Never understood the dumbass pspsps thing. It's annoying and I've pretty much never seen it work. What always has worked for me is to chill just a little ways away and completely ignore them. Just as non-threatening as you can make yourself if you were a piece of furniture left out on the sidewalk.

From personal experience, cats hate being made to do things and don't come when called unless they already know you and like you a lot. But they also loathe being ignored and will snoof right over shortly to the one person being completely indifferent to them.

This would be the same reason they seem to mercilessly hunt anyone with a cat allergy. Your perceived dislike of them shall not stand!
