Is moses-in-the-cradle (oyster plant) safe for cats and dogs?
Use caution. Moses-in-the-Cradle (Oyster Plant) is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. The ASPCA does not list Tradescantia spathacea (Rhoeo) individually, but the genus is not considered safe: ASPCA lists related Tradescantia fluminensis (Inch Plant) and Tradescantia multiflora as toxic to dogs and cats, with dermatitis as the main sign. Treat it as mildly toxic, since the sap causes skin and mouth irritation and mild GI upset (drooling, vomiting) if chewed. Keep away from pets and verify with your vet if ingested.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
