Pet rats are not vermin. Pet rats are raised in a pet store, laboratory, or adoption center and they are raised to be pets or in the case of labs, experiments. if you are thinking of buying a rat remember not to buy a rat raised as food for snakes. Rats bred to be pets are much gentler and sweeter than rats raised as food.
All pet rats are the same. They are all called fancy rats except for the Albino which is slightly smaller than the regular fancy rat. If you go to the pet store and see tanks that say small, medium, and large rat you should know that the small rats are simply babies and the large rat are older.
