Fascinating!
I think I meant bonding more in the mammalian sense, but we are talking of reptiles so maybe that's asking too much. I think my snake knows that I will not cause them harm, but beyond that I don't see much bonding. I think putting it terms of 'safe' and 'not safe' is a good way to describe it. I don't believe they are capable of complex emotional bonding or love. But that's ok. I just enjoy them for what they are IMO.
