Sultana is the Queen of the house... fierce protector, always ready to swiftly deliver justice and maintain balance in the household. She is our respected Alpha Queen whose combination of loyalty, dignity and intelligence remains unparalleled. She is the teacher of the other members of the house, and her number one student is Raja, whom she has trained in many activities such as guarding the house and acting as my alarm clock (a job which once was hers, but now she likes to sleep in).
She can also be sweet and affectionate, but also in a way that demands respect.
I suspect that Sultana is the reincarnation of a great ruler in history...or at least a strong head of household.
