I'm new as a cat owner and one problem is my cat allways comes up to me wanting to be petted but when I reach down to pet him he starts to lash at me with his paw. He don't claw me but he acts like he is going to and he acts like he is going to bite me too. Another thing is he will get real wired up and if I walk into a room he will crouch down like I'm a danger to him and then bolt out of the room then a minute later he will approach me wanting petted like nothing happened. Any clues to this puzzling behavior would be appreciated.
