Is pink evening primrose safe for cats and dogs?

Not entirely — pink evening primrose 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. Oenothera is not individually listed on the ASPCA toxic or non-toxic plant lists. Evening primrose oil contains gamma-linolenic acid; the foliage and seeds may cause mild gastrointestinal upset if ingested in quantity by pets or children. Until a definitive ASPCA listing is available, treat with caution and prevent pets from grazing on plants.
