Anecdotes

The end scenes were a likely nod to the WB duo of Coyote and Roadrunner, as Roadrunner always got away in the end, sometimes with the help of planes, trains, or automobiles.

Once again, beautiful attention to background detail here, one of the hallmarks of animation's golden age. The exposed brick under the building's plaster, Jerry's detailed mouse hole door with its small light, the Canary's furnished birdhouse, even the shadows cast by the open windows on the structure behind, all are drawn with careful precision.

The cute yellow Canary like bird seems to be a combo of Tweety and Lil' Quacker.

Tom's wings are actually an old fashioned corset undergarment, used in an unconventional new way. It slipped past the censors of the day, probably because of the humor involved. Showing undergarments in general were just this side of the censorship rules, even for cartoons.

For a brief second, when the canary is literally scared out of its feathers, he's seen wearing an old fashioned red Union suit long undergarment. Blink and you'll miss it.
