Greedy Cat’s Door

My own Greedy Cat was black and white and weighed 10kg!
One day I growled at him for stealing food. Off he shot, like a rocket, out through the cat door. But his extra lunch took the door off its frame, and he ended up in the back yard, wearing a cat door around his middle like a funny skirt.
Now, there’s an idea for a story, I thought.
