Although the Syrian hamster

hamsterThe intact laboratory and pet populations of Syrian hamsters appear to be descendants of a only brother-sister pairing. These littermates be captured and marketing in 1930 from Aleppo by Israel Aharoni
hamster, a zoologist of the University of Jerusalem.
hamsterIn Jerusalem, the hamsters bred very successfully. Years later, animals of this archetypal breeding colony be marketing to the USA, where Syrian hamsters became one of the most favorite pets and laboratory animals. Comparative studies of domestic and wild Syrian hamsters have shown reduced heritable variability in the domestic strain. However, the differences in behavioral, chronobiological, morphometrical, hematological, and biochemical parameters are relatively atomic and fall into the expected range of interstrain variations in other laboratory animals.

Female taiwanese and Syrian hamsters are characterized for being battleful toward the antheral if kept together for too desire aft mating.
