My Dad doesn't like snakes, but I love them, I need some ideas to help convince him to let me get one.I would be getting a Ball Python or a Brazilian Rainbow Boa. I already have a cage with a locking screen top, from my old Bearded Dragon who died, it is 40 gallons. I have already done my research, also if you could suggest any other breeds of snakes that would be great (I do not want a colubrid). Thanks.
