ClydeSight2.0!

Now, pay attention class!

This seminar module is all about Cat Vision, how we cats see what we see. You humans can't see as-- well-- you'll find out soon enough! Your FDA (Feline Digital Analyzer) is below and Eddie Cat will explain how to use it.

Use it wisely and well, and you'll do fine on my surprise quiz! (oh, now it won't be much of a surprise, will it?) Oh, well...

1. Click on a topic on the remote control

2. Click on the Analyzer Off button
to end analysis.

I wrote some tips for extra credit
below the analyzer!

Extra Credit Tips:

1. We cats can't see in total darkness. There must be some level of light available.

2. Scientists have determined that we cats do perceive color, but our behavior indicates that we don't have much of an appreciation for it. Well-- we don't want to make it too easy for the scientists!

3. Our cat eyes don't give off light (as in our beautiful glowing eyes.) Our Tapetum Lucidum reflects light, creating the glow effect.

4. We cats can see things you humans often miss, like a small insect flying through the room. This sometimes makes it appear that we are seeing "ghosts" or things that aren't there.

5. We cats have an internal eyelid that closes when we sleep. Please don't go looking for it-- we need our beauty sleep!

6. Our pupils (the opening in our eyes, not our students) automatically expand for light conditions, just as in you humans, but our pupils have a wider range of motion, going from the commonly seen "slit" to a wide open circle. The pupil dilation indicates our sensitivity to the ambient light, not our mood or emotions. We have other ways of expressing those!
