Describe the bug
I was messing around with the summoning and whenever I would summon a cat with the supposed white markings, but then they suddenly change to having a completely different pattern of the white markings.

To Reproduce
Summon a cat of any kind with the Ws-Ws gene

Expected behavior
A cat will spawn with one form of white markings, and a little bit later will turn into a completely different form of white markings

Versions (please complete the following information):

• Minecraft [1.16.5]
• Simply Cats [0.2.2]

So, the summon command is not great for white markings and I honestly probably won't dig much deeper to try to remedy it. (The summon command has been a huge pain in the butt... lol.)

If you summon a cat, try picking them up with a pet carrier and placing them back down to get their white markings working properly. Sorry for the inconvenience!
