We're currently don't have enough cute cats, need someone to find more and add them here:

@kirjs why don't we actually hook up the application with a database, and from there we can fill the database with FAKE data using FAKE info generators like: FAKER

The primary reason is for the upcoming course I need it as light as possible with minimum external dependencies, ideally offline.
Also for this particular course people had a very hard time with promises (though with this kind of app we can have a promise tutorial tab)

For now we just need a few cats handpicked with love, but can do something more advanced in the future.
