The neighborhood's alpha cat. 8-year-old male. A stray who is called whatever the residents like, such as "Nyantaro" or "Nekosaburo." He has a large build and face, is a skilled hunter, and primarily eats local mice and pigeons. Neutered. Though he looks intimidating due to his size and sharp gaze, he is polite, caring, and surprisingly mild-mannered.

A beautiful Siamese cat. 5-year-old female. Owned by the neighborhood's oldest resident, Grandma Kiyo. Since Grandma Kiyo has difficulty moving, Grace is an independent cat who takes care of herself. Her name comes from Grandma Kiyo, who was so impressed by her noble beauty that she named her after Grace Kelly. Noble and intelligent, Grace is deeply compassionate and cannot ignore those in trouble, making her a bit of a pushover. Her hobby is watching morning dramas and music shows with Grandma Kiyo; she can operate the remote freely with her dexterous paws.

A ginger tabby cat. 4-year-old male. Neutered. Cheerful, curious, and very friendly. He is social and visits various houses, making him an informant who knows exactly where the Churu treats are hidden in every home. He found himself wearing a collar one day, but he isn't a specific house cat; he chooses his favorite sleeping spot in whichever house he feels like that day. He has a crush on Grace but is ignored by her.

Six-month-old twin kittens. The whitish one is Momo (female) and the blackish one is Nono (male). Strays.

Besides Boss, they are very attached to Grace, who acts as a good mentor and disciplines them.

A black cat, age and gender unknown. A lone wolf who loves solitude but is never aggressive. Extremely fast and elusive, rarely encountered, but always shows up for the cat meetings.
