it sounds to me like all your new kitty needs is some TLC....

GIve him/her some time to adjust to you and your behaivor and she will fall madly in love with you and stop all this behivor... If is has been abused in the past it will take some time.. sometimes weeks ok.

just love it and cuddle it and do what you have been doing. ok.

and eat something besides junk food.. ( I should nto talk that is all i have had to eat today too.. )
