Also: when you keep 2 snakes together, they are competing for the optimal conditions in the cage, but it won't be obvious to you...it will likely cause them stress
though, & that can result in one or both getting sick. Maybe not right away, but a little ways down the road...and then you have 2 snakes to treat, not just one, so
it gets more expensive & less likely to have a good outcome. I can't recommend housing them together...no matter how passive they seem about it. And after you
feed them, they may still smell food on the other snake, & uh, "accidents happen" too...they could kill each other.
Also, many snakes are mis-sexed, so you could have reproductive surprises to contend with as well...and while you may think "oh boy! what fun!" it can also go the
other way & require expensive veterinary care. Breeding snakes (or any pets) un-intentionally is not a good idea at all.
