Is Dutchman’s Breeches Toxic to Cats?
Also known as: Dicentra cucullaria, Bleeding Heart (wild) · Dicentra cucullaria
What makes it toxic
Isoquinoline alkaloids (including canadine-type compounds) concentrated in the roots and foliage. They overstimulate then depress the nervous system and irritate the digestive tract.
Warning signs to watch for
Drooling, vomiting and loss of appetite within hours. Bigger ingestions can progress to trembling, staggering, muscle twitching and seizures.
What to do if your cat eats it
Remove plant material, rinse the mouth and call your vet the same day. Any tremor, staggering or seizure means an immediate emergency clinic trip.
Common questions
How dangerous are the roots compared to the flowers?
The bulblets and roots hold the highest alkaloid concentration — historically they poisoned grazing animals that dug them up. Flowers and leaves are less potent but still toxic.
Is this the same plant as garden bleeding heart?
It is a wild relative (Dicentra cucullaria) with the same toxic alkaloid profile, so treat both alike around pets.
