What breed is my cat?

What breed is my cat? She has short silky black hair and medium size round yellow/green eyes. She is of small build and is about 4-5 lbs. She vocalizes sometimes (when about to be feed or after I come home from work/school/a trip) and sometimes when meowed at, but infrequently. She is very agile, graceul and athletic. She love to watch birds and attemp to hunt them. She is sit with you and snuggle and enjoys affection, but is also independent. I really want to know what breed she is! Thanks!
