In my full belief, when the word "love" was defined here it wasn't meant to be anything like human love towards another human. No I am not crazy enough to believe that my snakes loves me in the same way my fiance does. I don't believe any animal can have the complexity of love that humans carry. But I do believe they show their own form of love ie: "I recognize your scent and it is comforting to me because whenever you hold me I get warm and receive positive responses and praise, and you're warm, therefore I am going to show you affection back" or "I am really sick and every time you come near me I know that I get Qtipsshoved down my throat but its making me feel better so I am going to give you affection because you are warm and make me feel better."(And no I do not think a snake knows what a Qtip is for all the people that are overly litteral here.) But either way, don't assume when people say that word love it is they type of love that a human shares with a human, think more like a cat, it's the only animal I've been able to compare a snake to so far.
Also, we don't know what animals are truly thinking. Maybe our snakes "love us" maybe they just see us as a huge freaking goal to eat when they get bigger much like the "adult" plate when you're a kid. All I know is something makes me snake show some forms of affection with me, and if all the science buffs on here want to truly believe that their snake is a mindless killing machine that only doesn't eat them because it doesn't think it can then you can have that. But I am a believer, I am a dreamer, and I think my snake loves me!!!!
