There are more races of hamsters than I care to talk about, but some do come to my mind when we discuss our rodent friends.
The various species of hamsters found in nature today are all descendants of the African wild hamster. One reckons that the origin of the domestic hamster is found in the African wild hamster which inhabits today the savannahs of Central and Northern Africa.
Some hamsters are born with dysfunctions created by man in his pursuit of creating new races. These dysfunctions might be loss of hearing, lack of hair and teeth as well poor eye sight.
