[2] The canary in this short was a primary inspiration for the design of Maurice, a character from The Wacky World of Tex Avery.

Disgusted with the tiny creature at first but still desperate, the cat gets a (literal) brainstorm when he sees a bottle of Jumbo Gro plant growth formula on the shelf.

While the now giant-sized cat chases the slightly smaller canary through the side of the house, the bulldog guzzles down the formula.

After a quick run around the block, the cat and canary wind up back outside of the house, where a now gigantic bulldog appears before them.

The dog chases the cat through the city, only for the now gargantuan mouse to show up and scare the bulldog away with a simple "Boo!".

The cat rubs his enormous belly, realizing he is still hungry, then sees the huge mouse waddles off and gets another idea.

The cat, who is by now one hundred stories tall, chases the giant but smaller mouse through the city and across the country, passing the Grand Canyon, the Hoover Dam and the Rocky Mountains.

They wave goodbye to the audience before the camera pulls back, revealing that they have outgrown the Earth itself and are standing atop the globe.
