Standard advice, in the event that you should be face to face with a big pussy cat, is to stand your ground, and make yourself look as large as possible (put your kids up on your shoulders,, raise your poncho up high, etc.).

If Mr. Cat is stalking you (very, very unlikely) you will probably never know what hit you. They stalk from on high, and sever the spinal cord at the neck with the first bite.

Again, attacks are very rare.
