Prescription Diet™ y/d™ Feline is a complete dietetic pet food for adult cats for reduction of iodine levels in feed in case of hyperthyroidism. This dietetic pet food contains restricted level of iodine.
IMPORTANT
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 pet's 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 pet's condition.
