CITY RATS
: The brown rat's teeth are yellow.
The front two incisors being long
and sharp, stand out like buckteeth.
When the brown rat BITES, its two
front teeth spread apart. When it gnaws,
the flap of skin plugs the space behind
its incisors - so that - when the rat gnaws
on inedible material like concrete or steel,
for example, the shavings don't go down
the rat's throat and kill it. :
-
: Its incisors grow at the rate of five inches
per year. Rats always gnaw, and no one is
certain why. Sometimes it is thought that
they gnaw solely to limit the length of the
incisors, which would otherwise grow out
of its head. But THIS is not the case. The
incisors wear down naturally.
-
: In terms of hardness, the rat's teeth are
stronger than aluminum, copper, lead,
and iron. They are comparable to steel.
I have always felt I had thoughts like that:
harder than what you'd normally find in a
bullet-proof vest, to use a POOR example
about the hardness of a rat's success.
