I find it interesting how their pupils dilate right before they are about to pounce.  I'm just guessing, but perhaps they want as much light as possible to see movement of critters while sacrificing detail due to things being overexposed.  Let's see if google has an answer for me...

EDIT:  I was close.  I couldn't directly find an answer to my specific question in my short search, but I pieced together one that makes sense, borrowing some of my knowledge of film cameras.  When about to pounce, a cat needs to judge distance.  There are three ways to do that: 1) moving your head and comparing two images in your recent memory; 2) stereopsis, which uses the difference between our two eyes (and what 3D glasses use to trick our brains); and 3) blur, or depth-of-field as it's known in the camera world.

Depth-of-field relates to how much is in focus in front of and behind the focal point of a camera lens.  If the aperture is really small then pretty much everything in front of and behind target is going to be in focus. If the aperture is wide open then only the target will be in focus.  So by opening their pupils as wide as they can it is much easier for the cat to tell how far away their eyes are focusing, because only the target will be sharp.

This became adorable enough to share because of the poems added by tumblr users:

Just realized that I didn't thank you for this, VoC.  What you found out and then extrapolated from makes perfect sense.  Thanks!

No problem!  Another interesting thing I found out: before jumping up on a ledge a cat will bob their head up and down. This is also to help judge distance using parallax. Basically doing this:

Pangolin baby riding mama's tail.  Pangolins are one of the most endangered species on the planet, poached for their scales. :'(
