My cats aren't spoiled, but they still tend to do what they want. It's just that the things we try to discourage them from doing, they do when we aren't looking -- like jumping onto the counter. My cat would like the others to leave for good and she won't be happy until they do. She just wants to be with me all day.
The other two are my son's cats. The older one sleeps on whatever sewing project(s) I have on my table. I finally gave up trying to get her to stay off. The little one plays with spools of thread and even straight pins, buttons, sequins -- any thing she can toss or spill.
