Kitty Is Not a Cat

Main

• Kitty (voiced by Roslyn Oades) – The titular heroine who is not a cat. She has black hair and wears an orange cat costume with a red collar. Her skin is white, with light maroon cheeks on her face. She is an orphan. Her origin or how she found out about the mansion with the talking, smart & musical cats remains a mystery.
• King Tubby (voiced by Rove McManus) – A fat black tuxedo Persian cat. He has black fur and wears a red collar and a tin can for a crown. Self-appointed "king of all cats", Tubby spends most of his time "sitting on his throne, pretending he knows just what's going on". He however regularly provides explanations on certain aspects of humanity, albeit shaky ones. Oddly, he doesn't seem to play any musical instrument.
• The Nazz (voiced by Stephen Hall) – A dark orange Norwegian forest Persian fox-cat. Maybe the oldest cat in the mansion, The Nazz is also the sanest, wisest, and most responsible one, who tries to keep a semblance of order. He's a talented and experienced piano player who composed and recorded several albums' worth of songs. The Nazz barely appears in season 2, only having two episodes in total where he provides a speaking role, and the rest of his appearances are non-dialogue cameos where he is not in focus; his role as a father figure to Kitty in the show is completely taken over by Ming. The Nazz is then completely absent from the show in season 3.
• Petal (voiced by Cal Wilson) – A Russian Blue cat, who's soft-spoken, calm, takes great care of others, but knows how to be firm when needed. She is considered a mother figure for Kitty, keeping her safe and teaching her the values of kindness, diligence and patience. She plays the saxophone.
• Timmy Tom (voiced by Rachel King) – A light blue tabby cat. The youngest of all the cats, Timmy is almost always seen in Kitty's company, and they always get along wonderfully. He can still play a few instruments, notably pianos.
• Miley (also voiced by Rachel King) – A light pink tabby cat. She has pink fur with a light pink belly and wears glasses. A brilliant, snarky, sour loner, Miley is usually seen reading a book or cultivating her individuality. She has a well-hidden soft spot for Kitty, which doesn't stop her from expressing her criticism in her idiosyncratic way. She can use a keyboard, but her specialty is samples, synthwave and electronic music.
• Cheeta (also voiced by Rove McManus) – A cyan Siamese cat, no one is ever sure if what is going to come out of Cheeta's mouth, be it a creative piece of advice, or some more nonsensical solutions that will likely make the problem worse. Still, he sometimes has good (if unusual) ideas, and plays the electric guitar.
• Ginsburg (voiced by Vincent Milesi) – A cyan tabby cat. Little is shown about Ginsburg, safe from the fact that he is usually not very quick, likes to end his sentences in "Man", and is an incredible drummer.
• Pierre (voiced by Rupert Degas) – A cyan tabby cat. Refined, elegant, and French, Pierre is the mansion's cook and plays the bass.
• Ming (also voiced by Rupert Degas) – A Balinese persian cat. Scary, cold and distant, Ming behaves like an inscrutable [[Science fiction film|sci-fi B movie villain. He's always had very ambivalent feelings towards the mansion's new resident. He plays keyboards in a very personal manner. By season 2, he is considered a father figure to Kitty, teaching her valuable lessons about life, morals and the value of humanity.
• Mr. Clean (also voiced by Rupert Degas) – A Maine Coon-Manx cat. Small, dirty, and simple, Mr. Clean is a humble cat who is very satisfied with his own hygiene. He's been shown to know how to grow fruit and vegetables, and, he plays the tuba.
• Happy (also voiced by Rupert Degas) – A Chartreux eyes-closed cat, Happy would have a hard time seeing his own paws, but this handicap has resulted in a unique character trait: since he can't see the bad in anything, then everything is amazing to him all the time! He provides lighthearted comic relief and plays the trombone.
• Last Chance (also voiced by Rove McManus) – An injured green tabby cat. Everyone knows cats have nine lives. Last Chance is on his, well, last one, but he isn't going to let this bring him down. He plays the trumpet, and announces King Tubby's arrivals and house meetings.
• Thorn (also voiced by Cal Wilson) – A black and white Sphynx cat. She has black fur with a white muzzle and belly. She wears a red collar around her neck. She also wears a pair of white boots. Dark, menacing, classy, and cold, Thorn may seem scary, but has shown more many times how deeply she cares for little Kitty. She is an impressive singer, speaks with a Russian accent and has a twin sister named Rose (also voiced by Wilson).
• Spook (voiced by Jamie Aditya) – An Abyssinian-Munchkin cat who is afraid of spiders, Spook perfectly illustrates the expression "scaredy cat". He's terrified, startled, or worried by nearly everything, but finds comfort in a sappy romance television show, and apparently has a knack for technology. He doesn't play instruments, but knows his way as a disc jockey.
• Luna (also voiced by Rachel King) – A brown-haired tabby cat, Luna tries to avoid effort whenever possible, except when music and dancing are involved. She plays the zither.

Recurring

• The Mice (both voiced by Jamie Aditya) – a pair who work for King Tubby and wheel him out of places, which they don't do happily. They frequently complain about how they aren't given a break.
• Harold Stinkleton (voiced by Rupert Degas) – One of the neighbours. He is grumpy, clueless, and submissive towards his wife.
• Olive Stinkleton (voiced by Rachel King) – One of the neighbours. She is prissy, haughty, and bossy towards her husband.
• Stanley "Stan" Stinkleton (voiced by Marg Downey) – The youngest Stinkleton. He is usually depicted playing video games, eating, sleeping, and doing as little of worth as possible.
• King Tubby's Mom (voiced by Rove McManus) – A fat black tuxedo Persian cat. She is the mother of King Tubby.
