the adjustment of calomys callosus (rodentia, cricetidae) to intermittent food deprivation was investigated. animals subjected either to 24-hr or to 48-hr repeated periods of deprivation successfully compensated, showing (1) increases in post-fast intake relatively to the intake by control animals; (2) rapid recovery of the baseline levels of body wieght. the regulatory ability of c. callosus is comparable, in such respects, to the ability of the common rat and some other rodents but it is remarkably different from the hamster's.
