How to match hash values

Limo has asked for the wisdom of the Perl Monks concerning the following question:

I have a hash that contains multiple keys with the same value:

my %hash = (cat => animal,
           (dog => animal,
           (bird => animal,
           (rose => flower,
           (tulip => flower)

I need to print a summary, based upon key value:

animal:
=========
cat
dog
bird

flower
======
rose
tulip
[download]

How would I go about doing this?
