they are relly easy to keep. i think they are maby the same level as balls. they also seem to be much more active. balls liketo just sit in there hides all day but boas seem to wander around. the only problem is they take up a bit more space.
They do seem a little more intelligent for lack of better word than balls. The one thing is the size though, maybe a hog or saboga boa would be better. I have a rainbow and he is awesome.
