As you can see, responses() does not return an instance of your model, rather the Response Facade. You should either rename your model or set a namespace for reference in your Ticket model.

Response.php

<?php namespace My\Models;

class Response extends \Eloquent {}

Ticket.php

<?php namespace My\Models;

class Ticket extends \Eloquent
{
    public function responses()
    {
        return $this->hasMany('My\Models\Response');
    }
}

Now $ticket->responses() returns an instance of your model.

Thanks. I tried both solutions and they both worked. However, I'm curious why at first responses() couldn't return the instance of my Response model.

Thanks.
