If you can't get one of those cat fountains in Chile, perhaps you can find one of those little Feng Shui
fountains that sit on a table? Maybe you'll be able to change the flow of energy in a room as well?
Just make sure you completely change the water every day. I don't know about Chile but I use water from a Brita filter as the tap water has chlorine in it. I don't like the taste and I don't like my cats to drink it either.
