How to got all object from laravel eloquent relationship

I'm really confusing with Laravel something really crazy as the below data format after return from below function

if($action === 'edit'){
  $cat = Cat::find($this->request->segment(3))->CategoryDescriptions;
}
dd($cat);



Collection {#340 ▼
  #items: array:2 [▼
    0 => CategoryDescriptions {#341 ▼
      #table: "ab_category_descriptions"
      #connection: null
      #primaryKey: "id"
      #keyType: "int"
      #perPage: 15
      +incrementing: true
      +timestamps: true
      #attributes: array:8 [▼
        "id" => "43"
        "language_id" => "1"
        "name" => "Skincare"
        "meta_keywords" => ""
        "meta_description" => ""
        "description" => """
          <p>\n
          \tProducts from award-winning skin care brands</p>\n
          """
        "updated_at" => "0000-00-00 00:00:00"
        "created_at" => "0000-00-00 00:00:00"
      ]
      #original: array:8 [▶]

    }
    1 => CategoryDescriptions {#342 ▼
