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 
 * 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.

Relationships 
 * 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.
 * Pouncival: might be brothers.
 * Tumblebrutus: might be brothers.
 * Victoria: In some productions they dance the Mating Dance together. Might be mates, or his adopted sister. (See Platoria)

Alonzo
Theories 
 * London-based Alonzo is a black and white spotted cat
 * 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.
 * 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 may be acting tough to win over some of the queens.

Relationships 
 * Asparagus: might be Alonzo's father.
 * Bombalurina: might be mates.
 * Bustopher Jones: might be Alonzo's father, uncle, or brother. 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.
 * Cassandra: might be mates - this is indicated onstage in UK-based productions. (See Alondra)
 * Demeter: might be mates - this is indicated onstage in Broadway-based productions. (See Demelonzo)
 * Electra: might be mates, or she might be his daughter.
 * Etcetera: might be mates.
 * Grizabella: might be Alonzo's mother.
 * Jellylorum: might be Alonzo's mother.
 * Jemima: might be Alonzo's mate or sister.
 * Macavity: might be Alonzo's brother.
 * Mistoffelees: might be Alonzo's brother, friend, or mate. (See Alonzoffelees)
 * Munkustrap: might be Alonzo's brother, son, or mate. (See Alonzostrap)
 * Old Deuteronomy: might be Alonzo's father.
 * Pouncival: might be Alonzo's brother.
 * Rum Tum Tugger: might be Alonzo's brother, or mate. In the 2016 revival, he takes Mistoffelees' classic line, calling him a "Terrible bore" along with Munkustrap, and doesn't seem to fall for his charms. (See Altugger)
 * Alonzo is the father of Sillabub and raised her with the help of Jennyanydots and Skimbleshanks.
 * Tumblebrutus: might be Alonzo's brother.
 * Victoria: might be Alonzo's mate or sister. In some productions they dance the Mating Dance together.

Asparagus / Gus
 Theories 
 * Asparagus is a long-haired sandy tabby.
 * In the film version, Asparagus is a separate character from Gus the Theatre Cat. Most fans consider them separate, Asparagus in the ensemble is much livelier and younger than Gus the Theatre Cat.
 * Asparagus is a Libra.

Relationships 
 * Admetus: might be Asparagus' son.
 * Alonzo: might be Asparagus' son.
 * Etcetera: might be Asparagus' daughter.
 * Gus: Might be Asparagus' father or grandfather.
 * Jellylorum: might be mates, or siblings. (See Guslorum)
 * Jennyanydots: might be mates, or siblings.
 * Mistoffelees: might Asparagus' son or adopted son.
 * Plato: might be Asparaguss' son.
 * Pouncival: might be Asparagus' son.
 * Skimbleshanks: might be siblings.
 * Tumblebrutus: might be Asparagus' son.
 * Victoria: might be Asparagus' daughter or adopted daughter.

Bill Bailey / Tumblebrutus
Theories 
 * Bill Bailey is a tabby and white kitten, with patches of tabby stripes and spots on a white body.
 * Possibly a Burmese cat breed, or a scruffy short-haired alleycat.
 * Bill Bailey/Tumblebrutus is an Aries.
 * His owner may be a gymnast.
 * Tumblebrutus was among the names listed in the poem Growltiger's Last Stand by T.S. Eliot, as Growltiger's first mate in the Raffish Crew. Tumblebrutus is probably an ex-member of Macavity's crew or Growltiger's, though he is surprisingly young. In fact, the poem specifically says "his bosun, Tumblebrutus, he too had stol'n away" meaning that Tumblebrutus was missing the night Growltiger met his downfall, meaning that he probably was involved in betraying his boss.

Relationships 
 * Alonzo: might be brothers.
 * Asparagus: might be his father.
 * Cassandra: might be related or mates (reference to Japanese production)
 * Electra: might be siblings, or mates.
 * Etcetera: might be siblings, or mates.
 * Growltiger : May be his former boss
 * Jellylorum: might be his mother.
 * Jemima: might be siblings, or mates. They are seen dancing together in some productions.
 * Jennyanydots: might be his mother.
 * Macavity : may be his former boss
 * Mistoffelees: might be brothers or close friends.
 * Pouncival: might be brothers or mates. (See Tumblebucketty)
 * Skimbleshanks: might be his father.
 * Tantomile: might be mates, or close friends.
 * Victoria: might be siblings, his adopted sister or mates. (See Tumbletoria)

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.
 * Bombalurina really was Dick Whittington's cat, and because of her heroics she was chosen to be reborn through the Heaviside Layer. She still remains proud of her past life.

Relationships 
 * Alonzo: might be mates.
 * Bustopher Jones: might be a close friend of his, might be a fan along with Jennyanydots and Jellylorum but not so much as she is a fan of Tugger.
 * 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, close friend, or daughter by Macavity or Alonzo (performer Suzie Melloy has shared this theory.)
 * 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)
 * Rum Tum Tugger: might be mates or best friends. Bombalurina flirts with him during his solo, and they dance the pas de deux. (See Tuggerina)
 * Sillabub: might be Bombalurina's niece, daughter, or friend.
 * Skimbleshanks: might be Bombalurina's father.
 * Victoria: might be Bombalurina's daughter.

Bustopher Jones
Theories 
 * 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.
 * Bustopher Jones was a therapy animal in the military. This would explain why he loves food so much, and why he has such status among the Jellicles, and why Munkustrap salutes him.

