I do wonder if it only appears in the worldline that SO is in due to it knowing about what he is doing and knowing that he is being rather lenient in checking and keeping the world in line, and what they did can be seen as a disturbance in what the main cast is trying to do but it also helped in dragging the higher out of the way but is it just me or does the white cat seems kinda disappointed or annoyed? maybe like it predicted something like this will happen. Also wondering if SO knows about the white cat since he seems fond of it, though unlikely .....

No I think the whatever the white cat system is definitely is aware of SO but not vice versa, at least not for now. Remember, so originally wanted nothing to do with the white cat because “he doesn’t involve himself with the beings/cats in the settings” but thought the cat was cute. But I think it’s either part of the white cats camoflauge, prerogative, mission or something to be around them so hence here we are. But it keeps dragging the attention of the main creator system to our MC and ML being outliers as well.
The white cat that SO flirts with (green and yellow eyes) is the defector/traitor (whatever classification the rebel systems went by) that the creator world god became alerted to originally. I believe they briefly mentioned rebels or something of that nature. You see it pop up in multiple worlds because it’s part of the bugs and a grander scheme of what’s happening I’m sure, they showed his humanoid form in one of the chapters though.
