As always in cartoons of this era, the attention to background detail is wonderful. Everything from doorways and baseboards to an oil lamp and icicles on the windows, and more. It wasn't called the golden age for nothing!
Tweety and Sylvester are friendly in this short...at first.
Mel Blanc, speaking as Tweety Bird, didn't say his most popular phrase:
"I tawt I taw a putty-tat!", in six cartoons (at-least). In order, they are 01: Qu'importe le Flocon (1953), 02: Heir-Conditioned (1955), (Tweety was in just a 5 to 10 second cameo, as it appears, Tweety was going to be another cat's "dinner to be", he just a one sentence quote). 03: Grand mère ne s'en laisse pas conter (1955), 04: Tweet and Lovely (1959), 05: The Last Hungry Cat (1961) & 06: The Jet Cage (1962). In the fourth cartoon, "Tweet & Lovely", Tweety called Sylvester, "a peeping Tom cat".
Sylvester puts out his smoldering tail in a classic old fashioned pedestal ashtray.
The canned heat used by the mouse is another term for Sterno, a canned cooking fuel. It is still used by cooks and caterers in 2022 to heat chafing dishes.
