In long-haired breeds of cats, it is common to get an accumulation of brownish matter at the inner corner of the eyes and permanent runs of tears down the face. This matter should be bathed away with lukewarm water or boric acid solution (two 5 ml teaspoonfuls of crystals in half a tumbler of warm water), and your vet consulted if it persists.
