Just occurred to me as we have acquired two gerbils, planning on taking them with us when away over NY in lake District. They will stay in their (large, humane, filled with toys cage) and I will hoover up any bedding that they spill over.
Do I need to let the rental owners know ? It's not like a dog where there would be fur shedding and smell so I don't feel we should have to pay extra for it.
