this is completely off topic but was just reading on cat genetics.. and thought of your babies..

Angel´s dad.. surely was an orangie and probably the dad of the new "batch" too..

male cats need one orange gene to be orange
female cats need two orange genes to be orange, if they only get one then they are torties..

Winnie + orange dad = tortie female Angel

tortie Lilac + orange dad = tortie female Carmela, blackie boys Chuck and Chip, orange maleSunny, and you could possibly get orangie girl Tangy too.. as she could have got orange from mom AND dad...

then the newest crew
tortie momma + ?= orange male, black? and siamese?

lol.. just wanted to share as I found it interesting
