I'm not sure if this has already been created or exists, if so I'm sorry. Would anyone be willing to retexture the cat to look like Luna from Sailor Moon? Gif below for reference.
The closest we have so far is the black cat mod by Ex0dus13. They might be willing to make a version of that one into Luna for you. There's no harm in asking
Here's my best attempt! I used a cat base from the Longhair Cat mod by @Korokos (with their permission). You can find the file for here on the Nexus. Just replace your cat.xnb file in the Animals folder with the new one from the download.
