Rats can cause a lot of damage to your home since they can chew through almost anything, including wood, cardboard, plastics, aluminium, and electrical wiring. But why do they do that? You see, they have four front teeth called incisors that can grow several inches in a year, which would cause severe pain for the animal. So they chew on materials in their environment to grind the incisors to keep them filed and pain-free.
