peppermint
Peppermint leaf freshens treat marketing more than breath. The leaf is fine; concentrated peppermint OIL is a different substance and a real feline hazard.
Also appears on labels as: peppermint leaf · dried peppermint · mentha piperita
What it is
Dried peppermint leaf. In treats it flavors "dental" and "fresh breath" products; the menthol note reads clean to humans, which is the actual mechanism — bad pet breath usually signals dental disease, which no herb addresses.
Why it's in pet food
Breath-adjacent marketing and palatability contrast. The species-level fact that matters lives one concentration step away: peppermint ESSENTIAL OIL — like most concentrated essential oils — is genuinely hazardous to cats (they lack the liver conjugation pathways to clear it), and oil-based 'freshening' products deserve scrutiny the dried leaf doesn't.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Neutral in the engine: no bonus, no deduction, no flag for the leaf as an ingredient. Persistent bad breath is a veterinary dental exam, not a mint purchase — the guide pages say it and this page repeats it, because masking the smell of periodontal disease is the opposite of a favor.
For cats
Dried leaf in a treat is a non-event; concentrated peppermint oil (diffusers, drops, oil-treated toys) is the feline hazard — cats clear essential oils poorly, and exposure is worth a vet call.
