Interesting! This might explain why our neighbor's cat specifically comes to our garden once or twice a day to drink from our muddy pond, even though it has a water bowl at home. When I had my own cat I also observed that he would prefer to drink from muddy puddles outside than from his water bowl indoors, I thought he just didn't like the chlorine taste of tap water, but perhaps he also wanted some minerals!
