our lovely dwarf russian has had more hamster pups today! her first litter are only 3 wks old 
the first litter were a total suprise because we thought that we had 2 boys
so we moved Dad out the same day that we found them (they were a few days old)
she has become pregnant again immediately, i know they are only pregnant for 18-21 days and we suspected she was pregnant this time because she got fatter 
we have gone from one hamster cage to three ....... aaarrgghhhh
BUT the pups are as cute as can be
