Donut, who had been sleeping right next to me on the bed, decided at that very moment that she wanted to—for the first time in her feline life—go outside and explore. She jumped up on my shoulder, and she leaped out the second-story window onto the tree outside my apartment. Just like that. I’d had that window open dozens of times over the past year, and she’d never even given the window a second glance. But tonight, on the coldest night of the year, the furry asshole decided to Lewis and Clark her way out of the apartment.
