Is Western Columbine toxic to cats?
Aquilegia formosa
Yes — western columbine is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. All parts of Aquilegia formosa — particularly the seeds and roots — contain isoquinoline alkaloids and cyanogenic glycosides that are toxic to dogs, cats, and humans if ingested in significant quantities. Seeds are the most toxic portion. Symptoms include vomiting, diarrhoea, and in serious cases cardiac effects. The plant tastes extremely bitter, which limits voluntary ingestion by pets, but risk remains. Not individually listed on the ASPCA toxic plant list for this species, but veterinary sources consistently flag Aquilegia as toxic to pets and humans. Wear gloves when handling and keep children and pets away from plants during seeding.
