thanks sinicker and perseus!
after looking at some photos of roborovskii hamsters and syrian
ones, i think that rodent must be a roborovskii hamster, because
it's round and chubby like them, whereas the syrian ones are longer
in their body and not so round.
by the way, a full grown roborovskii hamster is how large?
can fit into your palm and still got room for it right? if yes,
then it must be the one i'm talking about.
but got this roboroskii website says " The smallest,
fastest and cutest of dwarf hamsters. Easily recognizable by their
light brown coat, white underbellies and endearing white
"eyebrows".
the one i saw has grey shades of fur(from dark grey to light grey
all around), not brown. got any other type of dwarf hamsters
anot?
also, how come their life so short one? i thought at least 3 - 5
years?
1 - 2 years very short leh. 
thanks,
nikar.
