@theru It must be something Mediterranean cause in Spain is 7 lives too.
@ghostdancer I wonder where the 9 lives comes from (here that is) probably something we adopted
@theru The number seven always had "magical" connotations , 7 colours of the rainbow, 7 hills of Rome, .... and I'll make a guess that as the other "magical" number usually is the three, and nine is three times three.
