foreach (@animals) { $animals{$_}++; }  # initialize %animals hash

Here's a faster way to do that (looks neat too): 
@animals{@animals} = (1) x @animals;

It's not exactly the same since it's setting each hash member to 1 instead of ++'ing it, but that's no big deal if you're just checking for an element's existance.
