Well there must surely be an error in your coding.
Make sure the the model exists in the folder (and extend CI_Model if you're using CI 2.0), give a better look at the wonderful user guide for more info, since this is a very basic thing and it should work without problems.

This problem was discussed only yesterday. Check this reply for information on the 'loading model in a model' situation.

From the provided example it doesn't look like calling a model from a model. :/

I'm sorry, I didn't read well enough. It should work as you do it.. I can't think why the model wouldn't load.
Maybe you can do a "print_r($this);" after loading the model? To see if it is loaded and what variable name it has!

me n hanburger are from the same team.
just to clarify on the code in the first post
the Test Controller class and the Category_model class are inside 2 separate files
Code:
class Test extends Controller
{
function Test()
{
parent::Controller();
}
function index()
{
$this->load->model('category_model');
$this->category_model->get(1);
}
}
/* Location: ./system/application/controllers/test.php */
-----------------------------------------------------------------------------------
class Category_model extends Model
{
function Category_model()
{
parent::Model();
}
function get($id)
{
// some function to get data from database
}
}
