hamster (n.)

c. 1600, from German Hamster, from Middle High German hamastra "hamster," probably from Old Church Slavonic chomestoru "hamster" (the animal is native to southeastern Europe), which is perhaps a blend of Russian chomiak "hamster," and Lithuanian staras "ground squirrel." The older English name for it was German rat.

Bufo (n.)

toad genus, from Latin bufo "a toad," apparently also in Virgil "a hamster," a loan-word from Osco-Umbrian or another Italic dialect. Perhaps from PIE *gwebh-, a root denoting sliminess and also forming words for "frog" (source also of Old Prussian gabawo "toad," Old Church Slavonic žaba "frog," Middle Low German kwappe "tadpole," German Quappe). But de Vaan doubts the connection and suggests the basic sense might be "small creeping animal."
