At 7 years old, Anna-Kat is the youngest member of the Otto clan: tiny, adorable, and sweet. She has OCD, which results in some strange behavior: she has to stand still whenever the clock is 13 minutes past the hour, she has one ritual for going up stairs and another for everything else in her life, and she is compelled to pee exclusively in the back yard. At the same time, she's a total germaphobe--even though she's learning the hard way where she can and cannot put Purell Hand Sanitizer. Despite her father Greg trying to teach her that "friends are more important than germs," Anna-Kat has a tough time making friends in Westport. But her mom Katie takes solace in the fact that Anna-Kat's getting the special needs attention here that she requires, and Katie hasn't found like a bag of cat heads in her room yet or anything like that, thank God!
