Cheetah! - Ginger Flame is recessive to Bengal - Copper.
Jay must have passed his hidden Cheetah! - Ginger Flame fur as his 'visible' (abeit under his costume) fur is Pandie - Ebony & Ivory and we already know that is dominant to Bengal - Copper; if he had passed the Pandie E&I fur we would have a Pandie E&I kitten.
