How can I tell the difference between flea dirt and regular dirt? - Advanced Animal Care
Flea dirt is digested blood, and so we have a fun trick here that we'll do in the clinic where, if we're suspicious of it, we'll put that dirt on a paper towel, and we'll get it wet. And what happens to dried blood when you get it wet is, it turns back into that normal red blood color.
