this has to be done in template toolkit alone!
Ok, well, I thought I'd be clever and work up a hack for you and I found a TT
bug which makes it ineffective. It appears the split vmethod does not work
correctly with args. I'll fire off a new email to the mailing list to notify
Andy of this.
Anyhow, you can technically do this search and replace by using .match and .split.
(Probably not very efficient, but it gets the job done.) Here is the hack I wrote up.
Note that I use the "split2" virtual method below which is the fixed version of
the internal split vmethod. (Note, this can probably optimized a bit, but I don't have
all day to work on this.) :)

[% t = 'catdog fooo catdog bar abcd asdfkj CatDog akdjd catDog abc CATDOG' %]

Here's the split2 vmethod for those interested:
$Template::Stash::SCALAR_OPS->{ split2 } =
sub {
my ($str, $split, @args) = @_;
$str = '' unless defined $str;
return [ defined $split ? split($split, $str, $args[0])
: split(' ', $str, $args[0]) ];
};
