does anyone know what causes a a discharge from the nose and eyes that becomes black and crusty? The vet doen't have a cure, and the pet shop guy sells stuff to clean it, but not to stop it in the first place. On antibiotics for a different reason it improved, and a flea collar made it a lot worse. She's had this since she was a kitten, she had cat flu when I got her and the vet suggested this damaged her eye ducts which causes the discharge. Anyone got any ideas?
