Taking care of pet rats
Pet rats are kept in groups in wire cages. Each pet rat should have a space of at least 2 cubic feet. The spacing between wires depends on the size of the rats kept, it should be less if baby rats are kept in the pet cage. Paper based cat litters may be used in the cage, which should be cleaned at least once a week.
Rats are omnivorous animals, and need both plant and animal sources of food. Most mixed grain diets available at pet stores do not provide adequate nutrition. Lab blocks are recommended and fruits may be given to the rats as treats.
