Abstract
The predatory behavior of ferrets (Putorius putorius furo L.) consists mainly of instinctive behavioral patterns that are elicited by simple external stimuli. For the ferret, the time needed to catch and kill rats depends on the size of the rats in relation to that of the ferret. Killing success decreases with a relative increase in prey size. Chlordiazepoxide hydrochloride injections (1 mg/kg, i. m.) modified this behavior. Drugged ferrets needed less time and less bites to kill relatively large rats; killing success was also increased. Chlordiazepoxide seemed to disinhibit the ferrets when they were presented with large rats, which they normally attack more cautiously.
