To me, now that say it, your Longtail design looks something like this:

A black mackerel tabby w/ low contrast stripes.

And sleekclaw is also a black mackerel tabby, but a bit darker and higher contrast, like this:

Brindlefrost would be something like this, a blue mackerel tabby with a very white chest.

And I love charcoal, so if you're fine giving someone bengal ancestry somewhere up the line, you could say leopardface is a charcoal, like so:

However, since neither parent exhibits the inhibitor trait, which turns a brown tabby cat to "silver," what you've drawn Swiftfoot as, he doesn't really work.

(this is what you're picturing him as, right?)

So here I would either give him burmese color restriction, so he can keep the dark face stripes and his eye color, or give one of his parents the inhibitor trait, preferably Longtail cuz I don't think it messes with his design all that much, he'd just look like this:

and that would solve that whole issue, and give you an alternate path for Leopardface, that doesn't use rare, breed exclusive genes, which is making her smoke, like this:

These are just two of many different ways that you could interpret this family tree. For writing out a genotype, this is probably how I would do it, but I like rare exotic genes ahaha:

Sleekclaw: A/Apb, B/B, C/cb, D/d, Mc/mc

Longtail: A/a, B/B, C/cb, D/d, Mc/mc

Brindlefrost: A/-, B/B, C/-, d/d, Mc/-

Leopardface: a/Apb, B/B, C/-, D/-, mc/mc
