Additionally, for this week's #AnimangaFoundIt with the main theme Cake
I just remembered the creepiest scene with cake, no cats tho . One of the darkest scenes of the third Madoka Movie, Rebellion.
Full song here, for those who want to watch it.

If anyone needs inspiration, there's lots of anime birthday cakes, like Yun Yun's solo birthday in Konosuba, or that one mouthful Yuru Yuri meme...
Natsume's book of friends has lots of Nyanko-sensei eating cake scenes too.
Muta from the Cat Returns eats cake in one scene.
