This black dirt could simply be from Simba getting dirty, or it could be flea dirt (flea poop). I would make sure that he is up to date on his flea medications, giving him one if he isn't. I can give you a flea treatment program for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. I hope this helps!
