Rated 4.6 out of 5 by 186 reviewers.
Rated 5 out of 5 by Awesome Service This product is vital to the well being of my 15 year old kitty, Chuckie, who has gone from 21 lbs. 16lbs. in less than a year. High thyroid, I find, is common in elder cats. I'm 72 yo, and Chuckie is my "baby boy". I bought my first bag at one of the 2 prominent pet stores known nationally and paid $64 incl. tax. Being an avid Googler, I came upon Chewy. I like the design and quickness of the page, and the retail is $10 less, in addition saved another $10 for auto re-order! Here is the kicker... I received this product well packed in an oversized box, LESS than 48 hours after I ordered, and NO handling fee or tax! Highly recommend all you pets that have owners! Plus, their online chat is knowledgeable August 16, 2016
Rated 5 out of 5 by My cats love it. My cats cannot get enough of this food. They love it! August 21, 2016
Rated 5 out of 5 by Gets the job done! I recently adopted a cat from a shelter and told she was in perfect health. A week later, there was blood on her urine. I took her to the vet immediately. The doctor drew a blood sample and shocked me the next day with the results. My cat had an Overactive Thyroid which can cause heart and kidney problems and, could be fatal if not properly handled. Hill's Prescription Diet y/d Thyroid Care Original Dry Cat Food did the job. She is now a healthy, happy cat and there is no way I could be more pleased. And thanks to Chewy, I got my first autoship order at a 20% discounted rate AND used a coupon. My heart is again full of joy because of this prescribed diet and the kindness in which the Chewy employees showed me as I was in tears on the phone with them at the time. July 8, 2016
Rated 4 out of 5 by Good service Good service and help with getting in contact with the vet for perscription for special diet food. July 14, 2016
Rated 5 out of 5 by Great I have been feeding my cat who has hyperthyroidism the wet food but had to go out of town so i bought a bag of the y/d thyroid care dry food for his self feeder. Without gradually switching foods he immediately ate dry food and loved it. It's very moist which he loved but just make sure you reseal well. I will be keeping this on hand for when I have to put out his self feeder. July 19, 2016
Rated 5 out of 5 by Controlling thyroid The diet is working perfectly at controlling my cats thyroid. He loves the food. July 9, 2016
Rated 4 out of 5 by Hoping for great results My almost senior cat was diagnosed with hyperthyroid. After medicating our last cat with methimazole, both pill and gel form, we strongly wanted to try something different. Our vet recommended trying Y/D, and so far, I'm seeing some improvement, especially in weight gain and shinier coat, but also in seeming a little calmer. The real test will be in a couple of weeks when his thyroid hormones are rechecked. Our cat likes and eats the dry food quite well so far. June 9, 2016
Rated 5 out of 5 by Great service and delivery The product we ordered arrived promptly and in good condition. June 21, 2016
