Katie

"Life is short, and time is swift."

- Katie

Katie is a yellow kitten with brown hair debuting in who randomly appears in town once the player's gate has been opened and a visitor from another town has been accepted. In and, she wishes to be reunited with her mother Kaitlin. In, she asks the player to travel to a different town. Her Japanese name prior to means "stray child", which has been changed in later versions.

Katie first appears in alongside her mother, Kaitlin, and will appear in the player's town crying and wishes to be reunited with her mother. She will tell the name of the town where her mother might be, which is a town the player had previously visited. The player must go to this town with Katie, in which she and Kaitlin will be reunited at the Town Gate of the other town. Katie walks slower than the player and may get left behind or fall and cry. Upon doing this, she and Kaitlin will thank the player, and after a day, either she or her mother will send the player a present in the mail. If ignored, Katie will leave after a week since she first appeared.

Despite the Nintendo Wi-Fi Connection being shut down as of May 20, 2014, it is still possible for Katie to appear when connecting via DS-to-DS connection.

Katie returns alongside Kaitlin in, though her role in this game is not that different from her role in. She will still appear in the player's town and ask to be reunited with her mother in a town the player had already visited. Afterwards, she or her mother will send the player a present in the mail.

Due to Nintendo Wi-Fi Connection being shut down as of May 20, 2014, it is no longer possible to encounter Katie in town, and the presents she gives to the player are unobtainable.

Katie returns in, though she is now alone and wishes to see the multiple towns of the world, telling the player that she wants them to take her to the player's friend's town. Unlike the previous games, it can be any town. She may also say which towns she has previously visited. The player must then guide her to the Train Station and take a train with her. After exiting the train, Katie will mention that the main reason she decided to follow the player to the other town is that she is uncomfortable traveling alone. A day later, she will give the player a thank-you present. Katie no longer falls down and cries, indicating her maturity.

There is a possibility, especially if the destination town has already received Katie on the same day, that Katie may drop her ticket upon boarding the train, causing her to jump off the train and pick it up. This event causes the player to leave her behind; however, the player will still receive a thank-you present from Katie the following day, saying that she just took the next train.

If ignored, Katie will stay in the player's town for the whole day.

Although Katie does not appear in, can be obtained from Nook Shopping after attempting to invite her to Photopia via her amiibo.

In, Katie appears as the host of the Fruit Party with Katie Garden Safari event from May 4, 2018 to May 14, 2018.

In 2019, Katie returns with different clothing. If the player orders Katie's Sakura Swing for 350 s (available from March 25, 2019 to May 24, 2019) and places it to their campsite or cabin, Katie will sit here and occasionally swinging. She also host another Garden Safari event Katie's Time Out from March 29, 2019 to April 9, 2019.
