Move your hand slowly while your rat is aboard, so you don't frighten it. Once your rat is comfortable in your hand, consider giving it even more freedom. Rats enjoy the opportunity to run around and explore outside their cages. It's not only good exercise but also makes them better pets, allowing them to develop their intelligence and personality. Many people don't let their rats run around on the floor but instead give them access to furniture, such as beds, couches or table tops.
Most rats confine their roaming to areas they grew accustomed to while young.
So, if you prevent young rats from leaving the furniture, they will have little desire to get down on the floor when older. Because of their habits of chewing and urine-marking, you may want to protect furniture with a washable throw cover before their excursions. If your rats don't have free access to their cage while out, you should place them back in their cage once every hour to give them the opportunity to relieve themselves. The first step is to seal any holes in the walls or floors where your rats could disappear. Although fully socialized rats won't try to run away, they could get scared and refuse to come out.
