       Cat thor = new Cat();
       Cat rambo = new Cat();

       thor.name = "Thor";
       thor.age = 3;
       thor.breed = "Russian Blue";
       thor.color = "Brown";

       thor.sleep();

       /*
       Defining Rambo cat

       rambo.name = "Rambo";
       rambo.age = 4;
       rambo.breed = "Maine Coon";
       rambo.color = "Brown";
