What do you do when your cat won't listen to you?

I'll usually begin with a "tktktktktktktk" sort of noise, to get her attention. Usually, that's enough to get her attention and cause her to come over. But if it doesn't, then I'll start with a hiss. If that doesn't work, I'll call with a "Come here kikikikikikikikiki", while patting my leg. Of course, her, being a cat, won't always come over, so sometimes I'll just have to go over there, grab her, and then scratch her or take her out.
