Abstract
18 mouse-killing Long Evans male rats were devibrissaed and facially anesthetized to determine relative importance of facial tactual sensation in detection, pursuit, and killing behavior. With vibrissae clipped plus local anesthesia of the vibrissal pads, all rats attacked and killed mice with efficiency comparable to pretest baseline measures. Results were interpreted as indicating a nonsignificant role of vibrissal sensation in maintenance of this rodent's predatory kill response. Although initial killing may be contingent upon multiple sensory cues, established killing is independent of intact perception of the target.
