This is very an opinion question.
If you ask mine: I think they don't help us in daily life.
But they certainly do indirectly!
For example many products you buy are tested on animals, inclusive rats.
So without them, the scientist have to find out other manners to test their stuff on.
Rats also help people in the cycle of animals.
Rats are scavengers and eat the trash off of the streets, cleaning our roads.
They make great pets. Unlike gerbils and Hamsters, they crave human attention, and can be trained to do tricks, almost as easily as a dog can be trained.
Rats have poor eyesight, if they were people they would probably be classified as blind. Red eyed rats have even worse eyesight, and sometimes sway their head to help them focus.
I think "rats" is likely to mean "coward" who run away when they have a problem. If some one, or some people run when difficulties arise, or when things get bad, they are compared to rats deserting a sinking ship. The rats only care for their own safety, and will not stay to help prevent the ship from sinking or to help others
they mostly eat rats or mice some people feed there snakes frozens rats or mice you can get there food at local pet shops.
Food helps the rats survive.
beacause the rats stole the food
Because rats are smart and play with you
Mrs. Frisby went to the rats for help. The farmer wanted the rats removed because they destroy crops.
Not kill them.
Most certainly. Rats have been known to eat almost anything, from "people" cheese to cardboard. There have been instances of rats eating their own feces to survive. Rats can eat cheese that people eat, but people shouldn't eat cheese that rats eat unless it's safe.
rats eat the leftovers from every thing rats WILL eat ANYTHING that gets in their way! SOOOOO if i was you i would stay away from RATS because they WILL and I'm telling you WILL difinitely eat your insides!!
People captured and killed all rats. They also burnt them after.
Yes rats will bite people whether wild or domesticated. Anything with teeth can and will bite
