Kindergarten Wolfartsweier in Karlsruhe, Germany is the perfect school for cat lovers. 

Designed by Tomi Ungerer and d’Ayla-Suzan Yöndel, the building is shaped like a cat resting in a sphinx-like position. Round windows make up the cat's eyes, while the front door serves as its mouth; students venturing inside will feel like they're being swallowed whole. In the interior, you'll find two floors, with a kitchen, coatroom, classroom, and multiple play areas. You can exit out the back through the tail, which doubles as a slide (there are also stairs for the slightly older-at-heart).
