Oh right - sorry I didn't get what you meant. Re-reading your post I see you explained that so my bad.
Well if it was me I wouldn't feed her untill I knew if I was going to have to disturb her for a vet trip or not. Might be an idea to try and get someone to help you get a better picture so the folks who know more than me can say what they think it is.
It could just be an irritated area where the old skin detatched - or even a blood vessel, without the pics It's just speculation really![]()
Play about with the camera for a bit with something else in your hand to see if there is anything you can improve - the one I have doesn't do close up very well but if I hold it further away I can zoom in and get a slightly better pic.
