Hi I was thinking about your daughter liking pink and it fitting in with her room and had an idea...
How about buying something like a Kios cage or a zoozone one and decorating it? I don't mean with paint as that would be a high risk to the hamster but with stickers and transfers?
The Kios I've ordered has a grey base but I've 2 other hamster cages and a guinea cage in my room & they are a mix of greys and blues, I've got names on & did add some butterfly stickers to the guinea cage as I'd some spare from a pack I'd been using on a mirror. Those were 99p from the Range.
You can get cheap art & craft supplies & your daughter could on the outside stick nice transfers, a name label etc on. Market stalls can be good for wide strips of ribbon but you'd have to make sure the hamster couldn't reach anything added.
Just an idea - I don't know how old your daughter is but I work in a college with teenagers and know some of them have made name labels for their animal cages/hutches - you'd just need to be careful no Sellotape goes where hammy could get to.
Just an idea - might be easier to buy a light grey based cage and add some pink decorations on the outside - would be cheaper than me buying a duna then a few weeks on buying a Kios as I've realised my hamster needs more space
