Yes, bloodroot is toxic to cats. Its red sap and all plant parts contain sanguinarine, an alkaloid that irritates the mouth and digestive tract.

Also known as: Red Puccoon, Red Root, Sanguinaria canadensis · Sanguinaria canadensis

What makes it toxic

Sanguinarine and related isoquinoline alkaloids concentrated in the rhizome and the orange-red latex. They damage tissue on contact and irritate the stomach and intestines when swallowed.

Warning signs to watch for

Drooling, pawing at the mouth, vomiting, diarrhea, loss of appetite and lethargy within a few hours. Skin contact with the sap can cause redness and blistering that the cat spreads by grooming.

What to do if your cat eats it

Rinse the cat’s mouth and any sap off the fur with lukewarm water. Remove plant material and call your vet for guidance, especially if vomiting is repeated or the cat seems depressed.

Common questions

Is bloodroot used in medicine safe around cats?

No. Bloodroot extracts (sanguinarine) are used in some human salve products, but they are caustic. Keep supplements, salves and the raw plant all away from pets.

Which part of bloodroot is most toxic?

The underground rhizome has the highest alkaloid concentration, but leaves, stems and the sap are all irritating. No part of the plant is considered safe.
