"My hamster like to climb through it, and LOVES sitting on top of it like a perch, so she can see what is happening in my room. However, she doesn't like to eat it. I don't know why, maybe it just doesn't smell great to her. I was fine with keeping it in her cage until she started peeing in it. It rotted and now had splotches of white-brown yuck, and I am going to throw it out."
