Abstract
The effect of eating mice over an 8-month period was observed to produce a greater response to mouse body surface extract in young rat snakes (Elaphe). Two measures, attack tongue flick and attack orientation, were employed. This finding was contrasted with earlier results indicating a wide-spectrum undifferentiated response to prey-object extracts at birth.
