Fantasy world with sizeplay inhabited by furries and fae alike. The catch? Sizes are reversed.

Mice and fairies dwell in roomy abodes, living lives and working jobs, while larger species' are borrowers, surviving in the cracks and crevices in homes far larger than themselves. Essentially: smaller species' are the large ones, while the larger species' are the small ones.

Thus, a cute mouse might either complain about the 'pest' of a feline found under floorboards... or find the rather tiny, bug-sized cat to be kinda cute.
