Feeding Instructions

Because iodine intake from other food sources -- treats, another cats food, etc. -- can compromise the effectiveness of low-iodine nutrition, its critical that you follow your veterinarians feeding instructions carefully and feed only y/d.Adjust feeding amounts as necessary to maintain optimal weight. If you are unsure, ask your veterinarian. For best results & safety practices: Cover and refrigerate unused portion. Gradually transition to your pets new food over a 7 day period. Exclusively feed the recommended Prescription Diet dry food & canned food. Keep fresh water available at all times. Have your veterinarian monitor your pets condition.

Transition Instructions

A gradual transition to a new pet food is important to avoid digestive upset. To transition, mix your pet’s current food with the new food. Over 7 days, gradually decrease the amount of the current pet food while increasing the amount of new pet food. In some cases, your veterinarian may recommend no transition or a shorter transition time.

Rated 5 out of 5 by Great way to shop! I need prescription food my elderly cat. Chewy was the way to go: * lower price than the vet * delivered to my house, free shipping, no need to call vet ahead of time and make a trip to get the food * easy ordering--I supplied the vet's name and phone number and Chewy took care of the rest * fast delivery--roughly 36 hours from placing order to receiving it Thanks, Chewy! I recommend you highly! January 21, 2017
Rated 4 out of 5 by Good product My pet has been on since 2015. She has gotten used to not having anything other then this product in can and dry food. I'm satisfied with it January 9, 2017
Rated 4 out of 5 by Speedy delivery! My cats prefer the y/d dry over the wet. That's opposite to what it was with Friskies. Just wish it came in a fish flavor or one they find more appealing. My 17 year old cat is losing a bit of weight, unfortunately, because she just isn't eating this wet food like she needs to. January 2, 2017
Rated 5 out of 5 by The product is good The product is a little dry but you have to microwave it a little and add a little water. My cat eats it just fine. January 5, 2017
Rated 4 out of 5 by Minnie liked it! My cat was very picky but she immediately went for this food. She wolfed it down. However she was pretty sick so it might have been too late to help and she passed soon after I started feeding it to her. I don't think it had anything to do with the food and I would recommend trying it if your cat has thyroid issues December 26, 2016
Rated 4 out of 5 by Cat eats it We have a finicky cat. Start the product by mixing with your cat's regular food and a little hot water to make a broth. Our cat transitioned very easily. December 13, 2016
Rated 4 out of 5 by Cat eats after mixing with water At first, the cat would not eat this food. It is extremely dense and dry. It's almost like peanut butter consistency to the cat. The cat was used to the grilled cat food with the 'sauce' and the sauce is key. I divide the can in to four portions and give 1/4 of can per day. I chop up the food so it's in small pieces and add water/stir to make it soupy. The cat drinks the sauce at a minimum and sometimes eats the food. This keeps the hyperthyroid issue under control and is better than applying expensive meds. She also has the dry food available at all times. November 10, 2016
Rated 2 out of 5 by Jury is out.... My kitty desperately needs to like this food and he ate it up the first 6 days or so.... now won't touch it. I cannot get him to eat in any manner. I'm fast running out of options to keep food in him. I SO wish this came in other flavors to keep him interested. It is too costly to have ordered so much more and now he won't eat at all. :( November 16, 2016
