The two main "emotions" I think most if not all animals can feel is stress and contentment. I believe reptiles also possess fear and familiarity, and some more may experience a food-associated or pseudo-companionship type of relationship. Many definitely enjoy the warmth from people too. I have owned frogs which, at the very least, can understand the behaviors and actions I took before I fed them and of course turtles often splash around and reach for their owners in their tanks if they think they are being fed. Its very cute![]()
