Or this way -- why bother with indexes at all? 

foreach $animal ( @{ $animals{pets} } ) {
        push ( @some_animals, $animal );
    }

    That's true. I tried it that way at first and got unexpected results (the array getting treated as 1 item when I tried to sort and make the elements unique) but it's probably because I was using qq incorrectly to populate the hash in the first place. I should have used qw and the elements would have been separate elements.
