I built Cat Mob Statues of all 12 variants in the game at a 1 pixel : 2 block scale.
Schematics for all statues and a map with all of them are included in the download.
I tried to get the colors as close to the ingame textures as possible, but for some cats it just didn't look right. So for the ozelot and the red cat I chose a much more saturated color palette which resulted in a very comic-y look. Please let me know, if you have an idea how to get the colors for those statues closer to the ingame mob!
I tried to texturize the "all black" cat by using black concrete and wool, but you could also use only black concrete and it will look good (or even better to some).
Fun fact: The Persian cat has a squished nose and I never noticed it before.
Feel free to download and use the statues however you like, but please give credit if you do :)
