  • Feeding Guide

    How to adjust feeding amounts to maintain optimal weight.

    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. Monitoring your patient's condition will assure the nutritional recommendation provides the best results.

    • Reinforce with clients to feed Prescription Diet dry and/or canned food.
    • Gradually transition to the new food over a 7 day period.
