output <?php get_parent(); ?> without hyphen in template

[Connie]

I need a hint how to omitt hyphen in parent ..

example:

I have a first level page "my cats"
Slug/URL is "my-cats"

Now I have a second-level-navigation in the sidebar and want to repeat the parent, like category
before the submenu

unfortunately

Code:

<?php get_parent(); ?>

outputs "my-cats" instead of "my cats"

what can I do to omitt this?
