Couldn't have put it better myself TOLB.
I also believe that if the person handling the snake is calm, the snake is more likely to be calm, which could point towards some recognition of "feelings", although nothing as complex as love. I've handled snakes at my work that the other guys call me crazy for, when I had no idea it was even a nippy snake to begin with. Because I was calm and confident in handling the snake, it was alright being handled. That's what I've gathered from my experience. So fear/comfort/contentment yes, love no.
