Is black-eyed susan vine safe for cats and dogs?
Mildly. The ASPCA flags black-eyed susan vine as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. 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. Thunbergia alata is not individually listed on the ASPCA toxic or non-toxic plant database, and no Thunbergia species appears on it, so the genus cannot be confirmed safe. Some pet-toxicity references note possible mild gastrointestinal upset if chewed; treat as mildly toxic and verify with your vet before assuming it is pet-safe. Note this is the vine, not the unrelated Rudbeckia hirta also called black-eyed Susan.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
