Most, if not all, of my cats have prefered their water separate from their food. Other than that, the cats have all had their preferences. The faucet drinker, the slapper, the one who needed complete privacy, the one who wouldn't drink unless the water was very fresh. Koa won't drink unless it is a bucket-full. I'm not sure if it is because of the height, the width, or that the water has been sitting and any chlorine has evaporated.
