"cats have a visual field that spans a whopping 200 degrees, as compared to 180
degrees in humans"

I disagree with this. Firstly, I tested my own vision and I have 220 degrees.

Yeah, mine is much wider than most peoples' too.

You mean my 220 degrees is odd?

Just that its unusual for humans.


Meanwhile, back in the real world...

"The visual field of the human eye spans approximately 120 degrees of arc.
However, most of that arc is peripheral vision. "
