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 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.
Because rats are smart and play with you
beacause the rats stole the food
Mrs. Frisby went to the rats for help. The farmer wanted the rats removed because they destroy crops.
Not kill them.
Yes rats will bite people whether wild or domesticated. Anything with teeth can and will bite
People captured and killed all rats. They also burnt them after.
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!!
I don't know, maybe because of the wild rats. The wild rats are nasty, and spread diseases, but then people add that detail to the domesticated pet rats. I think pet rats are very clean, if you take care of them. Hope I helped ^^
