Yeah, Steven! WOW! Fascinating. I like the first paragraph as it explains "Why?" to me. So, like if we could live a million years and watch the cat-eyed snakes like up in MN, MAYBE evolution would change their eyes to round. Do alligators have cat-eyes? I'll have to check since they're found in warm zones.

Are there any warm-zoned snakes that *don't* have cat eyes? If so would they then be active during the heat of the day? But red bellies are active at nite (I think I read that here; I'm positive I did) and they have round pupils.

It's all very confusing to me. But fun and interesting and I'm sure I'll get it once I get education on boas, pythons, genus, species, locales, etc. It's just a matter of learning. Keep the info coming! This eye-thing is ssssoooo fun to learn about.
