Well then, tell me how you feel about rat-squirrels? Nearly two feet in length (not including the tail) bigger than a grown mans thigh, with dirty, patched fur. They can stand on their legs like squirrels and jump like them too, run faster than a rat, can gnaw through metal and cement, are fearless enough that instead of running like a normal rat or squirrel, these little demons will charge at you. Oh, did I mention that they'll probably do so while screaming at you? Yes, that's right, these vile spawn of hell can scream.
Oh, and they are also heavily resistant to poisons that usually kill rats.
Ladies and gentlemen, another fine product from my country, aided by mother nature, all in an attempt to prove to us: Hey, the human race really can f*ck itself over!
It's almost as bad as the African Honeybees . . . :D
