I expect you should as she'll probably lick her paws whilst cleaning herself. Maybe try walking her over damp kitchen paper or giving her a temporary sand bath and hope it comes off in that? If you feel confident enough you could maybe try to gently rub each paw on the kitchen paper, obviously be careful not to hurt her. I pressume you know not to bath her in water. I hope that helps
Well done on finding her! I once had a hamster, Willow escape behind the freezer. Rather than grabbing the oppertunity to capture her when she remerged, I made the mistake of trying to take photos of her...ended up staying up an extra hour on a school night��
I like to think she had an exciting wee adventure though! X
