=head1 EXPORTS

by default this package exports some methods for playing with your 
kitties.

=head2 milk - give milk to a kitty.

if not called directly on a kitty, $_ will be checked for a kitty;

=cut

our @EXPORT    = qw(&milk &nip);   # afunc is a function
# @EXPORT_OK = qw(&%hash *typeglob); # explicit prefix on &bfunc

sub milk {
    my $kitty;

    if(not @_ and ref $_ eq __PACKAGE__){
        $kitty = $_
    }
    if( @_ ){ $kitty = shift }

    $kitty->feed( 'milk' );
}

=head2 nip - give nip to a kitty.

if not called directly on a kitty, $_ will be checked for a kitty;

=cut
sub nip {

    my $kitty;

    if(not @_ and ref $_ eq __PACKAGE__){
        $kitty = $_
    }
    if( @_ ){ $kitty = shift }

    $kitty->feed( 'nip' );

}


=head2 is_sleeping

This method will tell you if your kitty is having a cat nap.
Kittens may be very cranky during their nap time, and waking them may be a bad
idea.

=cut
sub is_sleeping {

    my($kitty) =@_;
    0; #TODO: our kitties are currently insomniacs
}

=head2 _kitty_status

private 

=cut
sub _kitty_status {

    my($kitty) =@_;
    return 'zZzZ' if $kitty->is_sleeping();
    $kitty->{'<3'} > 5 ? '=-_-=' : '=^_^=';

}
