 An old woman has a cat, a dog, and a canary. The cat and dog fight even worse than normally; fed up, she tells them both off, then threatens to throw them both out if there s any more trouble. The two then spend the rest of the picture framing each other and summoning their master: first, the dog unleashes a whole box of mechanical mice, which the cat manages to sit on (they carry him right into the basement); the cat stamps dirty dog footprints all over the room, but because the dog plays air raid warden ("put out that light!"), their owner doesn t see them. The dog glues canary feathers to the cat, but the canary pops out of hiding; the cat uses shaving cream to make the dog look rabid. Finally, the canary, fed up, frames both of them; they attack its cage just as their owner arrives, and both are thrown out but, as it turns out, the smiling cat has taken the bird with him.
