I don't know where to even start explaining this. I have noticed over the
last few weeks that my cat has what looks like black grit on his chin. At
first I thought it was flea dirt (even though I use frontline) but I combed
him and there was no fleas, he has been re-treated and but he still gets
this black gritty stuff in the fur of his chin. Anybody got any ideas what
it could be? It's not bothering him, just me!!

TIA
