Love me some piebald, which I forgot to mention in the video is the non-cat-specific term for bicolor lol. Also, much like "niche," very single professor I had in college pronounced "leucism" & "leucistic" differently, and I'm already bad at pronouncing things, so go easy on me.

The deuteragonist in the book I'm writing is albino, and so are a few others, and this was really helpful! None of the characters in the story are completely white, and to be honest, do not follow genetics very well. They all have at least some faint patterning, one of them does only for artistic purposes, one of them does because I didn't know how it worked before and I don't wanna change her appearance that drastically, and the other two don't have to be complete albinos for the story-- You've taught me that deafness isn't tied to the albinism :D So one of them doesn't have to be albino and the other I only called albino because albinism is recessive so both parents need albinism, even if they don't show it, but she can be Aa (I use AA, Aa, and aa for albinism) 5:39 meow

my cat is a black tabby with white socks on his hind legs. a part of his "original" coloring hits a part of his beans, making them half black half pink! it's so interesting to see! his forepaws have black beans because there's no white there

I’m on vacation in an apartment in the Canary Islands. I’ve noticed a lot of cats around but they all seem to have one thing in common, they have short tails. So I have a question, is tail length and other stuff like ear size and height gradient traits or something else??

@littlehungrywarrior 8 ай бұрын

Fun observation! In general, bodily proportions are gradient traits. However, while tail length can be affected to a degree by polygenes, if you see a cat with a Stubby Tail (as opposed to just A Little Bit Shorter Than This Other Cat's), there's 2 specific genes that could be responsible: Manx or Japanese Bobtail. I'll cover both of these in a future video ;)

@prcervi 8 ай бұрын

do you think white spotting could make a color point looking cat? i ask because i have a seal color point cat character with yellow eyes and i want to try to make her genetically work without either pulling out the "it's a mutation" shield or just chucking realistic cat genetics out the window I'm already planning to throw out part of warrior cats setting by making the cats more like the felynx/melynx of monster hunter or the ghibli film The Cat Returns

@littlehungrywarrior 8 ай бұрын

I suggest watching my Albino & Colorpoints video! I can't say it's /impossible/ to get point-esque pattern from white but it's exceedingly unlikely, I've never seen or heard of that happening. If you want a seal point with yellow eyes, I recommend just going with a very hot Burmese lol. You don't need to worry about the "it's a sudden mutation" problem bc it's recessive to fullcolor anyway; it'd be MUCH less likely for some kind of bizarre, unknown white spotting pattern to perfectly mimic point than it would be to just have Burmese skip a few generations tbh. The former sounds a LOT more like "sudden mutation" than the latter.

I have a quick, somewhat related, question. Is there any research on how spotted leathers happen? Is it only in cats that are two different colors, like bicolor cats and/or tortoiseshells? Or could a whiteless tabby or solid cat (and maybe a full white cat) have spotted leathers too?

@littlehungrywarrior Ай бұрын

Spotted leathers are the same mechanisms as spotted fur. So if the area's depigmented, that applies to skin and fur. If the area's eu/pheomelanin, that applies to skin and fur

Is the blue eye thing also a lack of pigment in human eyes or is it just a cat thing?

Yep! In every mammal that I'm aware of, blue is underlying structural color beneath non-blue pigmentation. I don't think that there's such a thing as blue pigment

I'm not Deaf so I can't speak definitely and you should ask someone who is Deaf about it, but from what I've read from Deaf warriors fans, having the ONLY deaf character in your entire book series exist JUST to be killed off in a way that happens specifically bc he can't hear as a cheap plot device to get a queen to move to the elder's den is...pretty offensive!
