I too have made Kitty Litter Cake for a party. It was a meeting of the LA Cacophony Society and it was a HUGE hit!

I know I made it once for an "adult gathering" when I lived up north and once at work. My co-workers actually requested it again this year, although I was too busy to make it.

In an unrelated tangent - the phrase "tasty baby cakes" has crept into the teaching plan for my heresy class. I think of that every time I see this thread.
