On The First Day of Nerd Book Giving...

My (most excellent) Comic Book Friends suggested to me:

A Zany Book with a Zombie Kitty

Zombie Cat: The Tale of a Decomposing Kitty is the story ofTiddles, a suave, carefree kitty cat whose only pleasures in life are eating mice, wooing the ladies, and being generally apathetic toward his owner, Jake. But when a toxic spill occurs outside of town, Tiddles finds himself savagely attacked by a nasty-looking radioactive field mouse, and he wakes up as one of the undead.

It's generally gross is a highly humorous way.  A perfect gift for your zombie loving daughter or son.  If anything, it will creep out the relatives, which makes it even more enticing...
