In my headcanon, there’s two types of albinos
Half albino fluffies are fluffies that has a white fur-coat but their mane being non-albino
Fully albino fluffies are fully white
This is probably the most shittiest info on this but I have nothing else to say 
Uh, actually, albinism is a total lack of pigment, so neither of these are albino fluffies because their eyes are not red.
They should instead be called Leucism fluffies.
Lack of pigmentation still allows for variety in eye colour. The rare brown ones, even.
The important factors are, from a Mythos perspective, cannibalism, a subterranean lifestyle, inbreeding, & mutagens, such as fluctuating electromagnetic fields.
Sometimes fluffy, or furry, small omnivores can help.
Correct. These fluffies are piebald and fully leucistic, respectively.
Albinos can’t have brown eyes, but leucistics most certainly can. Many real leucistic animals have normal-colored eyes.
Albinos can have lots of eye colours.
Unless they have degenerated away completely, due to subterranean horrors.
I’d argue half of those are currently mislabeled as albinism.
There’s even one (OCA3) that sounds much more like erythrism than albinsm. Erythrism causes red pigment where there’d normally be dark pigment.
I’ve always found it strange that there are seemingly no leucistic humans, but seeing these descriptions, I think leucism (as well as xanthism) may just be mislabeled in humans for whatever reason.
The Siamese Cat’s colorpoint being listed there is also surprising. True albino cats do exist and do have reddish/pinkish eyes, and white tigers are leucistic but share a similar mutation to colorpoint.
I wonder why it was decided to categorize them under albinism rather than leucism.
