Q. My 6 mo old cat has nasal/ ear problem on the left side. There is dark wax that comes out easily but he sounds like he's snoring when he's awake.

A. Poor kitty sounds like he has upper airway infection that sounds as though it may be caused by what is called a nasopharyngeal polyp (a round sac of tissue that spontaneously forms in cats especially bad causes unilateral/one sided ear and nasal infection).
A vet should have at your kitty tot take a look inside the ear if they also suspect this may be the cause.
Another possibility would two separate disease processes that are just occurring at the same time, particularly a viral infection of the airway and an ear infection (caused by mites, bacteria or yeast).
