$cat = $cat[0]->cat_ID;

of course if $cat is not empty


Essentially somewhere in that code one of function fails to do what it should and informs about that by returning object of WP_Error class.

You can use is_wp_error() to check for such returns and methods of WP_Error class to retrieve errors (and then echo them or something).
