Because anecdotes are always meaningful :) how about another one.
My cat and dog have fairly ready access to natural type water sources 
(springs/streams and a river) but they love to drink from skanky 
puddles, cruddy old buckets, a livestock water trough (usually contains 
some algae, leaves, bits of wool), etc. The cat for some reason also 
persists in drinking water from the dog's personal indoor supply, truly 
laughing in the face of danger (the dog once gave said cat a rather 
painful bite during a misunderstanding involving his food bowl).  I 
suppose an indoor animal might appreciate a water feature, though.
