To cut long story short - shes got eye infection. Has been in pet hospital but didn't go well - think fellow patients (dogs/ cats) were too scary and she started behaving weirdly e.g. sleeping in middle of cage, walking around with little hamster tail down.
She's home now and getting some kip in her favourite corner. But I've got to do eye drops. (Now 3 hours overdue)
If you read the bitey hamster thread you'll know we don't like disturbing her bed as its her safe place away from humans.What's better - leave her a bit longer to sleep safely or get her out of bed and get her up for horrid but necessary eye cleaning and drops.
sometimes it can take them a week or so to recover from stress, watch for signs of wet tail. I wouldn't wake her, I would leave her as waking them up can be stressful in itself if it's happening regularly. if you do decide to wake her up, a little bit of warm scrambled/boiled egg wafted in her direction could do it gently. hope she improves.
