Ratmans!! ᘛ⁐̤ᕐᐷ
I have a theory that spies are genetically mutated rats created for espionage. This can be partially confirmed by canon: they are small in stature, they have limited sounds (mostly giggles, sighs and similar, inarticulate sounds), in one of the episodes a mouse was introduced that looked like spies with its face and eyes.
SI'm sorry if the text was difficult to read, I used a translator.
