Are cats atheists?

[Zen Badger]

Atheists are generally very clear that they want atheism to be defined as a lack of belief in God, and not the belief or claim that there is no God. If this is so, why aren't cats and trees and birds and mentally challenged people who cannot think about things like the supernatural realm atheists?--they all lack belief in God too.

Because they don't have to put up with christian idiots telling them they'll go to an imaginary hell for not believing in an imaginary sky bully.
