Pet Pictures are all about cute pets. And what better to make a great pet picture than babies of different pet species ? Baby ducklings are very, very cute. Small and helpless, there's something that makes you love 'em.
Unfortunately for us, ducklings grow up and become ducks. I don't have first hand experience with a pet duck and that makes me a little curious. Now that I think about it, I'm pretty traditional, all I ever had as pets were dogs, cats or the ocassional rabbit.
Oh well, there's plenty of time to experiment with different pets, and be sure you'll get some quality pet pictures from those experiments. ;)
