Quick update, the Siamese - Flame hid Foxie - Salt & Pepper Mask and the next one I popped was a Chartreuse hiding Toyger - Caramel, so popping box number 4 another Chartruese to see what he hides
the other 2 boxes made by this pair were Foxie S&Ps so I'm due both passing shown fur at the same time
6 boxes
2 Foxie S&P's
1 Siamese Flame hiding Foxie S&P
3 Chartreuse, 2 of which hide Toyger Caramel, so looks like the Flame is the difficult one.
These cats know how to frustrate!
