i don't personally own any, but pat is right... the majority of the scrubs you see are morelia amnthestina. they are big and can be untrustworthy.
a friend of mine has a couple dozen of them and let's just say he has a giant plexiglass shield that he uses when he feeds them. their feeding response is off the charts... they're also very smart for pythons.

a lot of people that own scrubs end up getting tagged in the back of the head or have some other weird story for ya. hopefully some will chime in... definitely a snake for the advanced hobbiest.
