I am in the process of raising my baby veiled. They are a great beginner chameleon, but chameleons are far from great pets in a sense they like to be alone. It involves excessive care and hard work. I would shy away from a veiled chameleon because they should not be handled and tend to stress out over tiny things. If your nephew plans on keeping it as a pet there should be very little handling. Its a huge responsibility.
I agree completely
