Looney Tunes - A Street Cat Named Sylvester (1953)

A Street Cat Named Sylvester is a 1953 Warner Bros. Looney Tunes animated short directed by Friz Freleng. The short was released on September 5, 1953, and stars Tweety and Sylvester.
The title is a play on A Streetcar Named Desire, a play later made into a film.
Notes:
Hector has yellow fur in this cartoon, in contrast to his other appearances where he has light grey fur, perhaps in order to distinguish him from Spike, another Friz Freleng bulldog who has a similar physical appearance to Hector. This would happen again in "Greedy for Tweety".
Granny remains completely unaware of Tweety's presence throughout this entire cartoon, unlike most Tweety and Sylvester cartoons. This would happen again in "A Bird in a Bonnet".
Sylvester's scream of pain when Hector bashes his leg with a club for the first time would later be reused as a stock sound effect in some modern media, such as in Disney's 1996 live-action remake of 101 Dalmatians, the trailer to Disney's 1997 live-action adaptation of George of the Jungle, and even the Super Mario 64 Beta 1995 video game. It was also used in the Pink Panther short "Pinto Pink".
Sylvester's scream of pain when Hector bites his tail was previously used in "Snow Business" and "Zipping Along" (both were also released in 1953).
MeTV aired a previously unreleased restored print of this cartoon on Saturday Morning Cartoons. This was later released 29 June 2021 on HBO Max in Latin America and Brazil.

Censorship on TV:
On ABC, the end where Sylvester is laid up with injuries had the scene of Hector bashing Sylvester's broken foot replaced with Tweety mixing additional medicines in Sylvester's bottle (and, despite claims to the contrary, the scene of Tweety lacing Sylvester's medicine with additional medicines wasn't edited).
The Looney Tunes on Nickelodeon version left in Hector bashing Sylvester's broken foot, but cut off Tweety's final line, "That puddy tat's gonna be in an awful pwedicament when that medicine starts to work" and ended the cartoon with Tweety laughing as Sylvester gags and spits out the medicine (possibly to avoid implications that Tweety may have poisoned Sylvester, even though Nickelodeon did not cut Tweety mixing the medicines in Sylvester's bottle).
