Miao family

• Sagwa Miao (傻瓜 shǎguā, "silly melon") (voiced by Holly Gauthier-Frankel) is the middle of the Miao family, as well as the titular protagonist of the series. Kind, curious, quick thinking, creative and often bossy. She was originally pure white in color but gained her current Siamese cat markings after falling into an inkpot. Sagwa is very talented in calligraphy and is said by her parents to have the best artistic skills in the Miao family. She has a golden-yellow and salmon-red Miao Family collar on her neck. While her name literally means "silly melon", it translates to an affectionate way of calling someone a fool.
• Dongwa Miao (冬瓜 dōngguā, winter melon) (voiced by Oliver Grainger) is the eldest child of the Miao family. Intelligent, competitive and sometimes stubborn, Dongwa is independent and often prefers the company of the Alley Cats or solitary martial-arts practice to playing with his sisters. He is the only male child of this entire family and is also caring of his sisters despite the typical sibling squabbles that occur between them. He is cream-colored and has the traditional Siamese markings and has a purple Miao Family collar on his neck.
• Sheegwa Miao (西瓜 xīguā, watermelon) (voiced by Jesse Vinet) is the youngest child of the Miao family. Curious, friendly, cheerful and full of energy, Sheegwa is also very optimistic and ascribes good intentions to almost every creature she meets. She is pure white in color, except for a pink tinge on her cheeks, and has a folded right ear. She also has a pink Miao Family collar (with a purple flower symbol on it) on her neck.
• Baba Wim Bao Miao (爸爸寶寶 bàba bǎobǎo, "father darling") (voiced by Arthur Holden) is the father of the Miao family. He is very strict with his children, and in matters of hard work and duty, but also has a softer, playful side as well. Baba also fancies himself a devotee of Chinese Opera, although he has Beat deafness. He and Mama are the official calligraphers of the Foolish Magistrate. Baba, like Dongwa, is cream-colored and has typical Siamese facial markings. When Angwan took care of him, she called him Bu-Gu, "Cuckoo Bird". He is also voiced by Bruce Dinsmore in a flashback where he's shown as a younger version of himself.
• Mama Shao Faing Miao (媽媽小風 māma xiǎo fēng, "mother small wind") (voiced by Ellen David) is the mother of the Miao family. Like Baba, she is also a loving but strict parent, but is usually more lenient and gentle than Baba. She and Sagwa have similar coloring and markings.
• Nai-Nai Miao (奶奶 nǎinai, paternal grandmother) (voiced by Sonja Ball) is the grandmother of the Miao family. Grey in color, she is old-fashioned, patient and full of wisdom. She often tells the kittens stories, and the family treats her as a respected ancestor.
• Yeh-Yeh Miao (爺爺 yéyé, paternal grandfather) (voiced by Neil Shee) is the grandfather of the Miao family. Like Nai-Nai, he is wise and patient. He is a good storyteller, and the kittens treat him with great love and respect.
• Uncle Miao (voiced by Neil Shee) is the paternal uncle of Sagwa and Baba's brother. He's very much into ancient local history.
• Mae-Mae Miao is an aunt of Sagwa and Baba's in-law. She and her husband adopt a dog named Cha-Siu. That dog then became a cousin to the Miao kittens.
• Cha-Siu Miao (叉烧 chāshāo, cousin) (voiced by Daniel Brochu) is the adopted child of Uncle Miao and Aunt Chi-Chi, and a cousin of Sagwa, Dongwa and Sheegwa. He is a puppy dog and is different than the rest of the family. Sagwa and Sheegwa are happy to meet him for the first time and immediately bond with him. However, Dongwa isn't sure about him at first because he's a dog and different than everyone else. After the Sleeve Dogs make fun of him for being a dog and not being able to do anything, Dongwa later comforts him and they bond together.
• Chi-Chi Miao (voiced by Susan Glover) is another aunt of Sagwa and Mama's sister. She is an acrobat and teaches Sagwa and Sheegwa the art of acrobatics.
• Uncle Catfish (voiced by Richard Newman) is a mysterious Uncle to the Miao kittens who could also be a first cousin to Yeh-Yeh. He is half cat and half fish who lives in the water. Sagwa visited him once and he told her a tale of his great-grandmother. She was a cat who fell in the water to meet a fish and that made him who he is today.

He occasionally makes rules without reason, or makes ill-conceived decisions under pressure from his wife, Tai-Tai, but for the most part he is portrayed as a just and reasonable ruler. He is very fond of his cats, both for their calligraphy skills and for their ability to keep away mice and rats, of which he is deathly afraid of. In one of the episodes, when he says "No rules, no race.", his phrase turns into a musical drumbeat song as a result of being chanted by him.

She is very attached to the Sleeve Dogs who live in her robe, and values the cats only when they can bring praise to the family. She has a niece called Angwan

They are close friends of the three kittens and do no harm to the Palace nor its inhabitants. However, the Foolish Magistrate and his family are very afraid of mice in general, so their presence must remain hidden.
• Tung (voiced by Thor Bishopric) is a cricket that belonged to the magistrate that lived in a cage in his study. He sang a song that annoyed everyone but the magistrate who loved him.
