Like i tell everyone, Corns are subspecies of Rat snakes, and Rats are the nippiest snakes around, they have bad attitudes as babies. But of course as GoFride said, with proper handling and care it WILL calm down as it gets older and gets used to you. In the mean time enjoy the cute little threat poses they give you and the painless bites. Corns and Rats are truely awarding to work with.
Good Luck!
