Don't be so sure big guy that you can take care of yourself with a cat. A cougar/mountain lion/Florida panther are capable of killing an animal 6 times their size in body weight. I have heard of a few attacks here in the NW and it seems a majority are male juveniles. Its seems the older cats (as long as food source is availiable) will be more recluseive and not near as bold. It would be a freaky thing for you to be attacked by a cat but the chances are there and since you are in their yard, I would show them the respect. Later.
