Looney Tunes S1933E23 - Sittin' On A Backyard Fence

It's the middle of the night, and everyone's asleep except for the house cat (a girl) and alley cats (boys) on the fence competing for her attentions. A bull and three cows from ad posters on the fence sing "Sittin' On A Backyard Fence" and a cat band, using junk instruments play. Two boy cats, one drunk on catnip, fight each other over the girl, and get chased and knocked out by a dog. The girl cat leaves with another male cat, followed by kittens that are obviously theirs. The two fighting cats then shake hands.
