Thank you all for the replies!
It does explain a lot of her behaviour. She defo wasn't your laid back 'man ham.'
As for names... I'm just calling her Missy for Miss P when I talk to her. It's like a 'hello little Miss P' or 'Hey Missy' so no names really yet.
I am furious at myself for not catching on quicker! And I probably wouldn't of if I hadn't seen ErinsAnimals video on how she messed up.
