I tried to post this earlier, but I'm not sure if it got through: In my first attempt at writing a module, I created a module called "my_mod.pm": 
package my_mod;

sub cat{
  print "meeow.\n";
}

1;

[download]
And called cat in a script known as "dog": 
#!/usr/bin/env perl

use my_mod;

cat();

[download]
However, it is coughing up an error, indicating "undefined subroutine &main::cat". What am I doing wrong?
