My cats exhibit "drug seeking" behavior all hours of the day that their food bowl isn't filled (I don't give in), if this is the criteria. I think the study would be a little less useless if they would have not taken the food away. If the fish are choosing drugs over food, that's a bit more indicative. Although, we really need to see if we can push these fish to the point of robbing old ladies on the street for that one sweet hit of hydrocodone.
