I feed on Wednesdays. If I have herp-related events to go to, it's usually on the weekends, so I don't want the snakes having a full belly when I shuffle them around to go places like that. Also, as mentioned, the time I handle mine the most are on the weekends, so it makes more sense for me. Also, I do most of my weighing on the weekends as well, so I want to weigh them empty.
