Are cats atheists?

[Mystic]

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.

The way I understand disbelief, is that it means you chose not to believe in something when presented with the idea.

For example, in Islam, disbelieving in Islam only counts, if you believe not in Islam when presented it.

So if an animal was presented the idea of God and then didn't believe in it, then it would be Atheist.
