Dhole markings (even if they aren't cats), sand cat markings, fishing cat markings, margay cat, and all kinds of cat specie markings as a few ideas, unless other markings around here are enough. Just some suggestions~ And maybe another suggestion could be a crescent moon around your shoulder blades, and also a star on your back covering your shoulder blades.
Those are all my suggestions so far, haha. So many ideas... o.o never said you have to do them at all. I could try and make a reference for both of the last suggestions too if you need them. Hurr..
