For a couple of days now I've noticed Izzy had a bit of a pooy bottom. I didn't think anything of it as it's happened before and she normally sorts it out herself. However today I thought I'd try and 'flick' it off, it didn't work and on closer inspection it looks as though it's stuck firm to her skin around the 'hole' rather than the hair. I made one attempt to pull it off and she yelp, I've not tried again since!
Is there anything I can use to loosen it slightly before trying to get it off again? I don't want to pull it off and cause a wound (god knows how I'd keep THAT clean) and hurt her again
