As I said, that is certainly MY opinion on the topic. I have read many posts regarding snakes with the trait and never had any reason to think that the animals were inferior in any real way. My snake, as I said, is great.
Sorry, no pics. I am still in the stone age w/no digital camera.
As far as your parents are concerned: I always say that education is the answer. I will tell you that I have kept many animals as pets in my 46 years, and snakes (especially North American Ratsnakes) are among the easiest to care for. A toy poodle can and will give you a worse bite. A playful kitten is probably more likely to draw blood. They don't stink. Feeding frozen/thawed rodents once a week is an easy and clean routine. You may need to keep a small supply in your freezer, but as long as the plastic bag is inside a paper bag nobody has to look at them.
If your breeder assures you that he will not give you a bug-eyed animal, you can probably count on it. If you had a chance to go to some shows where you might find some, however, you could decide for yourself if you would be willing to own one if the price was right. With Texas Ratsnakes, especially since your folks are still deciding, I would try to find out if there is a reptile show near you. If you can find a selection, you could handle a few animals and choose one that seems calm already. As stated previously, however, mine started out nippy and feisty but quickly calmed down. For a first snake, though, you may want one that doesn't even start out nippy. Good luck. Duffy
