Is Cuban Oregano Toxic to Cats?
Also known as: Mexican Mint, Spanish Thyme, Indian Borage, Coleus amboinicus · Plectranthus amboinicus (Coleus amboinicus)
What makes it toxic
Concentrated essential oils (carvacrol, thymol and related monoterpenes) in the fleshy leaves. They irritate mucous membranes and the GI tract in amounts a cat can readily chew.
Warning signs to watch for
Drooling, mouth irritation, vomiting and diarrhea within hours; the strong oils can also cause sneezing or mild skin irritation.
What to do if your cat eats it
Remove the plant, rinse the mouth and offer water. Call your vet if vomiting or diarrhea persists beyond a day.
Common questions
Is Cuban oregano the same as regular kitchen oregano?
No. It is a Plectranthus (mint-family succulent) that only smells like oregano. Culinary oregano is a different plant, though neither belongs in a cat’s diet.
My cat sniffed the herb pot and sneezed — is that poisoning?
No, just a reaction to the pungent oils. Poisoning requires chewing or eating the leaves.
