RSS as a measure of crystal and stone potential

The abstract describes RSS as a measurement that estimates the potential for crystal formation and bladder stone growth, which it calls a common affliction in cats. The draft guidance provides recommendations for how pet food manufacturers can use RSS methodology to substantiate general structure or function claims. Specifically, the claims would state that an adult maintenance cat food supports urinary tract health by promoting a healthy mineral content in the urinary tract.

Informational rendition, not the legal edition

The supplied text states that this web/API rendition is an informational resource, not the official legal edition. It advises verifying the linked official PDF on GovInfo and applicable later amendments before relying on legal requirements.

How to interpret this

Document summary; not a determination of current law. Based only on the agency abstract and metadata; the full draft guidance was not reviewed. The web rendition is informational, not the official legal edition; a notice is not a final rule, and a publication date is not necessarily an effective date.

Based on the cited official document. Its jurisdiction, document type and effective date matter; a proposal or notice is not a rule already in force.
