Distilled water or regular bottled water?

[PitOnTheProwl]

I personally use SPRING bottled water. Not distilled/purified/etc. And I put my pinky out when I pour it into their water dishes.

HA, just kidding. For me, I use bottled spring water because regular tap water calcifies the water bowls, which drives me nuts and is hard to clean.

Vinegar will take it right out. I usually soak my bowls every couple months to remove the calcium buildup.
