Whether this was a rip-off of the Tweety-and-Sylvester 'toon called "Kitty Foiled" or not was immaterial to me once I watched this because this was outstanding. (So was "Kitty Foiled.")
The sight-gags, pratfalls, slapstick nonsense, etc., were almost all very clever in this short as Tom tries one thing after another to either get the canary or Jerry. It's mayhem, with one catastrophe after another happening the hapless cat. Is imitation of a flying bat is pretty wild.
Actually, it's almost too much action. After awhile, you want to say: "stop! slow down for a second!"
Overall, however, it entertains nicely and provides a lot of laughs, which is the idea. The artwork in here is pretty good, too.
