Is yardlong bean safe for cats and dogs?
Not entirely — yardlong bean 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. Not individually listed by the ASPCA, so genus status is uncertain; treat with caution and verify with a vet. As a cowpea (Vigna unguiculata), the mature dried seeds contain lectins and antinutrients and should be cooked before eating; raw beans can cause digestive upset in pets. Young cooked pods are the usual edible form. Keep dried seed away from pets.
