Although it is raining, the cats are not crying. The sentence just reads well. But it does bring up a question that has always bothered me.We all know that humans have a irises which are round. Optically that assures that we see everything is magnified equally in all around us. Other animals have different shape irises. As an aside, chameleons even have two eyes that move independently, that should confuse anyone (or anything). But chameleons seem to adjust to whatever their brains interpret.
But cats eyes and most reptile have irises that are vertically long and narrow under high light conditions changing to round irises under low light conditions. The directional magnification of what they see changes from high to low light conditions. I'm sure there is an evolutionary reason for this but it escapes me at the moment. Think for a moment about the optics of a vertical iris. Objects would be magnified in the horizontal plane but be unchanged in the vertical plane.
Confusion over the optics of a cats eye is proof that we're all on this flight together.
