Since I got my gecko a couple months ago, she's had shedding on her back foot that hasn't come off. I didn't think much of it until I noticed she had lost a couple toes. Just today I tried to get the months-old shedding off by soaking her foot in hot water and nudging the shedding with a q-tip, and it looks like her entire foot is about to come off. I couldn't get the shedding off without seemingly separating her foot from her body. I'm pretty sure there is no saving the foot at this point (it breaks my heart just thinking about it!) but I don't know what to do. Do I just let it fall off naturally? What can I do to prevent the spread of infection? Please help!!
