I thought this issue was great, and just a little bit better than last weeks Jurgen's Action Comics issue. As an animal lover the cat thing really shocked me in a way that I don't think a human being being maimed or injured would have.
Unfortunately I'm used to seeing people injured and killed in entertainment, and this really drove home the point that Jon is like a loaded weapon when his powers aren't kept in check. Prime Earth is lucky Clark and Lois are raising him!
