I’ve released the Cat Analysis page for use. While there are a few pages on the menu, you need to just move through the top menu page. The links on that page will take you to the others as you go along, and back to the main page.
You should work your way down the Analyze page seeing if the modifiers apply to your cat, which hopefully will make figuring out the final color choices simpler.
Any problems or questions or bugs or thoughts on improvements in the page can be put in the comments here – if they are bug reports I’ll delete them once fixed up.
