I remember that I originally saw "Hyde and Go Tweet" in the compilation film "Daffy Duck's Quackbusters", but now I've finally gotten to see it in its own form. I actually derive that there's more to it than simply being a cartoon. Early on, Sylvester - after nearly falling off the ledge on the side of a building when he tried to catch some birds - says "Being a pussycat is a constant hazard." Less than a minute later, Tweety - having shakily landed on the ledge - says "They still haven't perfected flying." That's when Sylvester chases Tweety into a science lab, where Tweety jumps into Hyde formula; the rest, as they say, is history.
It's interesting to think that, despite their evident antagonism towards each other, Sylvester and Tweety appear to live somewhat parallel existences in this respect; obviously, things become more dangerous for them as they chase each other back and forth throughout the cartoon. Maybe if they both came to understand how unsafe life is for each other, they wouldn't be enemies.
Of course, I mean all that figuratively/metaphorically. But there is yet another topic that the cartoon brings up: cowardice. He was lucky that he was a civilian and not a soldier, because had that been cowardice in the face of the enemy during wartime...well, just watch Stanley Kubrick's movie "Paths of Glory" and you'll see what I mean.
I'm probably reading too far into this cartoon. It was most likely intended as pure entertainment, and it does come out pretty entertaining. Worth seeing.
