Seriously, someone put this in a Nicholas Sparks film for cats.
You could call the film The Catbook. You could also call it The Notebook for Cats, but that brings up some logic issues for your audience. Do you explain to cats what a notebook is? If you do, do you have to also explain to them the concept of written language? Do you offer to help the cats create a written equivalent for their meows and purrs? The whole effort seems like it would take a lot of time, and you should instead just use that time to watch this video of cat brothers/make-out partners Seamus and Angus over and over.
