Installation is very easy.
Once you register the program it unlocks some of the features but, you have to wait seven to ten days until your CD or Floppies arrive via snail mail to get all of the features up and running. You also have the option to let it roam over your desktop. Over time the kitten grows into a full grown cat and actually develops its own unique personality depending on how you treat it. One is skittish, another is somewhat aggressive and so forth. Another feature is a built in screen-saver with optional password protection.
