Ratcatcher

Ratcatchers are roughly cat-sized, stealthy, spider-like creatures fond of the nooks and crannies of densely populated areas. They thrive with ready access to small vermin and food scraps.

They can make their bodies extremely flat, and slip into surprisingly narrow spaces easily. They are covered all over with a fine grey fur that is surprisingly soft, and ratcatcher fur is used as a material in some styles of clothing.

Despite being widely regarded as horrifying, and certainly capable of injuring an adult human, ratcatchers are not usually aggressive towards humans unless provoked, and attacks are very rare. A ratcatcher living in the gaps between apartment buildings on your block is actually a very practical strategy for managing vermin, if you can convince your neighbours to tolerate it.
