Haha, I just read this. My birds and dog delight in clean water. I take care of animals at my job and surprisingly the pigs appear to delight in a clean waterer more than any other animal, but maybe that's because they get it so dirty. My chickens actually prefer the runoff stream in my yard...
I know this is an old post, but love it! So nicely said: "Would you take a sip out of the waterer...if not, clean it". My biggest pet peeve is dirty water. Animals deserve sparkling clean water and they notice if it isn't, just like we do!
