Is silvery lupine safe for cats and dogs?
Toxic — the ASPCA lists silvery lupine as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. 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. Lupinus argenteus is toxic to dogs, cats, and horses per ASPCA guidance on the Lupinus genus. Quinolizidine alkaloids (including anagyrine and lupinine) are present throughout the plant. Seeds and pods carry the highest concentration. Livestock poisoning (cattle, sheep, horses) is well documented. Symptoms in companion animals include vomiting, weakness, labored breathing, and liver stress.
