Oooh, where to start.
That thing she does where she wants to be let out at the back door but it's raining so she'll hover half in and half out (so you can't shut it on her) for a few minutes whilst you freeze and rain is blowing in until she decides she'd rather stay in. Then she goes to the front door and annoys me until I open that one for her to have a look too. I normally lose patience there unless she only looks for a second or two and boot her out. When I'm in a good mood she's actually gone back to the back door.
When she sits on the back of the sofa and whenever I move my head she attacks my hair.
When she wants to sit on absolutely anything that it looks like I'm interested in or trying to use or read eg. newspapers, computer keyboard, book, jigsaw puzzle, work desk...
When we make a space between us for her to sit on the sofa and she decides to try and squeeze into a tiny space that wasn't intended for her. From there she gradually moves us away by pushing her feet with claws out into her legs until she ends up with half the sofa to herself.
When it's absolutely pouring down with rain, horrible dark cold weather, really windy and just awful and I'm standing at the door looking for my 'poor' cat to let her in. Usually ends up with me wet and absolutely freezing and then she'll turn up as soon as the rain finishes dry as a bone.
The worst thing is that I think all cats do all of this...
