Welcome to the joy of colubrids in general, and bull snakes specifically. They're awesome snakes...more active (& diurnal), easy to feed, & if yours is a hatchling, just
be patient...some are much sassier (ie. defensive & nippy) than others, but mostly all calm down with respectful handling. They make great pets, IMO. I've bred & kept
them in the past....I don't currently have any though, so I shall enjoy hearing about yours.Bull snakes need spacious caging...I recommend keeping yours in a large glass tank with a very securely fastened screen top, since they are NOT shy about pushing hard (& some are prone to rostral scale damage, so watch for that, you might need to make modifications). They do best with good air-flow and much lower temperatures than your BPs. I recommend using UTH in one end of the tank for your bull snake's digestion, & unless your house is unusually hot or cold, the rest of the tank can be room temperature.
