Hoppy Daze

Storyline
When Palooka Pussycat (A short, older cat, who sounds like Jimmy Durante) can't catch mice anymore, he decides to train Sylvester into becoming a champion mouser, for a share of the mice. And that training might not be any good when Sylvester comes across the baby kangaroo, Hippety Hopper, whom he mistakens for a giant mouse inside of a warehouse.
