Research on quolls suggests that the marsupials can be trained to steer clear of cane toads. Feed them toad “sausages” laced with an emetic, and they will associate toads with nausea and learn to avoid them. Detox toads, according to Tizard, would make an even better training tool: “If they’re eaten by a predator, the predator will get sick but not die, and it will go, ‘I’m never eating a toad again.’ ”
