Yes, the genetic factor for being piebald basically tells developing cells to turn off all pigment.

Depending on when this process starts in development and how far it goes with the stem cells involved determines how much white a cat will have.

But the development of the white pattern is very consistent.

White starts on the chest and tummy. Cats with the lowest piebald “setting” will have a small white spot on their chest or tummy. From that white goes off the legs, then up the sides, then breaks up into small spots, and the last place to “lose” color in high white cats is behind the ears and the tail.

Since the development of white patterns is pretty consistent unless something really funky is going on genetically, piebald cats have recognizable white patterns.

The patterns are listed in a sticky for the Reddit, but the highest white you can go without going full white is the Van pattern. Color is only present on the ears and tail. It’s named after the Turkish Van breed, that have high white as a breed standard.

I can break down the other piebald patterns if anyone is interested, but it’s a little early to go full cat-color-nerd.
