Q: Dear Nora,
My cats have a large water bowl that I always refill when it gets low. Still, I frequently find them sneaking water from the kitchen sink, my own water glass, etc. What gives?
A: There are two things that may be happening. First, the water may not be fresh enough. Our wildcat-ancestor survival instincts are still very much in tact, even though we let you think you’ve domesticated us. If your cats are thirsty and the water smells or tastes bacteria-laden, they may avoid it. Keep in mind that our senses are a lot stronger than yours, so something that seems fine to you may be disgusting to us. Try using smaller bowls, which will force you to refresh the water more often. Also, give the bowls a good washing at least once a week.
Secondly, in a multi-cat household, weaker cats may seek out alternative water sources if a bully-cat is watching over the bowl. To solve this problem, put water (and food) bowls in several locations throughout your home, so there is always a safe and accessible alternative.
