Laravel not finding the App\Auth from model

I'm using Laravel 5.5 and am reading up a bit on morphToMany relationships.

My naming for this model is a bit odd, but please bare with me.

I have a Drool model, and im building a getIsDrooledAttribute function.

The function which is returning errors is the following;

$drool = $this->drools()->whereUserId(Auth::id())->first();
return (!is_null($drool)) ? true : false;

and the error im getting is

Class 'App\Auth' not found

I am running the standard auth system created when running php artisan make:auth

Any help would be greatly appreciated.
