Call to undefined method App\Models\Catogry::firstItem() - laravel

Question

I'm trying to create a CMS project but I got this error when I create the URL & Controller for the edit button (Call to undefined method App\Models\Catogry::firstItem()).
here is the web.php page
<?php
use App\Http\Controllers\CategoryController;
use App\Models\User;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
return view('welcome');
});
Route::middleware(['auth:sanctum', 'verified'])->get('/dashboard', function () {
// $users = User::all();
$users = DB::table('users')->get();
return view('dashboard', compact('users'));
})->name('dashboard');
//category controller
Route::get('/category/all', [CategoryController::class, 'index'])->name('index.category');
Route::post('/category/add', [CategoryController::class, 'store'])->name('store.category');
Route::get('/category/edit/{id}', [CategoryController::class, 'edit']);
here Is the CategoryController >>
<?php
namespace App\Http\Controllers;
use App\Models\Catogry;
use Carbon\Carbon;
use Illuminate\Auth\Events\Validated;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\DB;
class CategoryController extends Controller
{
public function index()
{
$categories = Catogry::latest()->paginate(5);
return response()->view('Admin.category.index', compact('categories'));
}
public function store(Request $request)
{
$validated = $request->validate([
'category_name' => 'required|unique:catogries|max:25|min:4',
]);
//insert with three ways *****
// Catogry::insert([
// 'category_name' => $request->category_name,
// // 'user_id' => Auth::user()->id,
// 'created_at' => Carbon::now()
// ]);
$categories = new Catogry;
$categories->category_name = $request->category_name;
$categories->user_id = Auth::user()->id;
$categories->save();
// $date = array();
// $data['category_name'] = $request->category_name;
// $data['user_id'] = Auth::user()->id;
// DB::table('catogries')->insert($data);
return redirect()->back()->with('success', 'Category Inserted Successfully');
}
public function Edit($id)
{
// return 'edit page';
$categories = Catogry::findOrFail($id);
return response()->view('Admin.category.edit', compact('categories'));
}
}
here is the edit.blade.php page >>
<form action=" " method="POST">
#csrf
<div class="card-body">
<div class="form-group">
<label for="category_name">Edit Your Category Name</label>
<input type="text" class="form-control" id="category_name" name="category_name" placeholder="Enter category name"
value="{{ $categories->category_name }}">
</div>
<div class="card-footer">
<button type="submit" class="btn btn-info">Update Category</button><br>
#error('category_name')
<span class="text-danger">{{ $message }}</span>
#enderror
