 year old Siamese was diagnosed with a severe illness and was not eating. A/D critical care has the consistency of baby food with absolutely no "chunks" of any sort that most other canned food has. This food gave her the nutrition she needed during that last critical month of her life after being diagnosed. My other Siamese, now 15 had acquired a taste for the A/D food as a "treat" when her mother was ill. She is healthy, but has a sensitive stomach, and will throw up other foods, so this is still her twice a day treat along with Age Defying senior 11+ dry food. Cats normally do not drink a lot of water, so my other 2 cats (1 1/2yr old girl and 5 months old boy) also get this as a twice a day treat because of the moisture content. Cats (like people) need proper nutrition to help prevent disease and illness. Thank you Science Diet/Prescription Diet for this amazing food. My kids (cats) thank you, also. January 23, 2014
Rated 2 out of 5 by pricey for something my cat doesn't really care for My cat will eat it only when he gets really hungry enough... as in -if he's not eaten any other meal for several meals. He doesn't really care for it. He sniffs it and walks away like he'd rather go hungry most times. I feel like for the price we paid he SHOULD like to eat it. May 28, 2015
Rated 5 out of 5 by A/D canned food is awesome! We love using a/d canned food on our cancer patients. Especially the ones that have had radiation therapy in their mouth or throat. Being able to use it in a syringe works great! May 19, 2015
