Where Is That Mouse

My Cat is a pain in the ass, for some reason she think that coming into my room in the morning and trash it. I believe she is looking for a mouse, however I think her past expirence with electricity should have taught her a lesson. As last christmas Milly thought it would be a good idea to bite through the christmas tree lights when they were on, well needless to say she go the shock of her life and ended up at the other side of the room, it was funny. Don't worry she has not learnt her lesson and still bite's through my MP3 wires, computer wires etc..... the little bugger, but she is cute, with fryed wiskers and all.
