How to Spot a Psychopath

Our youngest cat, Millie, in near-infrared.

This shot was taken at night (f1.8, ISO 800, four seconds), by the light of two 500 watt halogen floodlights that I couldn't quite angle down enough to light Millie up really well. They still threw enough heat on her that she was squirming cheerfully around on the chair, though, which made it hard to get a shot of her that didn't look like a many-legged blob.

Here she is in visible light. She serves as a useful metaphor for the wave-particle duality of light, actually, since she is simultaneously spotty and stripy.

She gets on well with Joey.
