My wife and I just purchased a ball python a week ago. It's about 18inches long. It's been extremely timid it even struck at my wife at Peta mart. My wife was reassured by the store clerk that that was normal stress so she took him home. I made sure the snake had the proper lighting and a dark shelter for him to hid in. Recently though if he's out and you are anywhere near his enclosure he strikes at the glass. I am getting worried for his safety not sure if I should take him back and try somewhere new.
