Rare Cat Genetics: Complete, Sectoral, and Central Heterochromia with 'Blue-on-Blue' Eye/Fur Contiguity in a Dilute Calico-Torby Mosaic.

I’m fascinated by the science behind my cat's unique look and want to understand—in layman's terms—how it happens. I know it comes down to a split-second pause during embryonic development—like a 'door slamming shut' on specific migrating pigment cells while the rest of the cells keep moving. But just how rare is that timing anomaly? Now, stack that with her 'blue-on-blue' eye (a dominant blue eye with absolutely no white fur touching it), a trait mirroring the extinct Ojos Azules breed and recent DBE lineages like the Celestial, Altai, and Topaz. Plus, she’s primarily a dilute long-haired calico, tortie, and tabby mosaic, but with striking spots of non-dilute orange (a caliby-tortico). Does anyone else have a cat with these kinds of stacked rarities? I’d love to connect with their person and talk cat genetics!
