I have been the proud owner of two of these beautiful snakes and can say with my hand on my heart that they are the height of friendliness and are no trouble at all. Our three cats go to their viv and plague them through the glass and are still in one piece and my kids love them to bits. But that doesnt mean that i trust them 100 percent , i keep the viv locked at all times and am always present in the room if they are allowed to wander. They wont become friends with you even after years, their only thoughts are for themselves and their bellies. But i dont mean that they will attack if given the chance, snakes are basically lazy and if you look too big to eat then they would rather not bother
