I just noticed that Oakley's 'thumb' was red & it looks like the nail is completely missing. The injury does look a few days old though. Im assuming he got it while trying to escape from his cage I just want to make sure that there isn't anything I need to do. It doesn't look infected, but he doesn't really let me get near it...he walks/runs fine, but he does lick at it a bit. I managed to get some hydrogen peroxide on it, but other than that, should I just let it heal on its own? How can I tell if its infected?
