And another, can 2 snakes easiliy be housed together? There are 3 or more in the pet store but those are young and I don't know enough about them as to how they share space as they grow.
Because a pet store does it, does not mean it should be done, most pet stores try to display as many animals as possible for the least money possible explaining why they house them together.

There is no benefit in housing snakes together, however many issues can arise that have been documented such as stress, going off feed, spreading of diseases and/or parasites, premature breeding, injuries, and even cannibalism
