I have 8 cats they are all related in one way or another mom ,grandma , sisters and brothers , aunts ect and they all talk to each other all the time and to every one in the family in fact the other morning my daughter came into the kitchen and said all the cats where sitting on the counter facing each other and talking like they where ploting something . I swear they are actually communicating . maybe since the mother cat does talk to her young and all my cats are related they just kept talking ???
