''Tailchaser's Song'' is a {{Fantasy}} novel written by TadWilliams and published in 1985. The story follows several feral cat communities, united in their beliefs and by their service to the Queen of Cats residing at Firsthome, the ancestral birthplace of Catkind.

The cats of the novel have their own [[FantasyPantheon mythology]]: they believe that everything was created by a feline god called Meerclar Allmother. The world was originally populated with cats, children of the Two: Harar Goldeneye and Fela Skydancer. Notable among the children of the Two are the three firstborn: Viror Whitewind, Grizraz Hearteater, and Tangaloor Firefoot. Because of his jealousy of his siblings, Grizraz reacts poorly and raises a demon hound to kill everyone. Whitewind succeeds in stopping it, but [[HeroicSacrifice dies in the process]]; later, Tangaloor traps Grizaz beneath a tree. Grizaz, after being trapped underground for a while, is blinded by the sun, and [[BeneathTheEarth digs a hole into the Earth]], where it is said he still remains....

Fast forward, and we meet Fritti Tailchaser, a tomcat in the Meeting Wall Clan. His family [[ConvenientlyAnOrphan mysteriously disappeared]] some time ago, and he was left with no one but his friend, Hushpad. Later, she disappears too. As it happens, quite a few cats have been disappearing, and the Clan Elders send an envoy to Firsthome to ask the Queen for help. Tailchaser is not selected, so he sets out on his own with his lovable friend Pouncequick. Other members of Tailchaser's fellowship are a crazy cat named Eatbugs and Firsa Roofshadow, a sole survivor of a cat massacre.

Tailchaser's Song also has its own brand of Creator/TSEliot-inspired honorifics. They are born with their "heart name" (equivalent to the Japanese first name--such as Fritti, Tangaloor, Firsa, etc.) that only family, close friends and lovers can use. They are appointed a "face name" at an old enough age (equivalent to the Japanese last name--Tailchaser, Roofshadow, Pouncequick, etc.) which is their commonly used name. They have to discover their third and most special name, their "tail name," by themselves.
!!Tropes evident in this work include:
* BeneathTheEarth: Grizraz.
* BoisterousBruiser: Prince Fencewalker.
* {{Bokukko}}: Roofshadow.
* {{Cloudcuckoolander}}: Eatbugs.
* CreationMyth: "In the Hour before time began, Meerclar Allmother came out of the darkness to the cold earth. She was black, and as furry as all the world come together to be fur. Meerclar banished the eternal night, and brought forth the Two."
* DidNotGetTheGirl: [[spoiler:Fritti finds Hushpad living a plump, comfortable (and, it's implied, spayed) life with humans. He leaves her to return to the cats who still live free.]]
* DrivenByEnvy: Grizraz was jealous enough of his siblings' talents to summon a demon-hound in response.
* DynamicEntry: Quiverclaw and the Firstwalkers first "greet" Tailchaser and Pounce by ''ambushing and kidnapping them''.
* EverybodysDeadDave: Roofshadow returned from a walk one morning to find her entire clan either missing or dead.
* FantasticLightSource: Cats have extremely good night vision; this is depicted in the story as the earth and rocks of the caves appearing to glow.
* FantasyPantheon
* {{Fictionary}}: The Higher Singing of the cats.
* TheFilmOfTheBook: [[http://www.tadwilliams.com/2011/05/tailchaser-the-movie/ Upcoming]].
* GrimUpNorth
* {{Hellhound}}: The demon-hound, Ptomalkum, its briefly-mentioned parent, Venris[[spoiler:, and arguably [[EldritchAbomination the Fikos]]]].
* HeroicSacrifice
* IWillFindYou: Tailchaser to Hushpad
* [[KidSidekick Kitten Sidekick]]: Pouncequick
* LivingLegend: Grizraz Hearteater and Lord Tangaloor Firefoot are both ShroudedInMyth, CrystalDragonJesus, {{Physical God}}s. Tailchaser, by virtue of his adventures and TouchedByVorlons status, is as much a legendary hero as cats can have.
* MeaningfulName: Every cat has one as their face name.
* {{Mooks}}: The Clawguards are mook-ier than the Toothguard or the Boneguard, although they are still incredibly dangerous and violent.
* {{Mythopoeia}}
* NamesToRunAwayFromReallyFast: Grizraz ''Hearteater''. {{Justified}} in that the second, descriptive name of a cat is given to them after they have grown old enough for their personality to become evident, and one imagines the cats would also project this onto their mythic figures.
* [[spoiler: PalsWithJesus: Eatbugs was Lord Tangaloor Firefoot all along. Slightly subverted in that he really was insane at the time.]]
* PowerTrio: Tailchaser, Pouncequick, and Roofshadow
* ProperLady: Hushpad seems to be the cat version of this.
* RoyalsWhoActuallyDoSomething: Fencewalker. If only the same could be said for his parents.
* ShoutOut: To ''[[Creator/TSEliot Old Possum's Book of Practical]] {{Cats}}'' (feline naming conventions) and ''Literature/TheElricSaga'' (the cat goddess is named "Meerclar").
* [[SpiritualSuccessor Spiritual Ancestor]]: To ''Literature/WarriorCats''.
* TalkativeLoon: Eatbugs
* UnsettlingGenderReveal: In one myth, Firefoot is allured by a beautiful cat who turns out to be a neutered tom (such a thing was unheard of at the time).
* WarriorPrince: Prince Fencewalker
* WiseBeyondTheirYears: Pouncequick, after his ordeal in the mound and his [[spoiler: time with Whitewind.]]
* {{Xenofiction}}
