Our hamsters live in the bedrooms upstairs. Upstairs is warmer than our downstairs and our cat doesn't go upstairs so they are safer. We have sets of draws we put the cages on that we got from a charity shop. I think I am so used to hearing their wheels that they don't wake me up at all in the night, plus, their wheels are pretty silent. I sit upstairs in the evenings and spend time with them so they do get to see me
