Cute! 😀

It mostly works. I think line 103 should maybe be:

os.remove(os.path.join(cdata, "teat.txt"))

So, "teat.txt" instead of "eat.txt". I think this prevents the cat from ever getting happy since that line causes an error and it never reaches image.set_from_file(os.path.join(current_dir, "data/happy.png")) which is very sad!

Actually, you may just want to catch the error if the file happens to not exist. Like this:

    try:
        os.remove(os.path.join(cdata, "teat.txt"))
    except FileNotFoundError:
        pass
