That is a very large enclosure for a ball python. What are your temps? Ball pythons really don't need that amount of height or floor space. I would suggest moving it to something alot smaller....like 36" x 17" x 6"
All that extra space, just makes it more difficult to heat and just isn't utilized by a bp. I understand you want your snake to have lots of room, but they're not like a dog that enjoys it. These are animals that like cramped spaces, and probably only venture out for short periods. Providing optimal conditions ensure that your animal will stay healthy for the duration of it's life.
Cause when push comes to shove you taste what you're made of
You might bend, till you break cause its all you can take
On your knees you look up decide you've had enough
You get mad you get strong wipe your hands shake it off
Then you Stand
