Feeding Guide

Daily Feeding Guide:

Important Feeding Information

  • These amounts are a starting point only. Your cat may need less or more food to maintain proper weight. Adjust as needed. If you are unsure, ask your veterinarian.
  • With your veterinarian's approval, mix increasing amounts of your cat's new food with decreasing amounts of the old food over a 7-day period.
  • Prescription Diet formulas are available in a wide variety of dry foods and treats for your cat's unique needs, and canned foods with delicious flavors your cat will love. Supplementation with other foods or treats is unnecessary and may decrease the effectiveness of the food. When using with canned food, decrease the amount of dry food to avoid overfeeding.
  • Keep fresh water available at all times!
  • For best results, have your veterinarian monitor your cat's condition.
  • To prevent suffocation, keep this plastic bag out of the reach of pets and children.

Controls her hyperthyroidism without any medication. Excellent product. My cat was quite aggressive growling at night and drinking a great deal of water. The Vet was talking radiation and then I learned of YD formula. After a couple months on this food her thyroid labs returned to normal. I highly recommend and avoided having to administer pills which would have been a mutual nightmare. November 22, 2013
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. October 1, 2013
Bean's thyroid has returned to a normal range with the y/d diet This product is wonderful. My 17 year old cat was too old and sick for any other thyroid treatments. Oral medication did not work and had to be stopped - it caused intense itching above the eyes that resulted in sore areas. Bean was quickly running out of options. Since Bean has been on the diet (wet and dry food), it is obvious he feels much much better - his coat is shiny again, he has started to play again, and he looks better than most cats his age (per the vet tech at my vet's office). Bean has gained about 6 ounces since the diet. I feed Bean the wet y/d in small portions every 3/4 hours and always keep the dry food out for him. I have my best buddy back again and I am grateful!

No more weight loss! Our 14 year old loves this product and she has stopped losing weight. She still has plenty of energy but she's not zipping around the house like a Tasmanian devil and doesn't live at the water bowl. Thank you! July 27, 2014
Helps my cat My cat is doing much better since being on this cat food. I can definitely tell a difference from now and when he was eating whatever he wanted to eat. His overall health is so much better. I just would not have realized how it would help him. thanks so much July 26, 2014
Great option for thyroid control After the thyroid medication caused liver issues with my senior cat, we switched to the y/d food to control his hyperthyroidism. Within a month, his thyroid was back to normal levels. His eyes are clearer, his coat softer, fuller, and shinier. He has a lot more energy, and his attitude has improved. After 2 months, his weight has maintained, and hopefully he can start bulking up. He enjoys the food, but does seem to get bored with it. We give him the wet y/d food once a day to switch it up.

Thyroid levels are in normal range My senior female cat did not do well on the thyroid oral medication. She had bad side effects. The radioactive iodine therapy is extremely expensive and not an option either. But I'm happy to say that after being on this diet for 3+ months, her thyroid levels have returned to the normal range. She eats the wet and dry Y/D. She's gained a few pounds back and her spirits are up. Her coat is shiny and soft and she even plays again. This food is expensive so I downloaded some coupons to offset the price. I'd recommend both the dry and wet y/d. It works! July 24, 2014
It really works My hyper thyroid cat had been in a shelter for weeks: seemed ok and pretty mellow but, eventually -- after some bizarre behavior and then some tests--turns out he is hyperthyroid. The kibbless are all he gets because he doesn't like the canned food. My second cat is not hyperthyroid but the vet says it's OK for her to eat the same thing and she's thriving. The problem is finding it in a store-- THAT'S WHY I ORDER ONLINE WITH YOU! great service,, pleasant and knowledgeable agents. Thank you July 9, 2014
