sorry to tell you this, but your cat only knows one thing about you - which is that you are part of a non-superior species, basically - not good for nothing. If you tell your cat "i am such a failure" your cat will think something among the lines of "yeah right, and you only finding this out now?..." Cats do not think much about humans. It is better to talk to a different animal, such as an elephant, who is way more compassionate and sensitive
