I know a guy who's the same way, and his BP is 16 years old. Or, he's had her for 16 years, I don't think she was a hatchling when he got her. And, well, it's worked for them for 16 years, I guess I can't complain. It's not the right setup and probably most BPs wouldn't have survived under such conditions. But if that particular snake is that old and is eating and otherwise doing well, I guess it doesn't bother him.
