I feed my snakes in sterlite boxes. After each feeding I wash the box with soap and hot water, then use quat (a sterilizing agent), and let the box air out before I feed another snake in it. This makes for a lot of washing - especially on nights when I have more than a couple of snakes eating. My snakes are living in vivs next to one another and have been out of quarantine for several months. Is all the washing really necessary, or am I just wasting water?
