Is Tradescantia toxic to cats?
Tradescantia (Tradescantia zebrina) is toxic to cats. The agent is sap irritant.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
What it does, and why
Tradescantia contains sap irritant. It acts as a direct irritant to the mouth and gut.
Signs to watch for
Contact dermatitis, itching and redness; mild stomach upset if eaten.
How likely is it, really
Most cases are a chewed leaf rather than a meal. The dose matters: a nibble and a swallowed stem are different events. Volume, and how long ago, are the two things the vet will ask.
Keeping the plant anyway
Height alone does not work with a cat — a cat treats a high shelf as a destination. What actually helps: a room the cat does not have unsupervised access to, a hanging position with no adjacent launch point, and clearing fallen leaves the same day, since a dropped leaf on the floor is the usual culprit. A pot of cat grass elsewhere in the room redirects the urge to chew far better than deterrent sprays do.
Is it toxic to people?
Yes, mildly. The same compound irritates human mouths and skin, so it is worth keeping Tradescantia out of reach of a toddler and washing your hands after pruning. Serious harm to an adult is very unlikely.

Sources and how we checked
This species is not listed under a name we could resolve in ASPCA's database, so the record above comes from standard horticultural and veterinary references and is marked unconfirmed. We do not present an unconfirmed plant as safe. The full list is at aspca.org.
This is general information, not veterinary advice. Any animal that is actually unwell needs a vet, not a web page.
