I have three male cats and two of them can get very jealous. Sunny gets very jealous and meows loudly and then runs over to me when I am giving either Storm or Pepper any kind of attention. He'll do it even after I've given him attention first. It seems like he has to always be the center of attention. He is the baby. Storm will stare and glare at me while I'm giving the other two attention. When he can't stand it anymore, he'll come running over to me and demand attention. Sometimes I think that Pepper gets the least attention because he's so laid back and not as demanding as the other two.
