[Bye Bye Papaya]

Thank you, souffle! This is great practical advice. I've never had a pet before, let alone a hamster, so your tips and support are really appreciated.

I haven't found any damp areas in the cage yet. She only pees a tiny amount so I expect any urine has dried out.

I have one of those bendy wooden bridges so I'll swap it with the plastic house next time I refresh the substrate and do some tidying. Hopefully the change won't scare her too much.
