As a joey, their nails are pretty sharp but really shouldn't need trimmed yet.
As far as scratches, since she is still growing accustomed to you and I see from another post, you're having to catch her. ( I'll get to that in your other post).
If the scratches are a bit red or inflamed, treat them with tea tree oil once you have washed the area. It works on healing the fastest that I have found.
Back to trimming. Are her nails getting caught on her bedding, or just skin scratches?
like she is pretty stressed, but a vet
well check is a good idea (if you click on vet
it will take you to a database where you can find a vet
near you that sees gliders)
