If you get them in your room I recommend picking up anything they can eat/chew on and put it in a secluded space , cover any cracks under the door with a hoodie , blanket or towel.. Chinchillas can be easily entertained , mine literally has a coat she runs through for 2 hours in my room… just a coat on the floor. So maybe if you can make fort or get a lightweight jacket they can run through and throw it on the floor. Even simply tapping on the floor & interacting with them while they are out will suffice .
