Nekokaburi 猫かぶり - (literally ‘cat cover/veil’) feigned innocence or naiveté, wolf in sheep’s clothing
Cats are good at many things, but looking innocent when they are obviously guilty takes the cake.
“What? You think I knocked the Lego masterpiece off the shelf? I wasn’t even in the room! Look into my eyes…they’re full of innocence!”
Putting on a “cat veil” may make you look innocent, but we all know you’re just the wolf in sheep’s clothing.
