Ingredient versus product
An ingredient is one component; a product is the actual combination and form being considered. FDA's xylitol examples show why a food category such as nut butter does not establish a particular product's ingredients. Our wording is for reading questions, not a complete legal label definition or product test.
Toxicity versus obstruction
Toxicity concerns harmful effects of a substance. Obstruction is a blockage that a swallowed object can cause. FDA discusses both, including obstruction examples such as cobs and bones. Neither term provides a home diagnosis. The absence of one type of hazard does not establish the absence of the other.
Known versus estimated versus unknown
Known means supported by information you actually have. Estimated means uncertain rather than measured. Unknown means not established. These labels keep a handoff honest; they do not calculate severity. No combination of notebook entries clears an animal or substitutes for professional advice after a suspected dangerous ingestion.
Preventive question versus suspected exposure
A preventive question asks before an item is offered. Suspected exposure concerns something that may already have happened. FDA advises prompt veterinary or poison-center contact for potentially dangerous ingestion. Do not treat the two situations as equivalent, and do not delay a current concern to finish a routine planning tool.
