Headcanons

This page is for putting any headcanons (your own theories, not officially recognised) relating to the musical and the characters of Cats. Please remember that this is a fanon page. Feel free to add any headcanons you might have, but don't delete other people's ideas.

Where possible, please elaborate on the reasoning behind your headcanons and theories.

General
Jellicle Ball
 * The Ball takes place during a full moon ("The Jellicle moon is shining bright")
 * It takes place during the winter solstice (the opposite of summer solstice), hence why Act 2 was originally titled "Why Will the Summer Day Delay – When Will Time Flow Away?"

Pairings
See Category:Couples for fandom ships.

Admetus / Plato
Theories  Relationships 
 * Admetus is a ginger and white short-haired stray.
 * Plato is a tabby.
 * Admetus and Macavity are in some way linked, perhaps as relations, or a split personality Jekyll/Hyde.
 * Skimbleshanks is Victoria's father, and he arranged the pairing between Victoria and Plato. He did this because he wants only the best for his daughter, and Plato has always seemed like a respectful young tom, but little does he know, Plato is quite shallow...
 * Admetus/Plato is a Leo.
 * Admetus/Plato is Macavity's younger secret brother.
 * Admetus: In productions where there is both Admetus and Plato, such as the movie, they might be siblings.
 * Asparagus: might be Admetus' father.
 * Bombalurina: might be mates.
 * Demeter: might be mates.
 * Etcetera: might be siblings or mates.
 * Jellylorum: might be Admetus' mother.
 * Macavity: might be Admetus' father, brother, or alter-ego.
 * Mistoffelees: might be his brother or adopted brother.
 * Old Deuteronomy: might be his grandfather.
 * Plato: In productions where there is both Admetus and Plato, such as the movie, they might be siblings.

 * Broadway-based Alonzo is a tabby alley cat.
 * Alonzo is possibly a black and white Turkish Van or a British shorthair due to the texture coloring of the coat.
 * Alonzo is Bustopher Jones' nephew, (hence the similar colorings) but because he's a scrappy alley cat, Bustopher doesn't want to acknowledge him as family.
 * To add on to this, in the film, when Alonzo saved Demeter from Macavity, his motive might have been his mother. Maybe his mother was in an abusive relationship, that's how he was born, and this is why Bustopher shuns him.
 * Alonzo is a Scorpio.
 * Alonzo is the father of Sillabub and raised her with the help of Jennyanydots and Skimbleshanks.
 * Asparagus: might be Alonzo's father.

 * Victoria: might be Alonzo's mate or sister. In some productions they dance the Mating Dance together.

Bombalurina
Theories 
 * Bombalurina is a bright Torbie and white - her ginger colour exaggerated onstage, but she has patches of black stripes over a bright ginger, and a white bib.


 * Bombalurina and Demeter are sisters, who both were involved in Macavity's gang. Macavity was in an abusive relationship with Demeter, leading to conflicting emotions for Bombalurina.
 * After Demeter left Macavity's gang, Bombalurina was the first cat to welcome her to the Jellicles. That's why she's so protective of her.


 * Grizabella is Bombalurina and Demeter's mother, and abandoned them to continue her glamorous lifestyle. She inherited her looks and confidence from her mother, and she understands her but resents her abandoning them.


 * Bombalurina is possibly a Somali cat breed.
 * Bombalurina is a Cancer or a Leo.

Relationships 
 * Alonzo: might be mates.

 * Coricopat: may be her son with Macavity his father.
 * Demeter: There is much debate about the relationship between these two. There is speculation that they might be sisters, mother and daughter, mates, or close friends. Depending on the age of each cat in the production, Demeter may be seen as Bombalurina's mother or vice versa. (See Demelurina)
 * Electra: might be Bombalurina's cousin, younger sister, or close friend.
 * Grizabella: might be Bombalurina's mother.
 * Gus: might be a relation of Gus the Theatre Cat.
 * Jennyanydots: might be Bombalurina's mother.
 * Macavity: There is debate about the relationship of these characters. Fans speculate that Macavity may be Bombalurina's father, brother, or mate. What is for sure is that Bombalurina knows a lot about Macavity, and is less afraid of him than Demeter is.
 * Mistoffelees: might be Bombalurina's son.
 * Munkustrap: might be mates.
 * Pouncival: might be mates. Pouncival is seen flirting with Bombalurina during the end of The Rum Tum Tugger number, in addition to being paired up during Victoria and Ademetus/Plato's section of the Pas De Deux. (In reference to the 1998 film)

Bustopher Jones
Theories  Relationships 
 * Bustopher Jones is a well-fed, plush black short-hair, with a white bib and white paws (his white "spats")
 * Bustopher Jones is possibly a British or Exotic Shorthair or an oversized Bombay cat breed.
 * Alonzo is Bustopher Jones' nephew, (hence the similar colorings) but because he's a scrappy alley cat, Bustopher doesn't want to acknowledge him as family.
 * To add on to this, in the film, when Alonzo saved Demeter from Macavity, his motive might have been his mother. Maybe his mother was in an abusive relationship, that's how he was born, and this is why Bustopher shuns him.
 * Mistoffelees is also Bustopher's nephew, but because he's a purebred tuxedo cat, and has been well educated and lives with a wealthy family, Bustopher takes great pride in being his uncle.
 * Bustopher and Grizabella have had a closet friendship since they were kittens. But, when Grizabella was kicked out of the tribe, she stopped talking to Bustopher because he was an important cat within the tribe. Grizabella lives in an alley not far from the Tomb. This is why Bustopher "looks full of gloom" whenever he's eaten there. It's because he misses the good times he and Grizabella had as kittens. It has nothing to do with the food; he actually loves cabbage, rice pudding, and mutton.
 * Bustopher Jones is a Sagittarius.
 * Munkustrap, Bustopher Jones, Skimbleshanks, Mistoffelees, Victoria, Mungojerrie, and Rumpleteazer are the only members of the tribe to have wealthy owners.

 * Tumblebrutus: might be his nephew
 * Victoria: might be his daughter or his niece

Carbucketty / Pouncival
 Theories

 * After Demeter left Macavity's gang but before she joined the Jellicles, she met Grizzabella. They helped each other out while they were living on the streets, but Demeter left her behind after she met Bombalurina and was welcomed into the Jellicles. That's why she knows so much about her during Grizzabella the Glamour Cat, and why she wants to reach out to her but doesn't; she's scared of loosing her place with the Jellicles.

Theories
