Such a cutie! And her coloring is really beautiful. Yes, that pattern that looks like camo seems to be the tabby pattern called broken mackerel (stripes with interruptions). When tabby markings are on a kitty with a solid color coat, they're called ghost tabby markings.
I just looked up blue (technically, that's what gray kitties are called) with ghost tabby markings and read that most often, those markings will fade once they're adults, so take lots of pics now!
Is she showing you who's boss yet?
