How to adjust feeding amounts to maintain optimal weight.
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:
- Gradually transition to your pet's new food over a 7 day period.
- Exclusively feed the recommended Prescription Diet dry and/or canned food.
- Keep fresh water available at all times.
- Have your veterinarian monitor your pet's condition.
- To prevent suffocation, keep the packaging out of the reach of pets and children
