  1. There is not a is_subcategory() function but you can get the children (sub category) of a category and use as a conditional statement.

    <?php
global $ancestor;
$childcats = get_categories('child_of=' . $cat . '&hide_empty=1');
foreach ($childcats as $childcat) {
  if (cat_is_ancestor_of($ancestor, $childcat->cat_ID) == false){
   //do stuff
  }
}
?>
