I would put the corn in a T8 in a heart beat, he is currently in a 3 foot cage and can't stretch out in it and is constantly on the move. Clibming and going back and forth from side to side. The same has been said for the childrens. Everyone I have talked to that owns one said a 3 ft cage is nice but they will use every inch of a 4 foot. A lot of people put their adult BPs in a T8 as long as you keep them comfortable with plenty of hides its a good enclousure. I like giving my snakes the options to move around and dont want to keep them cramped up. The only thing I would put a divider in the the the T8 for is KSB.
