Also, to add on to my original reply, we had him for about 5 months and he was very alert and active, albeit a very weird acting snake. Another thing I just remembered, he never shed. Not once during this time. But I would think that having him for 5 months would allow for any illnesses to show. Also by weird acting, he loved to just sit on the glass halfway up (cool and warm side at random times), but he’d soak in his water, climb his tree, sunbathe on his hide, sleep in his hide or in the branch. Very alert when taken out of his enclosure as well.
