# Pet

What family would be complete without a pet?

## Completed Code

```javascript
function Pet(firstName, lastName, gender, age, birthday, animal, breed, color) {
    Person.call(this, firstName, lastName, gender, age, birthday)

    this.animal = animal;
    this.breed = breed;
    this.color = color;
    this.good = function () {
        if (this.pronoun().toLowerCase() == "he") {
            return "boy";
        } else if (this.pronoun().toLowerCase() == "she") {
            return "girl";
        } else {
            return this.animal;
        }
    }
}
Pet.prototype = Object.create(Person.prototype);
Pet.prototype.constructor = Pet;

Pet.prototype.description = function () {
    return ("My " + this.animal + ", " + this.firstName + ", is the world's greatest " + this.breed + ".");
};
Pet.prototype.bday = function () {
    return ("Our " + this.color + " " + this.breed + " turns " + this.nextYear + " on " + this.birthday + ".");
};
Pet.prototype.praise = function () {
    return (this.pronoun() + " is/are " + "such a good " + this.good() + "!");
};
var pet1 = new Pet('Bon-Bon', 'Jovi', 'female', 3, 'February 14', 'dog', 'Border Collie', 'black and white');
console.log(pet1);
console.log(pet1.description());
console.log(pet1.bday());

   * `color` - what color is/are your pets fur, scales, feathers, etc?
   * `good()` - a function that we'll use to output a noun based on the gender pronoun.
2. **New Functions**
   * `description()` - displays `animal`, `firstName`, and `breed`.
   * `bday()` - displays `color`, `breed`, as well as `nextYear` and `birthday`
