Three silver tabbies at the top of the fire escape next door; one skinny one wearing a collar and shivering slightly in the cool damp, one looking fluffy and muscular, and one with large black markings dominating its coat but still looking generally tabby-ish. When not watching me and my camera, the two without collars stare at the first cat. The one with lots of black bares its teeth at me. Two males courting a female? A near-frozen tableau for now, they've been in nearly the same positions for ten minutes or so.
