Is wintersweet safe for cats and dogs?
Use caution. Wintersweet 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. Chimonanthus praecox is not individually listed on the ASPCA toxic or non-toxic plant database, so its safety for cats and dogs is not confirmed by that authority; treat with caution and verify with a vet. Its leaves, seeds and fruit contain the alkaloid calycanthine, documented to cause neurological signs in livestock, so keep pets from chewing the plant.
| Pet | Toxic? | Per ASPCA |
