Ham proofing

[Bellatrix]

Hey all,

I'm not sure if this is the right place to post this but here we go.

I want to ham proof my bedroom for Witchtel to be able to have free roaming time. I took her in the bathroom last night and let her run around and she LOVED it but my mum freaked out on me (not because she doesn't like rodents but because she's obsessed with our cat and reckons the cat gets upset when I take Witchtel into any other room *major eye roll*).

So, I'd like o hamster proof my room, I've tried various play pens, bins, big boxs but she hates them! Literally hates them. But she loved running about on the floor last night.

Do you have any tips? Obviously block up any holes, but how do I stop her going under the bed? I don't really want her going under there, I've got lots of storage boxes and the likes under the bed, I'd never find her again.
