"1) Animal foods do not meet the definition of a new animal drug (indeed, they are not drugs).
2) The container labels for Prescription Diets (notice the caps) do not include the federal legend required by the FDA for prescription drugs (i.e., they have not been approved by the FDA as safe and effective for their labeled indication)
The concept of a “prescription only” diet has merely been a marketing success for pet food companies who label their products as such and somehow manage to have engendered a belief that a product labeled as a “Prescription Diet”...requires a prescription.
But this is NOT TRUE! There is no legal basis for requiring a prescription for a product that is NOT regulated by the FDA as a drug. Shall I repeat that or was it sufficiently clear?"
I have a prescription for a/d hanging on my refrigerator at the moment. Huh!
