If ontogeny recapitulates phylogeny, does it also mean that animals see world more like babies (and vice versa)?
Still an interesting question, though. I've seen cats focus pretty hard on certain things.
When your cat crouches down and does that ass wiggle, he's pretty much driven everything else from his mind except ballistic calculations: distance to target, plotted trajectory, azimuth, elevation, etc.
It pays off though because he either catches the mouse or, if he is more relaxed, does a perfect four-point landing in your lap with a minimum of impact.
