In response to a pretty insightful comment, I've decided to delete this one. It was an attempted followup to the Bratz post, to which I am not changing a word. I'm not exactly sure what I was trying to say, but it did come across as waffling, and even worse, incoherent. There's a reason I periodically go a few days without substantive posting, and posts like this one are the reason. They usually don't leave "draft" status. This one did, unfortunately.
If you really want to see the original, I have it saved and can send it to you.
Clumping litter is more effective, though.
