Is joseph's coat safe for cats and dogs?
Not entirely — joseph's coat 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. Amaranthus tricolor is widely eaten as a leaf vegetable by humans, but the genus Amaranthus includes A. retroflexus (pigweed), which the ASPCA lists as toxic to dogs, cats and horses due to soluble oxalates. Ornamental Amaranthus contains oxalates and nitrates that may cause gastrointestinal upset in pets with significant ingestion, and large quantities can be harmful to livestock. As a precaution, treat as mildly toxic to pets and contact a vet if ingestion is suspected.
