This is my first whole summer with my ball python, and as long as I've had him, he's spent most of his daylight hours in his favorite hide. But the last week or so as we've rolled into summer, he's out in the open more, particularly on the hot side, basking under the lamp-- not really actively moving around, just staying put. Surface (88 - 90) and ambient (80-82) temps haven't changed in several weeks. Humidity is consistently regulated between 50% and 60%. Nothing in the enclosure has changed. He's eating regularly (every other week, medium rat). I've read where cleanliness can affect pythons' activity, but I keep his cage clean. Is this normal behavior?
