Is 'scarlet runner' bean safe for cats and dogs?
Use caution. 'Scarlet Runner' Bean is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't 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 on the ASPCA toxic plant database, so genus status is uncertain; treat with caution and verify with a vet. Importantly, raw runner beans and seeds contain lectins (phytohaemagglutinin) and are not safe for pets or people to eat uncooked, causing vomiting and digestive upset. Cooked beans are the edible form; keep raw pods and dried seeds away from pets.
