Rated 4.7 out of 5 by 60 reviewers.
Rated 3 out of 5 by Seems to work My cat is hyperthyroid. She was on medication, but she was experiencing side effects, so the vet switched her to the y/d diet instead of the k/d diet she was on with the medication(she also has kidney disease). This has been effective so far in keeping the symptoms of hyperthyroidism down, and on the next check up I will find out if it is keeping her T4 levels low enough. I don't think it is the healthiest food for her, her coat is not as shiny as it used to be, but given very limited options for a diet, and not having enough knowledge to make a diet for her myself, I'm glad I at least have this option for her. It is very smelly and has dyed my measuring cup yellow, but Roxy eats it. May 13, 2016
Rated 4 out of 5 by Cat actually seems to like the taste! The best thing about this product is that my cat will actually eat it. Even my other cats who don't have thyroid problems want to eat it. I can't say the same for the canned food; but the kibble is a success! Now, to see if it helps his hyperthyroidism. May 19, 2016
Rated 5 out of 5 by Special Food Works great for my cat with the thyroid condition. May 9, 2016
Rated 4 out of 5 by Cheaper product than through vet Once the product was approved through the vet, product came in assigned time of 2 days. Would recommend for other people to buy from Chewy.com. April 28, 2016
Rated 4 out of 5 by High Price Cat loves it, seems to be helping. Price keeping me from giving it 5 stars. May 2, 2016
Rated 5 out of 5 by Helps a lot My cat got very thin and was vomiting a lot due to hyperthyroid and this food has helped her tremendously. April 18, 2016
Rated 5 out of 5 by cat is doing better Tried this for my 17 year old cat that had thyroid levels off the charts. This with his medicine did the trick they are now down to normal just wished there were more flavors. April 15, 2016
Rated 5 out of 5 by Great product, reasonable price Thanks to this cat food, I don't need to give my aging cat the daily pills she'd otherwise require. This is a cheaper alternative to pills, and saves my wife and I from having to struggle to get our cat to swallow them. Very grateful! April 16, 2016
