I've never seen a cat jumping on and eating a fish in an actual scene only the animated series of Mr. Bean is my reference for that. It's probably both funny and hilarious. I'm not fond of cats and my mom never wanted a dog inside our house so I did not attempt to bring one even though I want to. Now I'm planning to get a fish because I wanted someone alive other than me inside my room. I've been coveting those very tiny fishes I often see outside the pet store, too bad I don't know what they are called.
