Last week, I shared North's unsightly tear stain problem [1] and several users suggested offering him purified or Brita-filtered water. I'll admit, I have been offering him drinks from the tap most of the time (unless we're on an adventure, then he gets bottled). This sounded like an easy fix and I've attached a filter to my faucet so he'll be getting fresh water from now on. How many of you consistently give your pets bottled or filtered water on a day-to-day basis?
