I looked at the comments at all three places and found that the comments were restricted to two major themes:
What a great kid Wendell is and how we should all raise our kids like him.
What terrible little shits the cat-torturers were, complete with condemnation of a society that lets this behavior flourish.
Missing from the discussion: Wondering if the cat was asking for it by being so cute and easy to torture.
