You really gotta gauge the personalities for this one.

Someone bought a kitty litter cake to my work for a cat lover about 5 years ago and that was the first time I saw one. I thought it was hilarious! I couldn't stop laughing at first. But...you know...not everyone saw the humor. And some were so grossed out that they would not walk by her desk. They were litterally disgusted (pun intended ).

But if they're all cat lovers..GO FOR IT and ignore the party POOPERS! (pun intended )
