Is white gardenia safe for cats and dogs?
Mildly. The ASPCA flags white gardenia 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. The ASPCA lists Gardenia (as Gardenia jasminoides / Cape Jasmine) as toxic to dogs, cats, and horses, with toxic principles genioposide and gardenoside causing mild vomiting, diarrhoea, and hives. G. thunbergia belongs to the same genus and contains the same iridoid glycosides; treat it as equivalently toxic. Keep away from pets and livestock.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
