Simple inheritance with functions in subclasses [closed]

It seems like there are many ways implementing inheritance in JavaScript. Which version do you prefer or would you suggest another solution?

The code should run in IE8+ so my first version would not fit…

function Animal(name) {
    this.name = name
}
Animal.prototype = {
    eat: function() {
        console.log(this.name + ': *eat*')
    }
}

function Cat(name) {
    Animal.call(this, name);
}
Cat.prototype = Object.create(Animal.prototype, {
    miaou: {
        value: function() {
            console.log(this.name + ': *miaou*')
        }
    }
})

var garfield = new Cat("Garfield");
garfield.eat();     // Garfield: *eat*
garfield.miaou();   // Garfield: *miaou*


// ------------
//
// possible alternative:

// […] see http://ejohn.org/blog/simple-javascript-inheritance/ for definition
// of Class

var Animal2 = Class.extend({
    init: function(name) {
        this.name = name
    },
    eat: function() {
        console.log(this.name + ': *eat*')
    }
});

var Cat2 = Animal2.extend({
    init: function(name) {
        this._super(name)
    },
    miaou: function() {
        console.log(this.name + ': *miaou*')
    }
});

var garfield2 = new Cat("Garfield2");
garfield2.eat();        // Garfield: *eat*
garfield2.miaou();      // Garfield: *miaou*
