You can unlock Big Head mode by making some music with the bell and the phone in the lobby, where your clients are waiting. I clicked randomly on these two items and unlocked it. I've read people saying that they've played a minute or others doing known songs, like Jigglebells. Big heads will disappear upon restarting the game.

The cat appears in the background, after a date, when the two persons are outside and deciding if they'll see each other again or no. However, the animal appears randomly. Just click on it 25 times (one per date).
