This is Frankenstein, or more commonly known as Frankie. This is Mouse's
cat furry soul mate. Mouse has been with Frankie since the day he was born. Once she brought him home their unity was cemented.
Frank has been there for Mouse through her struggles. He sits patiently and listens to her read him books. She tries in vain to teach him to say the alphabet. In some ways I think he's been therapeutic for her.
He is lost without her and is lost without him. When she is gone he circles her bed crying. Mouse just has to yell his name and he comes running to her.
So that is our Frankenstein.
