As any cat owner would know, cats sometimes have a tendency to be a little...rude. Sometimes outright mean, depending on the cat. Not only that, but they really don't care about their behavior either.
They're chaotic and they know it, they just don't seek to change it because they know we love them anyway. This is evident in the photos on this list of 20 times cats proved they're assholes and don't care about photo evidence.
