    Rated 5 out of 5 by from I'm a believer My 16 year old Molly showed slightly abnormal thyroid and kidney functions on a recent blood test. The vet suggested y/d. He told me this food would be good for both conditions. I was a little skeptical- my cat would only eat one kind of dry cat food previous to this. I started mixing in a little of the dry y/d with her regular food. After a couple of weeks she was eating the y/d without her old food mixed in! An unexpected benefit of the diet change- Molly had been throwing up fairly often- I thought she was trying to pass a hair ball, except there was rarely any hair. After switching to the y/d, she stopped thowing up! Whether that was due to an improvement in her thyroid/ liver function with the new food or just the quality of the new food I can't be sure, but it works!! I'm a believer!!!

    Rated 5 out of 5 by from Expensive but worth it My neighbors domesticated a feral cat and then moved away. The cat kept returning to the neighborhood from about 15 miles away (4 times) so I adopted him or maybe the reverse. Amazing solid black cat, Rex -- not sure of his age but he's no spring kitten. Took him to the vet for a checkup and discovered hyperthyroidism. Didn't like the 3 options the vet gave me for managing the malady so with google's help I discovered Hill's Y/D. I asked the vet why he didn't suggest it and he said cats won't eat the stuff but if I wanted to try it he would give me a free sample. P.S. My cat loved it right from the get go, has been on it for a year and a half and has maintained his weight, shiny coat and high normal thyroid readings. The vet is amazed and cites my cat as his first success story with Y/D.

    Rated 5 out of 5 by from easy transfer from old food. Thrived well on y/d. Ate y/d as his meal and also used it as his treat, since he could not have any other food. no more pills to buy or forgetting to give them twice a day.

    Rated 4 out of 5 by from My sweet 16 yr old Maine Coon has become Hyperthyroid After Willie Woo's bloodwork, the vet said lets try this food first to see if we can avoid pills everyday. ( I'm sure you know how hard it is to give a cat a pill) He was starving all the time, crying and wondering all around the house like he was lost or in pain but after one day on this food, he has settled down and now about a month later, much better. I am waiting for him to gain back some weight and he should be good to go. He also eats some of the canned y/d too. The y/d dry food is so expensive though and on a fixed income, its a real concern. Especially because I have a dog on meds with a heart condition and 2 other aging cats. I am still glad to see my big boy feeling better.

    Rated 5 out of 5 by from This product works Our vet recommended this product as an alternative for Hyper Thyroid for our cat and it seems to be working. The medicine she was taking caused her to much stress so we were relieved when she took to the dry food. She is doing great after her first bag.

    Rated 5 out of 5 by from Smaller cans? My 13 year old cat has been on Y/D food for a couple of years, and has now lost interest in the wet food except when I first open the can. I notice someone else has that same problem. A newly opened can interests her greatly and she will eat 2-3 tablespoonfuls, but after a can (well sealed) has been in the refrigerator for a day or two she loses interest. I would be interested in smaller cans if they were available.

    Rated 5 out of 5 by from Bill is alive and well after 4 years ! When I took Bill into the vets, I was thinking he was near death. He had always maintained a weight of 15 pounds, and was now down to 7. After putting him on YD , 6 weeks later he was 12 pounds, and he has maintained for almost 5 years. His tumor shrunk. Now I am seeing a growth in it again, and will take him in for a visit to doc Colleen, but I tell you, the Y/D has worked great for our boy ! We are on a fixed income and the coupons when we can get them really help, but if I have to go with out steak, I sure will to keep my boy Bill alive and well !

    Rated 4 out of 5 by from Kept my cats thyroid in check If this food is fed exclusively it does a great job of keeping the thyroid levels in the normal range. The flavor seemed to be iffy for my cat. She ate it, but didn't really seem to like it. This would be absolutely perfect if they can find a way to make the flavor better. My other cats didn't want it either. BUT it does keep her thyroid levels normal and I don't have to give her any medications. That is a BIG plus. The cost of the food ends up being cheaper than the medication was. I recommend using this.
