Katie is a lost kitten who comes to your town after you visited a friend's town.
You find Katie crying for her mommy in your town once you went to a friends town. Your friend will have her mom Kaitlyn.
If you want to reunite Katie and her mom, simply ask your friend to open his gate. Katie will follow you there and then Katie and her mom are back together! Whoever has Katie gets a present but whoever found Kaitlyn won't even though they were part of the process.
