It happens! Rats can emit over 8,000lbs of pressure per square inch with their jaws. Their tooth enamel is one of the hardest substances on the planet.

Couple all of this with the fact that rats can dive under water & swim like Olympic athletes. It is no wonder rats get into our buildings & homes.
