[Help Wordpress] Category.php

Category.php

But I use one code for all my categories.
Like this, in my category.php:
  $category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;
   $the_query = new WP_Query(array(
    'cat' => $cat_id,
    'posts_per_page' => 5 ,
    'offset' => 1
    ));
   while ( $the_query->have_posts() ) :
   $the_query->the_post();
  ?>

With this tutorial, I need to create a lot of slider, select the category one-by-one. But I need only one slider to get the category of page...
