I just exchanged e-mails with Ken Foose regarding a large male pseustes he has for sale.
The snake has been described as "Aggressive". I would classify some of my snakes as conforming to the several types of aggression as aggregated in the accepted and defined categories of animal aggression.
So you keep ball pythons and carpets............... do not take this the wrong way, but I would not expect you to be able to address a question regarding snake aggression.
