NARRATOR:
It’s an urban dweller’s worst nightmare …
A rat in the toilet… It’s scary, but it does happen.
Washington D.C.’s Rodent Control receives a couple of
complaints each year…
DC RODENT CONTROL OPERATOR:
Good afternoon, you’ve reached Rodent Control. ... You have a rat in your toilet?
NARRATOR:
How does this ultimate rat invasion actually occur?
First, it could easily sneak into grates or manhole covers
open to the street.
Residential sewer pipes feed into the main tunnel.
A rat might consider this path an irresistible opportunity
for exploration.
Its sharp claws allow the rat to scale almost any vertical
surface.
The rat is in the home’s internal pipes, going up.
Now it faces the biggest test: getting through the last few
feet of the narrow, maze-like toilet pipes.
Is this even possible?
The underwater passage leaves no room for error.
At a turn, the rat finds a pocket of air, just enough to
help it push on...to the end of the line.
How does it collapse its body like that?
Take a look at this rat’s attempt to get to the other side
of the tiny hole.
If a rat can fit its head through an opening, the rest is
easy because of its “internal acrobatics”.
When squeezing through a constricted space, the pressure
causes the ribs to give way.
At the spine, the ribs are hinged allowing them to
effortlessly collapse.
How does the rat deal with all that...water? What if someone flushes?
We think of rats as land animals, but it turns out, they’re
expert swimmers.
Rats paddle with their back legs while the front feet steer.
The tail also works as a kind of rudder.
Rats have incredible stamina—they can tread water for three
days straight!
And they can hold their breath underwater for up to three
minutes.
This aquatic proficiency is the very reason rats became
global travelers.
Long distance swimming enabled them to hitch rides on boats
and colonize new shores.
