Watch out for Rat Attacks!
Rats are feral pests that can bite. Rat bites are a threat to which anyone is exposed at home! But usually they don’t bite with no reason, however if the rat is cornered and feels endangered, it’s very likely that it will approach and even attack a human. As will many wild animals, if provoked rats will fight their way out of the confrontation.
And no, a rat won’t bite you in your sleep.
