NOTE: reference the Setup section for generating the Animals context and adding the Cats to the database used in this example.
NOTE: while you can click the "Delete" link here and the cat will disappear, deleting cats is disabled for this preview and the cat will return on the next page mount. The code below will still delete cats.
