What would you call a wild trait? An instinct? Don't dogs and cats still react instinctively? They will snap or run away if scared just like a reptile. What happens when a litter of kittens is born in the wild? Do they not regain "wild traits"? If that is so how can you say that wild traits have been bred out of them? Certainly physical things have been adjusted and the ease with which they become socialized but an animal is still an unpredictable thing whether domestic or not and this unpredictability is often pinned solely and unfairly on reptiles. If you can see your reptiles pehaviours for what they are you will see that they usually are not all that different from othe rdomestic animals.
