Here I will follow two simple rules
1. Males will look like their mother's
2. Females can look like either parent or a mix of both (tortoiseshell/calico)

Ok so basically it's like a genetically accurate family tree (well kinda I bended the rules kinda but it's not too bad)

Also their heads are funny shapes

I changed Petalkit into a torti because I can, also I didn't change Patchkit bc he's so baby

Had to also made Reedshine a torti too soon that Willownose's and Shellheart's fur color makes sense

Ok so I changed multiple things here

1. Applefrost is now a trans ftm bc I say so (and because I accidentally thought he was a she-cat) and now has heterochromia
2. Shyheart now looks like Reedshine bc rule #1 (and no more Appledusk clones!) but I made him a color point to match his father
3. I made Willownose a torti also so Crookedstar and Oakheart's fur color can ACTUALLY MAKE SENSE

I would continue but I don't want too so I might add Crookedstar's family tree later
