She's a one year old Tortie
She's never liked close contact e.g being held or on your laptop but she's always been near and affectionate in her own way.
Recently she's been much more aloof, hardly ever in the same room and actually aggressive - biting and clawing at the kids.
I have three children, well four including the cat! I've always been vigilant about them being gentle with her and as we got her as a tiny kitten, she's been used to noise and a bit of chaos.
I'm not sure what's wrong but she has changed. When I go to stroke her, she cowers away 
She just looks less happy if you know what I mean?
