Now, i have heard that a cat, raised in a room without corners can not see tree's. Not only that, but anything that is straight, is this true?

[another_someone]

Have not heard that, but the brain/eye does process straight lines separately from curved lines, so it is plausible that the part of the brain/eye that deals with straight lines might fail to develop if there is nothing to practice on (one question might be whether this is a permanent disability, or merely that the animal might have to start going through the learning curve late in life).

Yes i have heard that and saw something which delved slightly into it on the TV. . Supposidly an experiment was performed where they were raised in a room there was nothing vertically visible (circular room)and when they were exposed to an normal enviroment they were unable to percieve or maybe understand up or down.

How can you tell if a cat is blonde?
No matter what height you drop it from it always lands on its head!

[SquarishTriangle]

How many perfectly straight trees have you seen?

[Bored chemist]

All of them, but I was raised in a shperical room.

[SquarishTriangle]

Oh that explains a few things.

[Bored chemist]

With a name like that...
