Orange Mint
Mentha citrata
Orange Mint (Mentha x piperita f. citrata), a citrus-scented hybrid mint variety, is mildly toxic to cats. Like all Mentha species, it contains pulegone and menthol-related terpenoid compounds that cats cannot efficiently metabolise. While the orange-citrus fragrance may attract some cats, ingestion causes gastrointestinal upset.
Important Notes
Toxic compounds: pulegone, linalool, and citrus-scented monoterpenoids; concentration increases in the flowers and essential oil
Mechanism: cats lack efficient glucuronidation for these terpenoids, leading to GI irritation and mild hepatic stress with repeated exposure
Symptoms: vomiting, diarrhea, drooling, lethargy; typically mild and self-limiting
Fresh leaf nibbling usually causes only transient mild upset; essential oil forms are far more dangerous
Keep mint plants and all mint-derived essential oils away from cats

Gastrointestinal · Rapidly shortly after ingestion
Lethargy, profound weakness, uncoordinated gait (ataxia), muscle tremors, and seizures
