I have an adult male and he has been the sweetest snake his entire life. Really docile, never tried to bite or even hiss. I just came back from studying abroad for four months and my brother probably wasn't the most diligent about his feeding schedule. I fed him three days ago and he was being really moody and aggressive after the feeding. Even today I tried to refill his water dish and he practically lunged out of his cold side hide to strike at my hand. Is he just really hungry or could this be some sort of changing of the seasons horniness or bad attitude? Do your snakes go through periods of weird pissy behavior?
