## Abstract The photorefractory period of golden hamsters is characterized by the failure of short daylengths (<12.5 hours per 24) to induce gonadal regression. Photorefractoriness is terminated by prolonged exposure to long daylengths (>12.5 hours per 24). This study was designed to determine the
Female hamsters were allowed to attack a series of target hamsters until they reached a criterion of attack satiation. Following delays of 0, 24, or 48 hr they were then presented with a novel "probe" target. Attacks on the probe target were reduced to 26% of baseline at 0 delay and had returned to
If hamster pups are placed in individual cages at weaning (21 days of age) they begin to hoard food immediately; within 2-6 days, they hoard 90% of the food they take from their food dish in the course of a 1-hr test, consuming only 10% of it. Pups that remain with their littermates after weaning in
