A worldwide community photographing and learning about wildlife

If they're in a place where I can be reasonably certain no one will find them, I like to let them grow a few more days (possibly up to a week depending on weather), and pick them just as they begin to redden.
I can't tell by the photo, but if the mid-dorsal scales are keeled then my identification as a black rat is positive. Otherwise, I'm going by the description and comments as to its behavior.
