Is walking stick kale safe for cats and dogs?
Not entirely — walking stick kale 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. As a Brassica oleracea kale, it is not individually listed by the ASPCA and is generally non-toxic to dogs, but it contains N-propyl disulfide and thiocyanate/isothiocyanate compounds that can cause Heinz-body hemolytic anemia in cats and GI irritation with repeated or large feeding. Although historically fed to cattle, treat it as unsafe for cats in quantity and check with a vet before feeding pets.
