what am I missing in this simple jquery?
<p>what am I missing here: </p>

<pre><code>$(document).ready(function(){   
    $('cat_image_table').on("mouseenter", function(){
        $(this).fadeOut();
    });
});
</code></pre>

<p>Clearly something because it is not working.. Seems to be so simple yet so wrong..</p>
