Sylvester the Cat and Tweety Bird are two of the most well known characters in the Looney Tunes and Merrie Melodies stable. They had dozens of cartoons together, with Tweety encountering Sylvester at least 48 times during their heyday.Obviously, these shorts have achieved much popularity, second only to the big three stars of Looney Tunes. One version of the classic series The Bugs Bunny Show even gave Tweety Bird top billing along with Bugs in "The Bugs Bunny and Tweety Show". They were even popular enough to get their own TV Spin-Off, The Sylvester and Tweety Mysteries. Tweety also recieved his own Direct-to-Video movie, Tweety's High Flying Adventure.Nowadays, the characters aren't quite as active, but are still a central part of the Looney Tunes cast, currently making appearances in The Looney Tunes Show.

- Angry Guard Dog: Sylvester was constantly at the mercy of a large bulldog (collectively referred to as Hector in later media). In some cartoons he is directly intent on protecting Tweety.
- Anti-Villain: Sylvester.
- Art Evolution: Tweety originally was a pink, featherless baby bird, but the Hays Office insisted that he don a yellow feather coat, due to objections of Tweety being "naked"—and yet they had no problems with Porky Pig not wearing pants!
- Nor did they have any problems with Bugs, Daffy, and various other Warner Bros. and non-Warner Bros. characters who suffered the same thing. The reason it was so glaring with Porky, however, was likely because he actually wore some clothes, and didn't even have the excuse of feathers or fur to cover his lower body. A possible reason the Hayes Office didn't object may have been the fact that Porky was created at a much earlier time.
- In his initial appearences Sylvester was intended to resemble a baggy-pants comedian with a round belly, a low sagging pair of hips and an overly large red nose. This was toned down later, as the early design was hard to animate.
- Ascended to Carnivorism: One short in which Sylvester and Tweety are Snowed-In features a mouse who hasn't eaten in so long he "forgot what food looks like." He takes one look at Sylvester and decides to have him for dinner.
- Beware the Nice Ones: Tweety. Space Jam even demonstrated that he can still slip into this time and time again.
- The Big Bad Wolf: In Red Riding Hoodwinked, Sylvester the Cat teams up with the Big Bad Wolf so that he could get at Tweety Pie, whom Little Red Riding Hood brings to her grandmother. Of course, the Big Bad Wolf is constantly forgetful of Little Red Riding Hood's name and gets prompted by Sylvester from time to time. However, Little Red's grandmother is no pushover, as she knocks both the Big Bad Wolf and Sylvester off the bus she's driving at the end of the story.
- Big "Shut Up!": Sylvester was particularly fond of an obnoxious "AAHHHHH, SHADDUP!!!", most often to Hector barking furiously at him.
- Black Comedy: Used unabashedly in "Satan's Waitin'".
- Breakout Character: Both Granny and the bulldog character (later coined as Hector) made occasional appearances in initial shorts, and gradually became as much mainstream as the main duo. They are near equally prominant in The Sylvester and Tweety Mysteries.
- Bully Bulldog: Hector Depending on the Writer. In some instances he just wants Sylvester to leave Tweety alone.
- Bullying The Dragon: Sylvester frequently tries to get cheap shots at Hector whenever he seems to get the upper hand. These nearly always end with a mauling.
- Perhaps the most glaring case happens in "Tweet Zoo", where Sylvester 'beams a caged lion roaring at him and yells at him to pipe down. Guess how secure that cage is....
- The Cameo: Tweety has a cameo in the Claude Cat/Frisky Puppy short "No Barking", and two of them in Who Framed Roger Rabbit.
- Sylvester, or a cat looking just like him, appears as "Pussycat Puss" in "The Great Piggy Bank Robbery''.
- Comedic Sociopathy / For the Evulz: When Sylvester appeared without Tweety, he sometimes was made a helpless victim of an evil Villain Protagonist. In "Tree for Two", two dogs decide to beat up Sylvester for no reason, although the big one at least gets his comeuppance when he encounters a wild panther instead of Sylvester. Even more disturbing as far as victimization of Sylvester goes is the unpleasant "Canned Feud". In this one, Sylvester's owners go on vacation and forget to put him out. Sylvester finds a cupboard full of canned cat food—but the only can opener is in the possession of an evil mouse, who denies Sylvester the can opener for no damn reason, presumably to starve him to death.
