My name is Ruby Rose!

We adopted Ruby from a Charlotte shelter when she was 6 weeks old. She is now 4.5 years old.
In the last few months she has become aggressive, especially towards me (hissing and wanting to scratch or bite me).
She has also went after my wife and kids.
Normally she just likes to lay around like any cat. She does not like to be pet, although she loves to be brushed, especially when she is eating.
She is a strictly indoor house cat. She was never outside.
Ruby loves to rub against your legs and loves her treats.
My vet cleared her of any health issues.
I was told she would make a great barn cat or may like to convert to an outdoor cat.
