Panicking!!

[Caran]

I have Maggy to stay, she is a hamster belonging to grandchildren who have gone on holiday.I let her run round in her ball each night for a few hours, last night I let her run round on her own, having shut all doors out of lounge.
Tonight she had her ball run around then a run around on her own, she has been missing now for 45 minutes, I have searched with a torch and cannot find her. When do I go to pet shop and buy another one?

I'm glad she's home!
