Kitten

Kittens are a species of small cats that appear in Bowser's Fury. They can be seen on most of the various islands composing Lake Lapcat. They exist in five different colors: green, red, blue, black, and, each representing the different colors of the  (lucky cat). The former four also match the Cat form colors of the playable characters in Super Mario 3D World other than Mario: respectively Luigi, Peach (although using a deeper shade of pink similar to Toadette's Cat form), Toad, and Rosalina.

Kittens can be seen relaxing, grooming themselves, or playing with baseballs in various spots in Lake Lapcat. They are friendly, and follow and affectionately nuzzle Mario if he is in his Cat form. If Mario approaches them in any other form, however, they become frightened and try to avoid him. They can also be picked up and carried by Mario. While being carried, they will continuously scratch in front of them, which can destroy Brick Blocks and activate ? Blocks, similarly to Cat Mario's scratch. If a kitten makes contact with water or lava, it will vanish and respawn at its original location. If Mario or Bowser Jr. attack a kitten, it does not take damage, and confetti appears instead.

Although the plain-colored kittens are not related to any game objective, the calico kittens are missing offspring of calico cat parents that must be returned to them for Cat Shines. There are nine calico kittens across Lake Lapcat: one near the Lakeside Giga Bell, three near the Ruins Giga Bell, and five near the Wasteland Giga Bell. Some are located close to their parent, while others require Mario to carry them a great distance back.

After beating the game once, Cat Plessie becomes able to carry kittens if Mario throws them on top of it or mounts it while holding one, allowing them to travel to different islands. However, calico kittens cannot ride Plessie, and must be delivered to their parent by Mario.

In the game's ending, a blue, a pink, and a green kitten circle around Cat Mario. The blue kitten nuzzles Mario, and the pink kitten licks its paw. The three kittens and Mario then jump up into the air.

Excluding calico kittens, there are 41 kittens in total: four near the base of Scamper Shores, four on a higher hill in the same area, four in a tunnel behind Fort Flaptrap, four near the lighthouse of Pounce Bounce Isle, four near the lighthouse on Roiling Roller Isle, four on Mount Magmeow, three at the top of Pipe Path Tower, and fourteen around the Wasteland Giga Bell.

While Fury Bowser is active, all kittens become corrupted and attack Mario, regardless of his form. If Mario is holding a kitten when Fury Bowser wakes up, then it will damage him and leave his grasp. If a kitten is riding Plessie when Fury Bowser wakes up, then it will teleport back to its original location.
