Obviously reptiles are not mammals and should not be given emotion as such but there is research that shows a reptiles brain is not as simple as we once thought. I had read an article a while back that shows a study on reptilian brains and how they are not so different from our own.

The study was done on lizards, not snakes, and what a reptile's brain is actually capable of is still TBD. I think the bottom line is we have no idea what they actually experience so it is important to treat all animals with respect and dignity. Do I think your snake experience "love" as you imagine? Absolutely not. Their brains are different and work in a different way than ours. I do think it is important to keep this in mind because, as was mentioned earlier, signs of stress can be missed. Your snakes "missions" could easily be a stressed out animal. Just food for thought.
