Additional eye shapes and/or pupil sizes?

[Vrem Vaniva]

I'd kinda like to see "huge" pupils, since RL kitties often appear that way when they are sneaking, sleepy, or otherwise just looking their most mysterious.
(Huge pupils might be good for blacking out unwanted eye colors -- but then why breed with unwanted eye colors in the first place? There are only a few eye colors i'd want to do this to.)

I'm with Tad on this, though --
The number of "permutations and combinations" is already mind-boggling, so having only 2 possible eye shapes, and 2 possible pupil sizes, helps to keep a lid on it.

It's also one pair of traits that you can get without being an expert, so it is nice to have this small area where you have a 50% chance of "a success experience."
