You are being followed. 

Nothing coherent tells you this. You are in NeoSydney, the economic capital of PanOceania, a place both intensely populated and working incredibly hard to make it seem like it wasn't. Huge boulevards and parks, massive open spaces filled with natural light, groves of native banksia to break up sight lines - the atmosphere was designed to make it feel like you weren't in a city at all. Everywhere you're surrounded by old brick and carved sandstone buildings - but glance up and the dizzying skyscrapers arise in all directions. The skyscrapers wear the hollowed-out facades of the old buildings for the first few stories, and then erupt up into the sky once they're out of the field of view. The only reason it feels dissonant at all is because you're just back from the real country. That - and you're being followed.

This is a cat instinct. Advanced side effect, prey instinct - but not a dread. You're not being threatened with death. But - there is another cat. Another cat at a higher altitude than you. Looking down on you. An uncomfortable sensation, a constant reminder that you are not the most cat that you could be. It's been following you for a while. How do you cope?
