Thank you for the link regarding feeding in the snake's habitat. Indeed, Hatfield and McCoy arguments. I'll stick with feeding him where he lives . . . if he ever decides to eat.

Incidentally, after the hissing bout we let him rest for about an hour then I took him out of his enclosure and handed him off to my hubby. Haku curled up inside hubby's hoodie at the waist and stayed there for an hour, just as happy (and warm) as could be. No sign of aggression or fear. We decided to put him back in his home when he decided that he wanted to investigate the back cushions of the sofa. The last thing I need is for the snake to go up into the sofa's inner structure.
