Sylvester The Cat

Sylvester is a cat who appears in several Looney Tunes cartoons, often chasing Tweety, Speedy Gonzales, or Hippety Hopper.

Voice
Sylvester's trademark was his sloppy, stridulating lisp (which, like Daffy Duck's, was based on producer Leon Schlesinger's). His sloppy voice was provided by voice acting legend Mel Blanc. Blanc reveals in his autobiography that Sylvester's voice and Daffy's were identical, but Daffy's was sped up in post-production.

In Space Jam, Sylvester was voiced by Bill Farmer who is famous for doing Disney's Goofy & Pluto.

Personality and Pride
Sylvester shows much pride in himself, and he never gives up. Despite (or perhaps because of) his pride and persistence, Sylvester was definitely on the "loser" side of the Looney Tunes winner/loser hierarchy. His character is that of Wile E Coyote, except that the roadrunner and coyote are a parody of the cat and mouse pairings. He shows a different character when paired with Porky Pig in explorations of spooky places, in which he doesn't speak, as a scaredy cat. (In these cartoons, he basically plays the terrified Costello to Porky's oblivious Abbott.) Sylvester's most developed role is as hapless mouse-catching instructor to his dubious son, Sylvester Junior, in which the "mouse" is a powerful baby kangaroo. His alternately confident and bewildered episodes bring his son to shame, while Sylvester himself is reduced to nervous breakdowns. He is often referred to as a putty tat by Tweety and Senor Gringo Pussy gato by Speedy Gonzales. In the cartoons he usually gets clobbered by Granny or Hector the Bulldog whenever he tries to eat Tweety.

Freleng Shorts
Sylvester's first appearance with Tweety was in the 1947 short Tweety Pie where he tries to eat Tweety but gets punished. The pair's cartoons lasted from 1947 to 1964, shortly before the closure of the Warner Bros. studio. Sylvester and Tweety became one of the most well known pairings in Looney Tunes, next to Bugs and Daffy. Some of their cartoons have won an Academy or were nominated.
