Hi there. If Star is acting normal otherwise, I wouldn't be concerned - there aren't really any illnesses that cause decreased water intake as an isolated symptom, so it's likely that he just isn't very thirsty right now. The weather may have been cooler today than it has been, or he may not have exercised as much for some reason.
