Why is it safe?
Carrier oils are the fatty vegetable or nut oils used to dilute essential oils in aromatherapy, they are not essential oils. Fractionated coconut oil, jojoba, and sweet almond oil contain no aromatic terpene compounds and are not metabolized via the glucuronidation pathway that fails in cats. They pose no hepatotoxic or neurotoxic risk. ASPCA does not list these oils as toxic to cats. Small incidental ingestion causes at most mild GI upset from the fat content.
Symptoms
None from incidental contact or small ingestion. Significant ingestion: loose stools or vomiting from high fat content.
What To Do
No action needed for normal contact or minor ingestion.
Notes
This entry exists to draw a critical distinction: carrier oils are safe; essential oils are not. When used in aromatherapy, the carrier oil is the delivery medium, the risk in any blend comes entirely from the essential oil components it carries, not the carrier itself. A blend of lavender essential oil in coconut oil carrier is not "safer coconut oil", it is a lavender oil delivery vehicle. Never assume dilution in a carrier oil eliminates essential oil risk for cats, it reduces concentration but does not change the fundamental metabolic problem. There is no confirmed safe essential oil for cats. The safest approach is no diffuser use in cat-occupied enclosed spaces and no topical application of any essential oil product to cats.
