Abstract
Lithium-induced prey aversions were studied in the laboratory rat and ferret. Both species acquired aversions, blocking consumption of flavored foods and the flesh of mice. In the rat, attack was also blocked when illness immediately followed mouse-killing, when mice were dipped in a strongly aversive flavor, and when illness followed killing and eating of prey dipped in an artificial flavor with strong olfactory and gustatory properties. Testing context was of some importance. The ferret, on the other hand, continued to attack, killing mice with its feet rather than with a bite to the neck. Strong footshock produced a transient inhibition of attack that was specific to the training situation. These results with laboratory species are in distinct contrast to those with wild predators.
