Curiousity may or may not have killed the cat?

This poem about Curiosity was among one of my favorites that I have read this quarter, mostly because it came up with a metaphorical way to present an idea that having curiosity is a GOOD thing, not a bad one. In the third stanza the first line, "Curiosity will not cause us to die- only lack of it will." The poem is saying that granted those cats may have used up all 9 lives according to this need for curiosity, they lived life to the wonders that it possesses. The two groups of people that roam the earth are either the "dogs" or "cats", the dogs refuse to fall subject to curiosity and when they do that they fall to a fainted color of what the world holds true and dear. With curious minds we have been able to do wonderful things such as; land on the moon, create technology so small that the naked eye can't see it, change history by simply refusing to move to the back of the bus, and slowly change the outcome of poverty stricken people across the globe. Without curiosity we would all be old dogs just waiting for our lives to begin,  and personally ? I would rather live life curiously...
