Is Foxglove Toxic to Cats?
Also known as: Digitalis, Fairy Bells, Fairy Gloves, Purple Foxglove · Digitalis purpurea
What makes it toxic
Cardiac glycosides — digoxin and digitoxin-like compounds — in leaves, flowers, seeds and stems. They directly disturb heart conduction and can cause fatal arrhythmias.
Warning signs to watch for
Drooling, vomiting and diarrhea first, then lethargy, weakness, dilated pupils, slow or irregular heartbeat, tremors and collapse, sometimes within hours.
What to do if your cat eats it
This is a drop-everything emergency. Go to a vet or animal ER immediately with a plant sample. Heart monitoring, decontamination and digoxin-specific therapy save lives when started early.
Common questions
Can one foxglove leaf kill a cat?
It genuinely can. A cat’s body mass and the potency of digitalis glycosides mean even small ingestions can be fatal without treatment.
Is dried foxglove in arrangements still toxic?
Yes — dried and cut flowers retain their glycosides, as does vase water. Keep all forms away from cats.
Do seeds matter?
Seeds are among the most concentrated parts. A cat nosing around spent flower spikes can ingest a dangerous dose.
