ok, ive had my two baby rats for 5-6 week, there about 12 week old now, since ive had them ive been handeling them everyday and letting them run up my jumper ect..but im scared to let them on the floor by them selfs, in my house i have no spare room and i keep them in the living room with us but i have wires near the t.v and i wouldnt want them to chew them. should i let them go out on the floor and let them wonder the room for them selves? would they chew the wires? would they come back to their cage? sorry about all the questions, bet you can tell im a first timer with rats.lol
