Following is my categories page. It’s listing the all categories in the page.
But when gets blank value here. see the attached screen shot.
Why href is blank here

 li><a href="<?php echo esc_url(   $category_link ); ?>"><?php echo $cat- >name; ?></a></li>

Here the the complete code

<? php
    Template Name: Categories
        $cats =  get_categories();
        $num_cats  = wp_count_terms('category'); 
        $count = $num_cats;  // Total Categories
        $linetotal=round($count/3); // Part of Category
        $cat1 = get_query_var('cat');
        $category_link = get_category_link( $cat1 );    
        <!-- Main body section begins -->   
    <div class="row">   
      <div class="medium-4 large-4 columns category_list">
          $totalcount = 1;
          $totalpart = 1;
          foreach($cats as $cat): ?>
            <li><a href="<?php echo esc_url( $category_link ); ?>"><?php echo $cat->name; ?></a></li>
            if($totalcount % $linetotal == 0 && $totalpart < 3) { 
              echo '</ul></div><div class="medium-4 large-4 columns category_list"><ul>';
    <?PHP get_footer(); ?>

Any suggestions will be appreciated.
