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.
This was a solid and highly enjoyable 'birds vs. cats vs. dogs' cartoon I found as an extra on my DVD of the Lewis Milestone-directed war film, 'Edge of Darkness', starring Errol Flynn. Great ending! =)
