Dominant to Tiger! - Shadow
Putnam hides Tiger! - Shadow, has to come from him as Jolly hides Toyger - Snow or more recessive so can't hide the Shadow (Celestial did hide Toyger - Snow)
Putnam and Jolly had a British Shorthair - Chocolate and White so it must hide Tiger! - Chartreuse or Tiger! - Shadow making it dominant to Tiger! - Shadow.
