Welcome to the world of ball pythons. They like to sleep....a LOT. There will be periods of activity...most typically when they are really hungry or when something has been changed in their enclosure and they have to check it out. And then there will be long periods where its seems like you have nothing but an empty cage to look at. Most of the time, they'll just chill in their caves....day or night. They really don't pay all that much attention to clocks or our predictions.
