Fresh running water does have great appeal, even to pets. Take cats,
for example: it's the rare one who will even drink from a bowl of
"stagnant" water. And when you think about it, cats have it right...
who wants to drink out of a bowl or a glass of water that's been
sitting there for half a day or so? Perhaps that's why the latest
trend in pet drinking is not the 'pet bowl,' it's the 'pet fountain,'
where water flows constantly, or on demand.
