In fact, my first reaction wasn't to jump back inside my door and watch from a safe distance - I ran and got my phone to snap the pictures. While taking pictures, I was patting my leg and making alluring kissy noises to entice the little "foxy foxy" to come closer.
Foxy trotted off, but I'm sure I'll see her again. When I got back up to my apartment, I googled "are foxes dangerous?" Turns out they are just rabid. Some people hand feed them. Of course I'm going to try.
Unfortunately my fearlessness caught up with me later in the day. I was ferociously mauled by a six month old domestic short-hair.
