Black Dirt In Cats Fur. While cat acne is often visible on the face, flea dirt has a different presentation. Just like in humans, these glands secrete oil that can block hair follicles, causing a comedone—or blackhead—on.
As the fleas feed on your cat, they will pass digested blood, also known as flea dirt or excrement, which will appear as minuscule black flecks on your pet’s skin and fur. Pat the coat dry with clean towels. If you still suspect there's pollen on your cat's fur, drizzle water over her coat to rinse away any last pollen particles.