Relationships 


 * Alonzo: might be his son, nephew, or brother, due to them having the same coat colours.
 * Grizabella: might be his kittenhood friend
 * Jellylorum: might be his mate.
 * Jennyanydots: might be his mate. She is shown to be a great admirer of him in his solo.
 * Mistoffelees: might be his son or nephew, due to them both being tuxedo cats.
 * Tumblebrutus: might be his nephew
 * Victoria: might be his daughter or his niece

Carbucketty / Pouncival
 Theories 
 * Carbucketty is a tabby and white kitten/teen.
 * Carbucketty and Bill Bailey (or Pouncival and Tumblebrutus) are best friends, and one is the youngest kitten in the tribe, the other is older. Which depends on the production.
 * Carbucketty/Pouncival is a Leo.

Relationships
 * Alonzo : might be be brothers.
 * Asparagus : might be Pouncival's father.
 * Bombalurina : 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)

 * Victoria: might be siblings or his adopted sister.

Cassandra
 Theories 
 * Cassandra is some form of exotic breed, possibly Abysinnian, Siamese, Havana Brown, or Burmese.
 * Cassandra is a Capricorn.
 * Cassandra was never meant to be a Jellicle, since her parents were carefully bred exotic cats who didn’t want their daughter on the streets to mate with any motley breed, so she was spayed. But Cassandra was enticed by the carefree Jellicle life, and escaped her home to join the tribe.
 * She really was there when the pharoahs commissioned the Sphinx.

Coricopat


Theories
 * Coricopat and Tantomile are strongly marked Tabby and white. He has less white on his bib than Tantomile. They are almost identical.
 * Coricopat and Tantomile are possibly of the Abysinnian, Burmese, or Somali cat breed.
 * Given that the psychic twins display magical abilities, this suggests they might be related to the other magical cats - Mistoffelees, Macavity, and Jemima.
 * Coricopat is a Gemini.

Demeter
Theories

 * Demeter was once lured into Macavity's world, kept away from her tribe. She was manipulated and abused, her ears torn. During this time, she often saw Grizabella walking the streets, a shambles. On the night of the Jellicle Ball, Demeter escapes from Macavity's lair and heads for the junkyard where she knows the others will meet. We see her arrival at the top of the show when she is revealed by the headlights of a passing car. Thoughout the show, she is very alert and warns of Macavity. She knows he will return for her.
 * Bombalurina and Demeter are sisters, who both were involved in Macavity's gang. Macavity was in an abusive relationship with Demeter.
 * Grizabella is Bombalurina and Demeter's mother, and abandoned them to continue her glamorous lifestyle. Demeter has a lot of empathy for Grizabella, but lacks the confidence to displease Bombalurina by reaching out to her.
 * 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.
 * Demeter is possibly a Somali, Turkish Angora, or mixed cat breed.
 * Demeter is a Cancer. ￼

Relationships


 * Alonzo: might be mates - this is indicated onstage in Broadway-based productions. (See Demelonzo)
 * Bombalurina: 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.

Theories

 * Etcetera has ADHD or isn't neurotypical. The way her movements while fangirling over Tugger is very reminiscent of stimming.
 * Etcetera is one of Grizabella's many bastard children as a results of her promiscuity. Grizabella viewed the young neurodivergent kitten as worthless, and didn't bother to give her a name. Therefore the kitten was dropped in the gutter nameless, and was picked up by the other Jellicles. Because Grizabella thought of her as just something to put at the end of a list, she gave herself the name of "Etcetera"

By luck Mungojerrie and Rumpelteazer managed to avoid Macavity’s influence, and were adopted by Jennyanydots

Grizabella
Theories 
 * Grizabella is a sandy tabby.
 * Babygriz, that we see in the ensemble at the start of the show, is actually Grizabella re-born from the Heaviside layer as an innocent, joyful kitten. She doesn't remember her past but she treasures her youth and beauty. What happens after the end of the show is actually shown in the beginning.
 * Grizabella and Bustopher 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.

 * Grizabella is an Aries.
 * Grizabella may have worked for Macavity at some point which led her to get exiled from the tribe.

 * Grizabella left to chase fame but after receiving an eye injury that left her scarred she couldn't get any roles and became depressed which led to her neglecting taking care of herself.

Relationships
 * Grizabella gave up her kitten Victoria to the tribe, knowing that she couldn't take care of her. Grizabella comes to the jellicle ball for a chance to see her daughter and to be accepted again.
 * Griddlebone, Grizabella, Jellylorum, and Jennyanydots are sisters from two separate litters. Griddlebone and Grizabella were very close growing up and their favorite past time was bullying Jennyanydots.

Macavity
Theories 
 * Macavity is specified as "...a ginger cat, he's very tall and thin"
 * Canon direction says that Demeter and Macavity have a history together, hence why she assumes every threat is him. Macavity is often assumed to have been her abusive partner. Perhaps Jemima is even their child.
 * Given that Macavity has magical abilities such as levitation and teleportation, this has led to the theory he might be related to the other magical cats, Mistoffelees, Coricopat, Tantomile and Jemima.
 * Macavity is a Taurus.
 * Macavity may had been kicked out of the Jellicles which made him angry and took a turn for the worst.

Relationships

 * Munkustrap, Bustopher Jones, Skimbleshanks, Mistoffelees, Victoria, Mungojerrie, and Rumpleteazer are the only members of the tribe to have wealthy owners.
 * Mistoffelees is a Leo or Gemini, this seems plausible since the difference between Mistoffelees during a majority of the show is much different from his flashy, song counterpart.
 * Possibly gay or a drag queen
 * May be on the autisim spectrum. Mistoffelees was mute for many productions making him "non-verbal" which is a symptom for a few people on the autism spectrum.
 * Mistoffelees is actually younger than most people think, as the canon description says. He is said to be the same age or slightly older than Victoria, which is old enough to have not one, but two girlfriends (Victoria and Cassandra), and a boyfriend (The Rum Tum Tugger), which would make Mistoffelees a child prodigy
