كيف أعالج خطأ أثناء جملة استعلام لحذف عنصر على laravel 5.1؟

حصلت على الخطأ التالي أثناء قيامي بعملية حذف بيانات على laravel 5.1، ورسالة الخطأ كالآتي:

MethodNotAllowedHttpException in RouteCollection.php line 219:
in RouteCollection.php line 219
at RouteCollection->methodNotAllowed(array('DELETE')) in RouteCollection.php line 206

رابط الحذف على التطبيق هو:

<a href="{{ url('cats/'.$cat->id.'/delete') }}">
    <span class="glyphicon glyphicon-trash"></span>
    Delete
</a>

مسار الحذف كان بهذا الشكل:

Route::delete('cats/{cat}/delete', function(Furbook\Cat $cat){
    $cat->delete();
    return redirect('cats')->withSuccess('Cat has been deleted');
});

عرض لبقية المسارات بالتطبيق:

<?php 
/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', function () {
        return redirect('cats');
});

Route::get('cats', function () {
    $cats = Furbook\Cat::All();
        return view('cats.index')->with('cats',$cats);
});

Route::get('cats/create', function(){
    return view('cats.create');
});

Route::post('cats', function(){
    $cat = Furbook\Cat::create(Input::all());
    return redirect('cats/'.$cat->id)->withSuccess('Cat has been created');
});

Route::get('cats/{id}', function ($id) {
    $cat = Furbook\Cat::findOrNew($id);
    return view('cats.show')->with('cat',$cat);
});

Route::get('cats/{cat}', function(Furbook\Cat $cat){
    return view('cats.show')->with('cat',$cat);
});

Route::delete('cats/{cat}/delete', function(Furbook\Cat $cat){
    $cat->delete();
    return redirect('cats')->withSuccess('Cat has been deleted');
});

Route::get('about', function () {
        return view('about')->with('number_of_cats',9000);
});

Route::get('cats/breeds/{name}', function ($name) {
    $breed = Furbook\Breed::with('cats')
        ->whereName($name)
        ->first();
        $cats = null;
        if(isset($breed))
                $cats=$breed->cats;
    return view('cats.index')
        ->with('breed',$breed)
        ->with('cats',$cats);
});

وبطريقة أخرى عند كتابة الأمر php artisan route:list :

+--------+----------+--------------------+------+---------+------------+
| Domain | Method   | URI                | Name | Action  | Middleware |
+--------+----------+--------------------+------+---------+------------+
|        | GET|HEAD | /                  |      | Closure |            |
|        | GET|HEAD | about              |      | Closure |            |
|        | POST     | cats               |      | Closure |            |
|        | GET|HEAD | cats               |      | Closure |            |
|        | GET|HEAD | cats/breeds/{name} |      | Closure |            |
|        | GET|HEAD | cats/create        |      | Closure |            |
|        | GET|HEAD | cats/{cat}         |      | Closure |            |
|        | DELETE   | cats/{cat}/delete  |      | Closure |            |
|        | GET|HEAD | cats/{id}          |      | Closure |            |
+--------+----------+--------------------+------+---------+------------+
