Cat Chat was released with out giving you the information on how to get the menu. In order to get the menu when the cat chat is on touch the back, legs or base of the cat. If you like to get any of the random messages from the cat simply touch its face or ears or tail.

As this is a feature update and not a critical update it is not necessary to update unless you want to partake in the new feature.
