So I decided to check how the family tree changes depending on pelt.
Gray, dark tabby, ginger, and hairless- your entire family matches you
White and black- your siblings and mom's side match you, while dad's side are sandy
tortie- dad side ginger, mom side black, Rocky matches mom and Pebble matches you
dilute tortie- same as tortie but everyone is dilute (dad side sandy, mom side gray)
tortie w/white- dad side black, mom side + Rocky ginger w/white, Pebble matches you
dilute tortie w/white- dad side sandy, mom side + Rocky gray w/white, Pebble matches u
I don't know if this is of use to anyone but I thought it was mildly interesting, didn't check if gender effects it though
