Perfect Unison

These two cuties are sisters, and it's so funny how in sync they are.  So many times they are in the same place, and their heads turn at the same time, the ears even flick in unison.  They like being around us, so usually if they aren't in the same room as us, they are close behind and watching us.  Both of them have fallen from up here though.  And I thought cats had good balance!
