Clumps of fur and pet dander in the shape of a ball or nugget. Long hair cats have a tendency to shed more and therefore more fur tends to come off of their body.

Often stuck onto carpet or flooring, because of in-house traffic. It has to be sucked up with a vacuum hose or picked up with your own hands.

Sometimes a cat sheds so much fur, furnugs create carpet on top of the carpet or floor that is already there.
Kyle: Ewww. Look at all those furnugs on the carpet we could open up a carpet business!!

Patty: I know, my cat sheds a lot. The only problem with that is some people are allergic to cats.
