Cat Tear Duct

: Tears normally drain through small holes in the eyelids into the nose. If these are blocked by debris or inflammation, tears overflow onto the face, often causing a reddish-brown stain due to iron-containing porphyrins.

A blocked duct becomes a breeding ground for bacteria. Signs include a thick, yellow-green or bloody discharge from the corner of the eye, swelling just below the inner eyelid, and sometimes pain. cat tear duct
