display custom taxonomy column on custom post add new page (4 posts)

    Would someone be able to tell me where I am going wrong. I am trying to get the custom category 'Cat Breed' to display in the Add New column of a custom post I created called 'Kittens'.

    I can get the new column heading to display but the actual categories wont display when assigned to a post. I have tried a few different ways of doing this and each time get the same result - column heading displays fine but actual category types such as Long Hair, Short Hair etc that I apply to a post wont show. NOTE: Just test names at the moment till I figure out the code!

    Here is the code I have used for just this part:

    add_filter("manage_edit-kittens_columns", "add_new_kitten_columns");
    add_action("manage_kitten_custom_column",  "kitten_custom_columns");
    
    function add_new_kitten_columns($defaults) {
        $defaults['cat_breed_cats'] = __('Cat Breed');
        return $defaults;
    }
    function kitten_custom_columns( $column_name, $post_id ) {
        if( $column_name == 'cat_breed_cats' ) {
            $_taxonomy = 'cat-breed';
            $terms = get_the_terms( $post_id, $_taxonomy );
            if ( !empty( $terms ) ) {
                $out = array();
                foreach ( $terms as $c )
                    $out[] = "<a href='edit-tags.php?action=edit&taxonomy=$_taxonomy&post_type=kittens&tag_ID={$c->term_id}'> " . esc_html(sanitize_term_field('name', $c->name, $c->term_id, 'category', 'display')) . "</a>";
                echo join( ', ', $out );
            }
            else {
                _e('Uncategorized');
            }
        }
    }

    And here is the complete code:

    // kitten post type
    add_action('init', 'post_type_kittens');
    function post_type_kittens() {
    register_post_type('kittens',
        array(
            'description' => __('Create a kitten.'),
            'label' => __('Kittens'),
            'supports' => array ('title', 'editor', 'thumbnail', 'excerpt', 'custom-fields'),
            'register_meta_box_cb' => 'add_kittens_metaboxes',
            'public' => true,
            'show_ui' => true));
    register_taxonomy_for_object_type('cat_breed', 'kittens');
    register_taxonomy_for_object_type('litter_types', 'kittens');
    }                
    
    // Custom Taxonomy Code
    add_action( 'init', 'create_kittens_tax', 0 );
    
    function create_kittens_tax() {
    register_taxonomy( 'cat_breed', 'post',
        array(
            'hierarchical' => true,

    Thanks so much - have spent the past two days trying to figure this out and am at a total loss as to where to look next.
