My little hamster lady moved straight into her new house with snacks and nesting material. Since then, I only ever see her there and she doesn't look for any other sleeping spots anymore.
A lovely little house that our Syrian hamster really likes! The house is good quality and fits well with the cage decor. Just a note for others: the door openings are only about 5–6 cm. Our big guy, about 200g, can still squeeze through, but they’re pretty tight. For a bigger hamster or if their cheeks are really full, the openings might be too small. But for us, it works and is in use!
