The thing is, when we lived in Tennessee, I poured water from our Brita filter into Sully's bowl.
But, here in Charleston, our water filtration process is the same as most bottled water companies - double osmosis. So, really the water we bathe in is the same as most bottled water.......so now of course Sully drinks out of the tap, and so do we. No more need for the old Brita filter these days!
In defense of the bottled water-serving folks out there, I wouldn't serve Sully any less than I would drink myself. So, if I drink tap water, so does he, and if I drink filtered, so would he.
