Is crown vetch safe for cats and dogs?
Not entirely — crown vetch is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's 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. Coronilla varia contains nitro-glycosides (coronillin and related compounds) that are documented as toxic to horses (causing ataxia and respiratory distress) and potentially harmful to other grazing animals. The ASPCA does not list it specifically for cats/dogs, but given its documented toxicity in mammals via glycoside content, it is classified as mildly-toxic as a precaution. Seek veterinary advice if a pet ingests significant amounts.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
