Toxic component and mechanism
The toxic component in Coontie Palm is cycasin.
What makes this plant different
Sago Palm is equally dangerous to cats and dogs, but cats are more likely to develop fulminant hepatic failure from a proportionally smaller dose. The seeds contain the highest concentration of cycasin and are also the most palatable part of the plant — the opposite of the safety pattern seen in many other toxic plants where leaves are riskiest.
