I think the classification of "Exotic" applies to snakes. When you own an exotic you become tuned to their natural behaviors and respond to them, if you are smart about it. You learn their body language and preferences and tailor your reactions and care to that. In doing so, they react in a "tame" way as long as you respect them for who they are and what they want and don't want. They can 'bond' to you in a similar way than any exotic can. You provide food when they're hungry and don't bother them when you shouldn't. They will learn to trust you and recognise you. I was very interested in exotic cats for awhile and learned a lot from that. Even tigers can form a strong bond with their owners and be very tame with them. But you can never lose respect for what they are and must be fully in tune with them. Are they domestic? No way in hell. Can you have a wonderful relationship with one? If you are always aware and approach with respect, absolutely.