- It should be noted that, unlike other variations of the chase formula such as Tom and Jerry (where the cat was frequently granted Laser-Guided Karma when the victim rather than the bully) Sylvester nearly always lost, whether his protagonist instigated the feud or not. Ironically the few times he was the victor of the short was when he was dishing out the Comedic Sociopathy (eg. heckling Porky or Elmer in cartoons such as "Kitty Kornered" or "Back Alley Oproar").
- Crouching Moron, Hidden Badass: Granny is seemlingly harmless, but is much smarter and stronger than she looks.
- Demoted to Extra: Tweety became less active in later shorts, the main bulk of which revolved more around a bodyguard or alternate adversary guarding him from Sylvester (usually Granny or Hector).
- Determinator: In his pursuit of Tweety, Sylvester takes a licking and keeps on ticking.
- Died Happily Ever After: Sylvester, who gets the last laugh on his foes in the afterlife in "Back Alley Oproar" and "Mouse Mazurka".
- Dude Looks Like a Lady: Given Tweety's falsetto voice, many are the people who still don't know he's a boy. Despite that he's been seen swooning over women.
- It doesn't help in almost every foreign-language dubbed version, Tweety is voiced by women who sometimes don't bother to make him sound remotely male.
- Nor does it help that one of the cartoons is titled "Ain't She Tweet".
- Thanks to Tweety's notorious history of this, The Looney Tunes Show decided to make a gag out of giving him an Ambiguous Gender. Sylvester doesn't even know what gender Tweety is until he's told in a whisper, at which point he exclaims, "I was wrong!"
- In an episode of The Sylvester and Tweety Mysteries Tweety flies into a bird house restroom labeled, "Men". Tweety sticks his head out briefly to explain, "See, folks! I am a boy!"
- Early-Bird Cameo: A bird identical to Clampett's Tweety in all but voice appears in "Wacky Blackout". There are also several early shorts which are considered to have prototypical versions of Sylvester.
- Early Installment Weirdness: Tweety in his earliest appearances was a sadistic trickster who actively fought back against his aggressors. Although Friz Freleng initially went with this characterization in his own Tweety cartoons, Tweety became a genuinely innocent, very passive character later on.
- Played with for Sylvester. His character was pretty much fully developed in his first appearance in "Life With Feathers" however as other directors took shots at the character he went through several different directions before returning to his original characterisation. Bob Clampett portrayed him as an extroverted Screwy Squirrel in "Kitty Kornered", while Art Davis used a dopier, more deadpan variant.
- Escaped Animal Rampage:
- Many cartoons have Hippety Hopper, a kangaroo, escaping from the zoo, causing Sylvester and his son to think that he is actually a large mouse.
- One of these cartoons had a panther escape from the zoo, just as a Bully Bulldog is chasing Sylvester. Hilarity Ensues when he mistakes the panther for Sylvester.
- Fire and Brimstone Hell: As seen in "Satan's Waitin'".
- Flanderization: Tweety started out as a character that was cute but violent and hilarious at the same time in Bob Clampett Tweety cartoons. Although Friz Freleng's first few Tweety cartoons, like I Taw a Putty Tat (1948), retain that same flavor, the little yellow bird gradually became a character that played cute only for the sake of being cute.
- Gone Horribly Right: In one story, Sylvester paints a white stripe on his back so the dogs guarding Tweety will mistake him for a skunk and flee. He does scare the dogs away but now has to put up with Pepe Le Pew.
- Harmless Villain: Sylvester, at least in the shorts with Tweety.
- Hidden Depths: Despite Tweety becoming softer, fans still speculate that he's still a sadistic being on the inside who takes pleasure in seeing Sylvester get hurt.
