Perl has at least ~~seven~~ eight cats without leaving the core or shelling out. And I'm sure I'm missing more than I identified.

$new = $string_a . $string_b; #              1 cat.
$new = join '', $string_a, $string_b; #      2 cats.
$new = "$string_a$string_b"; #               3 cats.
$new = pack '(A*)*', $string_a, $string_b; # 4 cats.
$new .= $_ for $string_a, $string_b; #       5 cats.
$new = do {
  open my $fh, '>', \my $var;
  print {$fh} $string_a, $string_b;
  close $fh;
  $var;
}; #                                         6 cats.
$new = List::Util::reduce { $a .= $b } $string_a, $string_b; # 7 cats.
$new = sprintf '%s%s', $string_a, $string_b; # 8 cats.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
