Abstract
Pups of the altricial species, Mesocricetus auratus, are born with little metabolic capacity for heat production (Hissa, 1968). Fortunately, they are endowed with a well developed mechanism for thermotaxis (Leonard, 1974). They orient and locomote toward the warm side of weak thermal gradients, becoming quiescent when their temperature starts to rise. This behavior presumably keeps them in the nest, close to their mother, an important source of heat. In an experimental situation (Leonard, 1982) young pups prefer contact with the warm end to huddling together with littermates. This is adaptive since their littermates are exothermic and do not provide an adequate source of heat.