- Invincible Hero: Tweety. Though he had a slightly more vulnerable streak than most other Looney Tunes protagonists, he was one of very few to come out the victor in every appearance he made.
- Let's Get Dangerous: Surprisingly enough, despite his Chew Toy status, Sylvester got himself a moment of utter badassitude in "Scaredy Cat". After barely escaping the killer mice inhabiting the diaplidated old mansion Porky Pig has bought, and more or less deciding "Screw This, I'm Outta Here!", his conscience appears to him and reminds him of how Porky raised him from a kitten, and then of "the difference in size between a cat and a mouse", prompting Sylvester to grab an entire log and run off to take on all the mice despite their murderous nature. And he wins.
- Light-Flicker Teleportation: "Greedy For Tweety" did this: Sylvester is in a hospital bed and can't move, having been given sleeping pills. Every time he opens and closes his eyes, the dog appears closer and closer, wielding a club. It's prime Nightmare Fuel.
- Long Runner
- Motive Decay: Later cartoons put more spotlight on a protective bulldog (later named Hector in Sylvester And Tweety Mysteries) who guarded over Tweety. As such more emphasis was put on Sylvester trying to dispose of the dog to reach Tweety. Some cases evolve more into a vengeful Escalating War for his constant pummellings that he seems to forget about going after Tweety (eg. "Greedy For Tweety").
- Musical Episode: "I Tawt I Taw A Puddy Tat", a modern CGI short that essentially acts a music video for one of Mel Blanc's old Capitol records.
- Never Mess with Granny: Might very well be the Trope Codifier.
- Nice Mice: Usually played straight against Sylvester with characters such as Speedy. Exceptions occur in cartoons such as "Canned Feud" and "Claws for Alarm", where Sylvester is tormented by sociopathic vermin for no established reason.
- No Celebrities Were Harmed: Babbit and Catsello from "A Tale of Two Kitties" are shameless parodies of Abbott and Costello. One cat in "A Gruesome Twosome" is a caricature of Jimmy Durante.
- Not What It Looks Like: To avoid being blamed when another cat captures Tweety, Sylvester spent most of the episode trying to rescue Tweety from the other cat. In the end, while Sylvester was placing Tweety back in the cage, Granny reappeared and wrongly concluded Sylvester was capturing Tweety again. Quickly accepting she'd never believe the events prior, he prepares for his trip to the violin factory.
- Pet Heir: Sylvester is left a fortune (and all of its attendant problems) in "Heir-Conditioned".
- Ping-Pong Na´vetÚ: Just how innocent Tweety is in his dealings with Sylvester is part of the gag. Granny's awareness of Sylvester antagonizing Tweety also varies from short to short.
- Pint-Sized Powerhouse: Tweety in his earlier appearances, particularly the Clampett films.
- Punny Name: Tweety is sometimes referred to fully as "Tweety Pie" due to the cartoon of that title (a play on his speech impediment).
- Satan: A bulldog version of him appears in "Satan's Waitin".
- Suddenly Shouting: Tweety in "Birdy and the Beast".Tweety: Aw, da poor putty tat. He faw down an' go BOOM!
- The Golden Age of Animation
- Team Rocket Wins: Sylvester never won against Tweety, though he got the last laugh in a handful of alternate appearances. He succeeded in eating an Asshole Victim parrot in "Catch As Cats Can" and outwitted Porky in throwing him out for the night in "Kitty Cornered".
- Threatening Shark: Towards Sylvester, that is, in the latter-day short "Hawaiian Aye Aye", who tries all he can to keep Tweety safe.
- Villain Protagonist: Sylvester, in his shorts with Tweety and Hippity Hopper.
- Villainous Underdog: While Sylvester certainly isn't weaker than Tweety, he's no match for Granny or Hector and has to find ways to sneak past them in order to get at the bird. That's without getting into his fights with Speedy Gonzales or Hippity Hopper.
- Wartime Cartoon: "A Tale of Two Kitties" has a Victory Garden appear, Tweety sics Anti-Aircraft cannons on Catsello in the ending, and tells the duo to TURN OUT THOSE LIGHTS.
