I saw this a few days ago and it made me giggle. I'm reading it thinking, So this hamster is the size of a Syrian... its parents were Syrians... and the last few generations were all Syrians....... Do you think maybe, just possibly, that there is a small chance it's a Syrian hamster?
Bless them though the ad does say the alleged dwarf x syrian breeding wasn't done by them so they have obviously been either lied to, conned or some numpty thought one of their hamsters was a dwarf. It's just a shame that the next owner might think the same!
