When naive rats of our colony were individually housed for 1 month with free access to laboratory chow and water as drinking fluid, 6% exhibited muricidal behavior. When naive rats of the same colony were similarly housed but received ethanol 20% in water as the sole source of drinking fluid (ll.5 g ethanol/kg/day), the percentage of killer rats was the same. However, when the rats were housed in similar conditions and submitted to a 1‐day ethanol withdrawal, the percentage of muricidal rats increased to 25%. Ethanol intake in the same conditions as described above did not change muricidal behavior of spontaneous killers and did not induce killing behavior in nonkiller animals. GABA‐mimetic agents administered IP blocked ethanol withdrawal‐induced killing behavior as well as spontaneous muricidal activity.
