How long are you going away for? I would just write down the basic hamster care such as changing water, when she needs to be fed, making sure she is ok. But make sure her cage is filled with plenty of toys and enrichment (such as hiding treats/food in small cardboard boxes) to keep her happy. I would recommend that your friend doesn't handle her if she doesn't feel comfortable doing so as this will be the least stressful.

At night would the cat be in the same room as Peanut? as this would be the time I would most be worried if no one is there to supervise the cat around her cage.
