It looks like one of my Americanas cut the pad and fold on her claw the other day. There is only a little bit of blood and the underlying flesh looks good, but the meat surrounding the cut is dark. I'm going to double-check tonight to make sure it isn't dirt, etc. She doesn't seem to be in any pain when I touch it or when she's walking around on it. Any advice on cleaning and getting it to heal? Anything I should look for and be aware of?
