I am a day behind due to a day out with the family yesterday.
First, here is Mary's article on the subject. I definitely saw some things that I don't have in my kit and will take steps to add in the future.
It also included pet kennels. Having been in a F5 tornado (fortunately, it skipped over our house and touched down before and after) I can tell you that pets are really affected by the pressure change.
They whine, turn in circles and are very uncomfortable to the point that it is possible that their humans could be bit, scratched or both. Cats are especially liable to scratch and try to run off. To keep them safe, I had a kennel for each in the shelter.
