Bubbajuju on "Show Category Children But Hide "No Category" with Children List"

<?php
$cat_id = get_query_var('cat');
$catlist = get_categories('child_of=' . $cat_id);
if ($catlist) {
wp_list_categories('echo=0&orderby=id&title_li=&child_of=' . $cat_id);
} else {
//Now instead of "No Categories" showing I want to re-display the child categories

?>

Thanks for any help...
