Tika is picky; she is a picky drinker and I'm delighted. If there are "floaties" in her water bowl, she looks up at me as if to say, "You expect me to drink that??" So I keep her water bowl shiny clean. Good for her.
Wish our ancestors had been so lucky with getting clean water. And because they could not, and had to drink contaminated water all too often, they suffered and died terribly and miserably from cholera. Cholera is an infection of the small intestine caused by a bacterium. Cholera's main symptoms are profuse diarrhea, vomiting and abdominal pain. A person afflicted with cholera "may produce around 10 litres of diarrhoeal fluid a day." (Wikipedia) That equates to almost 3 gallons........... 21 pints........... 42 cups. No wonder children died so quickly.
Our ancestors, drinking from polluted watering holes on their western treks, would contract cholera and within a day become dehydrated to the point of death. Awful, awful. And to our ken, so treatable...... if only they had known to avoid drinking this water but apparently they did not.
Aren't we lucky doggers and people these days?
